What are the world s top 10 pollution events?

Hello, the harm caused by the world's top ten pollution events to the earth is very serious, so that all mankind has been greatly affected, and the consequences are very bad, and should be resisted.

The eight major environmental pollution incidents are known as the eight major public pollution incidents, which are as follows:

1. Belgium.

Maas Valley smog incident.

From December 1 to 5, 1930, in the industrial area of the Maas Valley in Belgium, harmful exhaust gases (mainly sulfur dioxide) were discharged.

and dust has a comprehensive impact on human health, among which the toxic symptoms are coughing, tearing, nausea, vomiting, thousands of people have become ill in a week, nearly 60 people have died, and citizens have heart disease.

The mortality rate of patients with lung disease is increased, as is the mortality rate of domestic animals.

2. The Los Angeles smog incident in the United States.

From May to October 1943, the photochemical smoke produced by a large number of automobile exhaust gases in Los Angeles caused most residents to suffer from diseases such as red and swollen eyes, laryngitis, and respiratory diseases, and more than 400 people over the age of 65 died.

3. The Donora incident in the United States.

October 26-30, 1948, Pennsylvania, USA.

The sulfur dioxide and other oxides in the atmosphere of Donora Town interact with the atmospheric soot to produce sulfuric acid smoke, which seriously pollutes the atmosphere, and the residents of the city have fallen ill and 17 people have died within 4 days, among which the poisoning symptom is cough.

Vomiting, diarrhoea, sore throat.

4. The smog incident in London, England.

From December 5 to 8, 1952, more than 4,000 people died in five days in London, England, due to the formation of soot caused by coal burning in winter.

5. Minamata disease incident in Japan.

1953-1968, Kumamoto Prefecture, Japan.

In Minamata Bay, nearly 10,000 people in the central area suffered from neurological diseases, including 66 out of 283 patients with methylmercury poisoning, due to the consumption of fish, shrimp, shellfish and other aquatic animals contaminated by mercury-containing sewage in the bay.

6. Asthma in Yokkaichi, Japan.

Event. From 1955 to 1961, the city of Yokkaichi in Japan polluted the atmosphere due to the exhaust gases produced by petroleum processing and industrial fuels, which caused a sharp increase in the incidence of respiratory diseases among residents, especially the incidence of asthma.

7. Aichi Prefecture, Japan.

Rice bran oil incident.

In March 1963, in Aichi Prefecture, Japan, due to the poor management of the rice bran oil production industry, PCB contaminants were mixed into the rice bran oil, and after people ate the contaminated oil, more than 10,000 people were poisoned and hundreds of thousands of chickens died.

8. Toyama bone pain incident in Japan.

From 1955 to 1968, 258 people living in the Toyama Plain region of Japan died from "bone pain" caused by drinking cadmium-containing river water and eating cadmium-containing rice and other cadmium-containing foods.

The eight major environmental pollution incidents are known as the eight major public pollution incidents, which are as follows:

1. Smog incident in the Maas Valley, Belgium.

2. The Los Angeles smog incident in the United States.

3. The Donora incident in the United States.

4. The smog incident in London, England.

5. Minamata disease incident in Japan.

6. The asthma incident in Yokkaichi City, Japan.

7. Rice bran oil incident in Aichi Prefecture, Japan.

8. Toyama bone pain incident in Japan.

Chernobyl nuclear leak. Morning of April 27, 1986, former Soviet Union.

Now Ukraine. A nuclear leak accident occurred in a group of reactors at the Chernobyl nuclear power plant, causing a series of serious consequences.

Clouds with radioactive material drifted to Denmark and Norway with the wind.

Sweden and Finland.

and other countries, the radiation dose in the eastern coastal areas of Sweden exceeded normal by 100 times. The nuclear accident affected 10% of the wheat in Ukraine, and the livestock industry in the former Soviet Union and European countries suffered greatly due to water pollution.

The world's eight most famous environmental pollution incidents are: the Maas Valley smog incident in Belgium, the Donora town smog incident in the United States, the London smog incident, the Los Angeles photochemical smog incident in the United States, the Minamata disease incident in Japan, the Toyama bone pain incident in Japan, the asthma incident in Yokkaichi City, and the rice bran oil incident in Japan.

These eight major environmental pollution incidents are known as the Eight Major Public Pollution Incidents, also known as the Eight Major Environmental Hazards. The frequent occurrence of environmental pollution incidents in the world is due to the rise and development of modern chemical, smelting, automobile and other industries, resulting in the continuous increase in the emission of industrial waste gas, waste water and solid waste.

Industrial waste gas, waste water, and solid waste are the "three wastes" of industry, also known as "raw materials placed in the wrong place", and if they are used, they can improve environmental sanitation.
