BACKGROUND

In metallurgy, machinery, electronics, chemical industry, mining, transportation, construction and military industry, some toxic substances are often used or produced in the production process. Industrial poisons often exist in the air of production sites in the form of smoke, dust, fog, gas or vapor, and enter the human body through respiratory tract, digestive tract, skin or mucous membrane. Poisoning caused by respiratory tract is more common.
