Don’t forget the history:the biochemical persecution experienced by the Chinese people on the anti-fascist battlefield (be cautious)

Note:This article may cause your unpleasant feelings, please think twice before continuing to read!
Analysis and testing science has brought unprecedented improvements to our quality of life. More and more precision instruments play a vital role in safeguarding our health, food safety, industrial product quality and other aspects of clothing, food, housing, and even aerospace.
but
Yes, science is a double-edged sword. The negative use of scientific achievements will cause great harm to mankind! On the occasion of the 70th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War, the Analytical and Testing Encyclopedia has collected historical data on China’s biological and chemical experiments and persecution in the biochemical warfare during the World Anti-Fascist War, using bloody reality to appeal Do not forget the history of your colleagues in the analysis and testing industry and warn future generations.
Because a large number of historical photos are too bloody and cruel, AnalysisTest Encyclopedia tries not to show readers those excessively outrageous photos.
Unit 731
Unit 731 cannot fail to mention the”engine” that launched chemical and biological warfare for the Japanese invasion of China. Its full name is the 731th Anti-epidemic Water Supply Unit of the Japanese Kwantung Army in Manchuria, and it is the code name of the bacterial warfare preparation factory of the Japanese invading army. This
The Devil Army established the largest and most extinct germ warfare research center in human history in China, and used ordinary people to do living experiments to destroy the lives of Chinese people. This unit has a total of 4 specializing in bacterial research
With the experimental institutions and 4 teams, the total number reached more than 3000 people. At the beginning of its establishment, Unit 731 was a veritable germ special warfare evil force. It completely obeyed and served the war. From 1932
Started several years of appalling anti-human activities such as germ warfare and in vivo experiments on humans.

Vivisection:One
A special human test project code-named”Ma Lu Da”:The subjects were all captured from Chinese residents, also known as”Ruan Mu” (Maruta). The main point of this task is:it is necessary to ensure that the anatomical object is absolutely awake, that is, absolutely not anesthetized. Because Japanese military doctors believe that the post-anaesthesia research data is untrue. The anatomy scene is tragic. During the autopsy, the screams were unimaginable by ordinary people. This job is also a basic skill necessary for all doctors of Unit 731.

Grenade test:People will be tested at different distances and positions.
Frostbite test:used to test the degree of cold resistance of a person at different temperatures. The test data is the data of a field frostbite test conducted jointly by professionals from the North China Epidemic Prevention and Water Supply Department and the Mongolian Army Corps. The title is”Extremely Secret · Winter Hygiene Research Achievements of the Mongolian Army”. The data was compiled by the Winter Hygiene Research Class. The date is March of Showa Sixteenth (March 1941).
  
Simulation scene
This information is Jin Chengmin, the director of the Institute of Bacteria and Gas Warfare of the Japanese Invaders in China. At the invitation of Yokohama City University President Kato Yuzo, he was appointed by the Hirabo District Government to give lectures and visits to Japan. He went to Tokyo Kanda many times alone or with Japanese friends. Libraries and archives in other places looked up the materials, and found this well-preserved material in a reference room.
Flamethrower experiment:Unit 731 locked the tester in an abandoned armored vehicle and grilled it with a flamethrower to test the power of the flamethrower. But this experiment is meaningless. No armored car will stay where you are and let you bake it, which is pure”entertainment”.
Plague experiment:will
Yersinia pestis was injected into the tester’s body, and the reaction was observed. This method was also applied to Soviet prisoners of war caught by the Japanese army at the border. Development of defoliants and bacterial bombs:The most prominent”achievement” is the Ishii bomb. The pineapple bomb later used by the US military in Vietnam is also an improved version of this bomb. The Ishii bomb is a ceramic shell with bacteria-carrying bladder inside. Another invention by Shiro Ishii is the Ishii water filter. It is the only useful invention of Unit 731 to solve the problem of drinking water from sewage treatment for soldiers in the field.
Tooth extraction without anesthesia:The purpose is to test whether the wounded can tolerate tooth extraction without anesthesia. The result of the experiment is that no one can tolerate it, but it is another matter if the tooth has been severely loosened.
