There are many kinds of industrial waste gases, which may cause different degrees of harm. The source and editor will briefly introduce the types of exhaust gases and their hazards today.
Waste gas refers to the toxic and harmful gases emitted by human beings in production and life. In particular, chemical plants, steel plants, pharmaceutical plants, coking plants and oil refineries, as well as the production of domestic waste gas brought by human life. The exhaust gas has a strong smell, which seriously pollutes the environment and affects human health.

The exhaust gas has a strong smell, which seriously pollutes the environment and affects human health.
Waste gas contains a variety of pollutants with very complex physical and chemical properties and different toxicity. The exhaust gas generated by fuel combustion contains sulfur dioxide, nitrogen oxides (NOx), hydrocarbons, etc. Due to different raw materials and processes used in industrial production, various harmful gases and solid wastes will be discharged, including heavy metals, salts, radioactive substances and other components; The tail gas from automobiles contains lead, benzene, phenol and other hydrocarbons. Air pollution is one of the most serious environmental problems in the world. China's Environmental Protection Law clearly stipulates the exhaust emission standards for various factories and mines. Some of the waste gas is recycled and reprocessed into usable products.
Industrial waste gas discharged by various production enterprises is an important source of air pollutants. After reaching the standard, if a large amount of industrial waste gas is discharged into the atmosphere, it will inevitably reduce the quality of the atmospheric environment, seriously endanger human health, and cause huge losses to the national economy. Toxic and harmful substances in industrial waste gas can enter human body through respiratory tract and skin. Long term low concentration or short term high concentration exposure will cause temporary and sexual damage to human respiration, blood, liver and other systems and organs, especially benzore aromatics will cause direct carcinogenesis to human body and cause great attention to human beings.
Industrial waste gas includes organic waste gas and inorganic waste gas. Organic waste gas mainly includes various hydrocarbons, alcohols, aldehydes, acids, ketones and amines. Inorganic waste gas mainly includes sulfur oxides, nitrogen oxides, carbon oxides, halogens and their compounds.
