title: chemical hazards to the human body, health should not be underestimated

description: chemical industry in industrial production occupies an important position, but at the same time also caused a great threat to our health. Through scientific data, facts and cases, this paper comprehensively analyzes the harm of chemical industry to human body, and focuses on the degree and source of chemical hazards and how to prevent chemical pollution, hoping to arouse everyone's attention and concern.

chemical industry refers to the transformation of raw materials into required products through chemical reactions or other manufacturing processes, including plastics, rubber, fertilizers, pesticides, fuels, etc. The wide application of chemical industry has brought huge economic benefits, but also brought great harm to the environment and human body. The harm of chemical industry to human body is mainly analyzed from the following aspects:

1. chemical pollution

waste water, waste gas and waste residue produced in the process of chemical production contain a large number of organic matter and heavy metals and other toxic and harmful substances, that is, chemical pollutants. These pollutants can be produced in production, storage, transportation and other links and released into the environment, and eventually enter our body. Long-term exposure and ingestion of these pollutants can lead to a variety of diseases, such as childhood leukemia, asthma, skin diseases, lung cancer, gastroenteritis and so on.

2. safety accident

Because the waste gas, waste liquid, waste residue and other substances involved in the chemical production process are often toxic and harmful, and high temperature, high pressure and other processes are often used, once a safety accident occurs, it will not only cause personal casualties, but also Lead to environmental pollution and material loss. For example, the explosion of Jiujiang Sunshine Chemical Plant in November 2005 caused serious casualties and environmental pollution.

3. food contamination

Because the chemical industry provides many additives and auxiliaries to the food processing industry, these additives and auxiliaries also bring great food safety risks. Chemical raw materials such as Sudan red and plasticizer have attracted wide attention because they are added to food. Chemical substances in food are very serious for our health problems. Long-term consumption can lead to various diseases, such as liver cirrhosis, brain lesions, cancer and so on. How do

prevent chemical pollution?

1. reduce the use of chemical raw materials

processing industry to reduce the use of chemical raw materials as much as possible, the development of renewable energy and new materials, the promotion of green chemical industry, reduce environmental pollution and human harm.

2. scientific treatment of chemical waste

For the waste generated, it is necessary to choose scientific and reliable treatment measures, such as recycling, biological treatment, etc., to greatly reduce the harm and pollution of waste to the environment.

3. to strengthen safety management

adhere to the "safety first" principle, strengthen safety training, improve the industry supervision system, to avoid the occurrence of safety accidents.

conclusion

chemical production is of great significance to economic development, but in this process, the harm of chemical industry to the environment and human health can not be ignored. Chemical pollution is constantly expanding, we should be fully aware of the serious consequences of chemical pollution, take effective measures to prevent and control, for human health and living environment to create a better tomorrow.