Human and horse blood exchange:The blood of a strong person is taken away. At this time, the whole body is convulsed, and several military doctors cannot fully hold it down. The blood of the horses was immediately transfused and the performance of the people was observed. As a result, physical rejection was obvious and all people died.
The effect of germs on the fetus:Let a woman be infected with germs after pregnancy, and perform biopsy after the fetus is formed to observe the state of the fetus.
Human-Animal Hybridization:Forcing women to mate with horses or wolves (a kind of dog), and studying the optimization methods of so-called inferior nations.
Interchange of human limbs:The limbs of the two people were exchanged after amputation. If the test is successful, it will be of great significance to restore the combat effectiveness of the disabled Japanese soldiers, but the test failed because the attached limbs showed no signs of recovery.
Vacuum experiment:for
In order to conduct vacuum environment experiments on living people, the 731st unit has an air pressure laboratory that measures the resistance limit of the human body at high altitudes to determine the tolerance of various organs in the human body under high pressure. These experiments and Hitt
The experiment done by the bandit Rahir is exactly the same. The Nuremberg International Tribunal once called this experiment the cruelest and most inhumane experiment carried out by Hitler bandits. Because a living person is in a sealed air pressure chamber, his eyeballs will bulge out after a short time, and the person will be suffocated to death. The pain is unimaginable.
Other human tests:human
All kinds of brutal and inhumane experiments that can be thought of, especially those projects that can be used to mass kill the enemy and heal their own people, the officers and soldiers of Unit 731 have done their best. Because they know that these trials are peaceful
The period is unimaginable, but for the emperor’s so-called holy war, they did not feel any guilt, and the only thing that made them feel unbearable were the animals (such as white rats). After the war, they set up a monument for those animals. The tens of thousands of people who died tragically did not even leave their ashes, and their treatment was not as good as animals.

Jilin Germ Warfare (historical photos)
The biochemical weapon developed by 731-Mustard gas The biochemical weapon used by Unit 731 is mustard gas. It is a chemical warfare agent with great toxic effects. It is used to make gas bombs. Mustard gas is a liquid erosive agent that invades the human body and can cause systemic poisoning. . Mustard gas contacts the human skin, eyes, respiratory tract, and digestive tract to cause different degrees of damage. Larger doses of mustard gas can cause systemic absorption and poisoning after being absorbed through the skin, respiratory tract, and digestive tract. Therefore, the clinical manifestations of mustard gas poisoning are diverse. The International Agency for Research on Cancer (IARC) has confirmed it as a carcinogen.

mustard
Ziqi is called an erosive chemical agent because it is an alkylating agent. After absorption, part of the mustard gas is transformed into non-toxic or low-toxic substances through metabolism in the body, and part of it is mixed with various components in the body such as DNA, protein, enzymes, etc. Reverse
Should cause cell death, tissue inflammation and other problems. The intravenous lethal dose for rats is 0.7 mg/kg, inhalation for 2 minutes, the median lethal dose is 420 mg/m3, and the inhalation for 10 minutes, the median lethal dose is 100 mg/m3. Rabbits are injected intravenously with 20 mg/kg, which causes acute toxicity. After the human body is poisoned, the lymphatic organs atrophy, the bone marrow hematopoietic tissue is destroyed, and the hematopoietic cells decrease or disappear. In severe cases, the central nervous system will experience”toxic encephalopathy”.
Biochemical weapons developed by 731-germ warfare
In order to manufacture various bacterial weapons, Unit 731 carried out experiments and researches on at least 50 bacteria such as plague, cholera, typhoid, anthrax, and tuberculosis. In order to obtain research data as soon as possible and to observe the effect of”experiment” more directly, he
They trampled on all human standards and forced the use of large numbers of Chinese, Soviets, and Koreans to conduct live experiments. They exhausted various methods, including using live humans to conduct brutal and inhuman bacterial experiments, and all the subjects were injured.
