The hazards of garbage can be classified into: the hazards of domestic garbage and the hazards of incinerating and treating garbage.

I. Hazards of Domestic Waste

Human and animal feces contain infectious bacteria and viruses.

⑵ Medical waste from medical institutions. There are a large number of chemical substances that are susceptible to viruses and difficult to degrade.

⑶ Construction and decoration waste. There are volatile chemical substances.

⑷ Light industrial waste. Most of them are non-biodegradable chemical materials, such as plastics, paints, etc.

(5) Electronic material waste produced by the electronics industry. It includes the main heavy metal components and hard-to-degrade glass fibers, plastics, etc. Heavy metals include lead, tin, zinc, silver, gold and other heavy metal materials that are harmful to human health.

(6) Chemical industry produced waste containing toxic and harmful substances. Volatile substances such as benzene.

Battery. It is an indispensable industrial product in people's lives. Its pollution is mainly reflected in heavy metals and chemical substances, including chemical components such as acids and alkalis, as well as materials that are difficult to degrade, such as plastics.

Domestic sewage from all aspects of the city and sewage discharged by industrial enterprises such as manufacturing.

A small amount of radioactive contaminants.

⑽ Other human domestic waste not listed.

Ii. Hazards of Incinerating Garbage

Incineration treatment can also cause environmental pollution and superficial long-term sexual harm, mainly including air pollution after the combustion of garbage. This type of pollution mainly includes:

Pollution from toxic and harmful substances produced during the high-temperature incineration of chemical products.

⑵ Pollution by toxic and harmful substances in the air (including sulfides, carbides and other substances).

⑶ The pollution of the environment caused by chemical waste generated by the automotive industry, as well as the severe pollution and low chronic pollution from diesel vehicle exhaust.

⑷ Pollution from other toxic and harmful substances produced when domestic waste is burned.

Despite the existence of high-tech dust removal and facilities for reducing the emission of toxic and harmful substances, there are still long-term emissions and accumulation of trace amounts of harmful substances, which can still cause chronic pathological damage to the Earth's organisms. However, due to the long-term accumulation of trace harmful substances in the body, chronic diseases keep worsening, making it difficult to diagnose the condition.

No matter how advanced modern technology is, the above two items cannot be completely purified. There will always be a certain amount of chronic and cumulative comprehensive harm to humans and living beings. The consequence it leads to is no different from chronic suicide of human beings.
