Industrial waste gas emitted by various production enterprises is an important source of air pollutants. If a large amount of industrial waste gas is discharged into the atmosphere without being treated to meet the standards, it will inevitably reduce the quality of the atmospheric environment, cause serious harm to human health, and cause huge losses to the national economy. Toxic and harmful substances in industrial waste gas can enter the human body through the respiratory tract and skin. Long-term low-concentration or short-term high-concentration exposure can cause temporary and permanent lesions in the human respiratory, blood, liver and other systems and organs.