Die, dismember the corpse, incinerate the traces. They dismembered various organs of the human body, made specimens, soaked them in specimen bottles for teaching and research.
according to
According to incomplete statistics, Unit 731 produced more than 1,700 bacterial bombs between 1937 and 1942, including bombs used to contaminate soil, bombs used to spread bacterial clouds, and fragmented ammunition that caused casualties through wound infection. A former Japanese war criminal of Unit 731 confessed that his job in Unit 731 was to create bacterial weapons by cultivating fleas and mice with pathogenic bacteria. At the time
The rule is”no look, no talk, no tell others.” If someone wants to leave Unit 731 without authorization, he will be sentenced to death by a Japanese military court.
day
Kou abused poison gas on the battlefield. From August to December 1940, in the Hundred Regiment Battles of the Eighth Route Army, Japanese invaders used as many as 11 times and poisoned more than 10,000 soldiers. In August of the same year, in Zhugou, Yi County, Shandong
During the battle, the Japanese army used gas bombs filled with suffocating and irritating gases, which killed more than 350 soldiers and many villagers. In mid-October 1941, during the battle in Yichang, Hubei, the Japanese army used poisonous bombs and poisonous bombs, causing 1,600 people to be poisoned and 600 of them dead.
original
Agae, the mortar captain of the 10th Independent Mixed Brigade of the Japanese Army, ordered his subordinates to use poison bombs. He wrote in the article”Abusing Poisonous Gas Bombs”:In May 1940, during the battle in Hongshan, Tai’an County, Shandong Province,
In order to achieve the result of the aggression against China, under my command, we continuously fired gas bombs at the anti-Japanese army positions. Twenty minutes later, I went to check and saw 300 anti-Japanese soldiers fell on the ground, some of their faces turned completely purple, and dirt came out of their mouths.
And black blood, some are not dead yet, foaming. Most of the 300 anti-Japanese soldiers died of poisoning.
The former Captain of the 375th Regiment of the 137th Division of the Japanese Army Kenjiro Funagi confessed that in September 1941, he had ordered his subordinates to use poison gas in Dujiazhuang, Wanyi County, Hebei Province, injuring more than 400 students and residents.
Plague:Plague is a powerful infectious disease mainly spread by Yersinia pestis through rodent fleas. It is a natural epidemic disease that is widespread among wild rodents. Clinical manifestations are fever, symptoms of severe toxemia, lymphadenopathy, pneumonia, bleeding tendency, etc.
In order to maximize the lethality of bacteria, Unit 731 continuously studied the best way of spreading bacteria, and finally found that fleas were the best vector. When fleas are infected with bacteria, each fleas becomes a mobile”small bacterial infection source”. Infected fleas are very likely to cause large-scale spread of bacteria whether they attack people or livestock.
for
A large number of bacteria-infected fleas were produced, and Unit 731 specially set up an insect class. The production process of contaminated fleas is more complicated. First, a large number of fleas are raised with the blood of ordinary mice, and then the ground squirrels infected with Yersinia
In the flea container, because ground squirrel is a kind of bacteria-preserving animal, it will not die from being infected with Yersinia pestis in a short time. After a period of time, fleas that ingested a lot of the blood of yellow squirrels containing Yersinia pestis became a source of small bacterial infections. Finally, these bacteria-infected fleas can be scattered in the war zone, and the bacteria war can be carried out on a large scale.

Cholera:Huo
The disorder is caused by Vibrio cholerae. The two serotypes of Vibrio cholerae O1 and O139 can cause outbreaks. Most disease outbreaks are caused by Vibrio cholerae O1, which was confirmed in Bangladesh for the first time in 1992.
The O139 type is limited to Southeast Asia. Non-O1 non-O139 Vibrio cholerae can cause mild diarrhea, but will not cause epidemics. Recently, new mutant strains have been discovered in some parts of Asia and Africa. It is observed that these strains can cause more serious cholera disease and higher mortality. Vibrio cholerae is found in water, and the most common cause of infection is the consumption of water contaminated by the patient’s feces. Vibrio cholerae can produce cholera toxins, causing secretory diarrhea. Even if you no longer eat, it will continue to have diarrhea. Rice-washed stool is a characteristic of cholera.
Anthrax:Charcoal
Gangrene is caused by Bacillus anthracis, a zoonotic acute infectious disease. Humans are infected by contact with sick animals and their products and eating meat from sick animals. The main clinical manifestations are skin necrosis, ulcers, eschar and surrounding tissues, extensive edema and toxemia symptoms, subcutaneous and subserosal connective tissue hemorrhagic infiltration; poor blood coagulation, coal tar-like, and occasionally cause lung, intestine and Acute infection of the meninges, which may be accompanied by sepsis.
731 Linkou Branch Minister Hideo Sakakihara confessed his crime:”In preparation for the germ warfare, I ordered the first section chief Hosiya Sosa to carry out the preservation and cultivation of bacteria.” Based on the production volume at that time,”as if scattered on the eastern ground of the Sino-Soviet border. Not only can it destroy a large number of Soviet troops, but it can also reach an amount sufficient to destroy the peaceful people of China and the Soviet Union.”
In early March 1945,”Bring 2 test tubes of typhoid bacteria and type A paratyphoid bacteria kept and cultivated in the branch to the first virulence inspection team of Unit 731″,”put one or two in the well A test tube can achieve the purpose of massacre.””As a result of experimenting with this kind of effectiveness, I killed four Chinese patriotic people.”
In April 1945,”I participated in the murder experiment in Anda, Heilongjiang Province.””Four Chinese patriots” were”tied to the pillars of the Anda exercise field.””A light bomber dropped a pottery bomb at 50%. Air burst
Fried.”I put on a full set of preventive clothing and watched this brutal atrocities from a distance of five to six hundred meters. This bomb is filled with the terrible anthrax bacteria. Let them inhale lung charcoal from the nasopharynx cavity, which has absolutely no hope of survival
Gangrene, or skin anthrax caused by fragments, I also participated in this crime.”
In order to prepare for the germ warfare, Unit 731 frantically studied the manufacture of dozens of infectious bacteria such as plague, typhoid fever, cholera, anthrax, typhoid fever, etc. The production capacity is so large that the number is shocking. Unit 731 can produce 3,000 kilograms of pure bacteria each year. And every 135 grams of pure bacteria can pollute all water sources within 400 square kilometers, so how terrible the damage of an annual output of 3,000 kg of pure bacteria is. In the first half of 1945, in order to prepare to spread the plague, the Japanese troops stationed in our Heilongjiang Province alone handed in 56,000 rats to Unit 731.
The Japanese bacterial force once organized expeditions to carry out bacterial warfare across China. In 1941, Japanese Army Unit 731 and Nanjing”Rong” Unit 1644 cooperated closely to plant plague bacteria in Changde, Hunan.
Living experiment is another big atrocities committed by the Japanese army. In preparation for the germ warfare, the Japanese army brutally used Chinese prisoners of war and civilians to conduct live experiments. More than 3,000 people died in the live experiments of Unit 731 alone.
In addition to Unit 731, the Japanese army has a little-known unit in Qiqihar, Heilongjiang Province, namely Unit 516 of the Kwantung Army Army Chemical Research Institute. It was this force that conducted a large number of chemical weapons research, experiments, development and production, which caused the Japanese army to use chemical weapons on a large scale and frequently on the battlefield, causing great harm to the Chinese military and civilians.

These bacterial warfare units and research institutions of bacterial warfare research and manufacture bacterial weapons, use them to attack Chinese troops and slaughter the Chinese people.
The appalling biochemical warfare The Chinese people suffered tremendous trauma from biochemical warfare in the anti-fascist war. Only part of the historical facts are as follows.

Tens of thousands died in Zhejiang
In June and July of 1939, Xiaoshan and Shaoxing were attacked by bacterial weapons. Until the victory of the Anti-Japanese War, bacterial epidemics continued to wreak havoc in vast areas of Zhejiang. The Japanese Army Unit 731 and Rongzi Unit 1644 carried out bacterial warfare in Zhejiang.
The main force of machine attacks. There are 8 cities and about 30 counties in the province that have been attacked by bacterial weapons. According to incomplete statistics, bacterial weapons such as plague, anthrax, cholera, typhoid (paratyphoid), diphtheria, and dysentery have caused approximately 60,000 deaths and injured hundreds of thousands in Zhejiang.
In July 1940, the Japanese Army Manchuria Unit 731 and”Rong” Unit 1644 sent planes to Ningbo to spray toadstools. A total of 70 kilograms of typhoid bacteria liquid, 50 kilograms of cholera bacteria liquid and 5 kilograms of fleas contaminated with plague were dropped. Zhejiang
It is a key area for the Japanese army to conduct bacterial warfare. The Japanese Army Unit 731 lasted 5 months and dropped a large amount of bacteria-carrying poison in Zhejiang area, making the plague epidemic in Zhejiang area. In the spring of 1941, the Japanese Army Manchuria Unit 731 dropped a poison containing plague bacteria in Changde, Hunan, causing the plague to spread in Changde, killing thousands of people.

Yinhua, from Donggeng Village, Xinxin Street, Kecheng District, Quzhou City.”When I was young, my family was too poor to see a doctor, and I scratched it with my hands when I couldn’t bear it, and the scratches were bleeding and pus. Now the conditions are good, and people often come to us for free treatment, but the left foot is always incomplete, and I still walk with crutches.”(Photographed on September 8) In Quzhou, Zhejiang, there are still more than 200 elderly people suffering from”rotten feet”. They are all victims and real victims of the bacterial warfare during the Japanese invasion of China more than half a century ago. witness. They will never forget that on October 4, 1940, at 9 o’clock in the morning of that day, the Japanese”731″ troops first airdropped a large number of grains of wheat, millet, cotton, and fleas with plague and other pathogens in Quzhou, Zhejiang Province, which has a military airport. The germ warfare of evil began quietly. Subsequently, many patients with”rotten feet” appeared in the area along the Zhejiang-Jiangxi Railway where Quzhou is located. According to the victim’s recall, “At the beginning, the legs were itchy, and when they were scratched, they were rotten and pus. It has been up and down until now.” Michael Franzbrau, professor of dermatology at the University of California, San Francisco, 2005 During the local field investigation, it was judged that these”rotten feet patients” were most likely victims of the spread of anthrax and melioidosis in Japan. In its final ruling made by the Supreme Court of Japan in 2007, it recognized the fact that the Japanese had carried out germ warfare in Zhejiang, Hunan and other places, but rejected China.
Claims of the plaintiff. In the bacterial warfare of the Japanese army, Quzhou was seriously affected! Statistics show that 37 people were diagnosed with plague in Quzhou that year, 35 people died, and the death rate was 95%. From 1940 to 1948, there were more than 300,000 plague cases and more than 40,000 deaths in Quzhou. In addition, there are a large number of patients with”rotten feet” who survived the war, but suffered from illness throughout their lives.

Historical facts of Luxi germ warfare
In the summer of 1943, there was a severe drought in Luxi. In August of that year, the Luxi area ushered in heavy rain. Ten days of heavy rain caused the water levels of the Weihe, Zhanghe, Fuyang and Hutuo rivers in the Luxi area to soar. At this time, the Japanese troops stationed in Linqing dug embankments to release water, and the flood flooded the village and farmland. What is puzzling is that the plague (cholera) is rampant wherever the flood reaches. In many villages, hundreds of people died overnight, with corpses all over the field. The tragic scene of”death early by someone buried and no one carried late” was staged in Luxi. From late August to late October, more than 200,000 peaceful Chinese residents died in 18 counties in northwestern Shandong alone.
The culprit who single-handedly launched the Luxi germ war was the notorious Okamura Neji and Ishii Shiro, and the direct commander was Hosokawa Tadayasu. Japanese military planes spread the cholera bacteria to the Weihe River Basin, and then dig dikes to spread. The Luxi germ warfare was the core secret of the Japanese high-level military, and there were not many insiders. When the Japanese surrendered, they tried their best to exterminate the spoils. Therefore, this shady scene has been concealed for more than half a century.
According to secret statistics from the Japanese military, the cholera plague spread to 24 counties in the Luxi region, and more than 427,000 Chinese civilians died. In addition to indirect victims in other regions, countless compatriots died.
In addition, according to the”Selected Materials on the Party History of the Hebei, Shandong and Yu Border Regions of the Communist Party of China”:”There has been a large-scale famine in the northwest of Shandong…”No Man’s Land” where 400,000 people died in more than 1,000 villages in 4 counties, Xin County, Guan County, Liaocheng, and Tangyi.”
day
Lin Maomei, a Japanese prisoner of war, confessed that the”Showa Eighteenth Autumn Luxi Operation” was personally directed by the commander of the North China Front Army, Neiji Okamura, and Shiro Ishii, the highest authority on the Japanese germ warfare. It was the 59th Division of the Twelfth Army that carried out operations, and the division commander Tadayasu Hosokawa made specific arrangements. Lin Maomei also confessed:”The epidemic prevention and water supply team of the 59th Division, from August to September 1943, spread cholera bacteria in Guantao, Nanguantao, Linqing and other places in Shandong Province.
In Weihe, the river embankment was dug up again to allow water to flow into various places so that it can spread quickly… The bacteria was handed over to the 44th Battalion Military Medical Lieutenant Kaki Tim Shinobu and sent to spread.”
The Japanese prisoner of war Kikuchi Yoshikuni also confessed:”I participated in this operation as the machine gun unit captain of the First Brigade and helped the Japanese imperialist army implement the most brutal germ warfare. I now confess this crime and plead guilty.”
On April 15, 1938, when the Japanese army was besieging the Jinchaji Anti-Japanese Base Area, they caused the shocking Xiying Massacre in Wuxiang in Shanxi. They massacred 226 civilians. When more than 70 people escaped into a cave,”the Japanese pirates did not dare to go in after they found out, they injected poisonous gas and killed them inside.”
On September 30, 1941, a total of 6 divisions of the 2 armies of the Chinese Army and the 13th Division of the Japanese Army fought in Yichang, Hubei. The Japanese army used chemical weapons on a large scale four times, causing a large number of casualties to the Chinese army and residents.
On May 27, 1942, 2000 soldiers from the 163 Wing of the 101st Division of the Japanese Army surrounded Hebei Beituan Village, blocked the tunnel leading to the outside of the village, and injected poison into the tunnel, resulting in the death of more than 800 soldiers and civilians in the tunnel. Historically called the”Bei Tuan Massacre”.
day
This war of aggression against China was the most frequent, extensive, and longest-lasting chemical war in the history of human warfare after the First World War. Among them, there are as many as 1241 cases with the exact time, location and injury records, and the use locations are all over 18 provinces in China. Harbin released a batch of official documents and order documents of the Japanese germ warfare units. These archives were formed from 1929 to 1943, and mainly included the command documents of the Japanese Cabinet, the Army Ministry, and the Kwantung Army before and after the establishment of the”July 31″ troops, as well as official documents such as military resumes and combat orders. Some of the documents involved Nomonhan germ warfare, Zhejiang germ warfare, and other related germ warfare and human experiments, as well as the personal information of the main members of the”731″ force, such as Ishii Shiro and Kitano Masaji. From these files, it can be concluded that the Army Medical School, the 731 Army, the 100 Army, and the epidemic prevention and water supply departments are all part of the Japanese germ warfare and human experiment system. It is understood that since 1939, the Japanese bacteria troops have carried out bacterial attacks in Nomonhan, Inner Mongolia, Quzhou, Ningbo, Zhejiang, Changde, Hunan, and western Yunnan, resulting in a pandemic. The number of deaths due to bacterial warfare exceeded 2 million.
Japanese scholars Kentaro Awiya, Yoshiaki Yoshimi, and Matsunojo have compiled a collection of top-secret data on the invasion of China such as”Gas War Related Materials” and”Gas War Related Materials II”, and they also recorded systematically and in detail the Japanese invasion of China. The fact that chemical weapons were imported, stored, and used in China.
At the end of 1941, the Japanese base camp supplied at least 450,000 poisonous artillery shells, 7,700 poison aerial bombs, about 1 million poison smoke pipes, and 68 tons of bulk poison to the Japanese troops on the Chinese battlefield. After 1941, they continued to supply China with A large number of chemical weapons were supplied on the battlefield, the total number reached millions. The document also described the command of the then Japanese Chief of Staff, Miyinin Miyazai, requiring all combat troops to”mix with smoke screens as much as possible when using chemical weapons, and to conceal the fact that the poison gas was used strictly and not to leave traces.”
From
According to the available data, there are basically three situations in which the Japanese army used biological and chemical weapons during the war of aggression against China:First, the use of biological and chemical weapons as a means to achieve military objectives in large-scale battles. Such as the Wuhan battle in 1938,
The Yichang battle in 1940 and so on. Due to the relatively large scale of this campaign, the Japanese army has plans to use biological and chemical weapons, and even conduct biological and chemical weapons experiments in combat, so there are more detailed records, including the types and quantities of biological and chemical weapons that are prepared and actually used. Second, in general operations or in smaller-scale battles, the Japanese army uses chemical weapons flexibly according to the situation. This situation is more complicated, and there are occasional records left, most of which are not specifically recorded. However, after the war, China and Japan have quite a lot of memories about the use of poisonous gas in the war. The Chinese information is concentrated in a collection of materials called”Bacteriological Warfare and Gas Warfare”; the Japanese testimony is published by the Chinese Returnees Contact Association. It is also reflected in the memories of war criminals. The third situation is the use of chemical weapons as a means of persecution against civilians. When the Japanese army swept the areas controlled by the anti-Japanese forces at that time, they often used chemical weapons to attack peaceful residents hiding in tunnels. This is recorded in Japanese documents.

Infinite damage from biochemical warfare
day
After the defeat of this war, in order to cover up the crimes committed in China, the Japanese army secretly buried or discarded a large number of unused chemical weapons that were too late to take away in dense mountain forests, rivers and lakes, seaport beaches, and even residential areas. Among them, the three northeastern provinces are Japan has left China in the hardest hit area of ​​chemical weapons. According to relevant records from the Archives of Jilin Province, in the early days of liberation, there were more than 800 people in the Dunhua area of ​​Jilin Province during the process of cleaning up Japanese chemical weapons left in China
poison.
in
For a long time in the past, the Japanese government did not recognize the large number of chemical weapons abandoned in China. Until the end of the 1980s, international negotiations on the prohibition of chemical weapons entered a substantive stage.
The government has begun to solve the problem of Japanese chemical weapons left in China. The relevant military departments have also collected historical data and conducted field investigations to understand and master the burial of a large number of Japanese chemical weapons left in China. After many arduous diplomatic negotiations, in the face of indisputable facts, the Japanese side had to admit that these evidences buried for decades were chemical weapons abandoned by the Japanese army when they were defeated.
Since then, chemical weapons left by Japan in China have been discovered in more than 90 locations in 18 provinces, municipalities, and autonomous regions.
Since the Japanese side has not provided China with information on the specific locations and quantities of the chemical weapons left by Japan in China, the poisonous damage caused by the chemical weapons left by Japan in China continues for a long time.
In August 2003, 42 people in Qiqihar City, Heilongjiang Province were poisoned and 1 person died; in June 2004, 2 children in Lianhuapao Forest Farm in Dunhua City, Jilin Province were poisoned; in June 2005, 3 residents in Guangzhou City, Guangdong Province were poisoned; 2005 In August, a chemical weapon poisoning incident in China left by Japan in Ji’an City, Jilin Province, caused 1 resident to be poisoned; in August 2009, 5 people in Tianjin were poisoned; in November 2013, Lingang, Binhai New District, Tianjin
A large number of waste artillery shells were discovered during the construction of a wharf in the economic zone. After more than four months of excavation and identification operations by China and Japan, more than 1,000 chemical weapons left by Japan in China were found, which seriously affected the construction of the wharf; February 2014 On the 20th, a warehouse in Xinghualing District, Taiyuan City, Shanxi Province, found several Japanese chemical weapons left in China during construction. Afterwards, China and Japan conducted investigations into the buried Japanese chemical weapons left in China.
Industry, excavation and recycling work has been ongoing and has not yet ended.
according to
Incomplete statistics show that in the 70 years after the war, more than 2,000 people have been injured by the chemical weapons left by Japan in China, and the injuries caused by these chemical agents to the victims cannot be cured for life. And those not yet
The discovered chemical weapons left by Japan in China have been buried in the ground for more than 70 years, and they are severely corroded, still seriously threatening the lives of the Chinese people and the safety of the environment. Its processing and destruction are more than the processing and destruction of existing stockpiles of chemical weapons.
Destruction is more difficult and more dangerous.
Analytical science can bring great improvements to our lives, and at the same time, the malicious use of science and technology can also bring us great trauma. History reminds us:Use science and technology carefully and put your ability in a cage!
