The Five Major Causes of Environmental Pollution

Formaldehyde has a strong odor. Artificial boards use adhesives and contain formaldehyde. Inhaling high concentrations of formaldehyde can cause severe irritation to the respiratory tract. Direct contact with formaldehyde on the skin can cause dermatitis. Frequent inhalation of formaldehyde can cause chronic poisoning.

Benzene is a colorless liquid with a unique aromatic odor. Long term inhalation leads to aplastic anemia.

TVOC refers to volatile organic compounds. Mainly sourced from coatings, adhesives, etc. May cause symptoms such as dizziness, headache, drowsiness, weakness, and chest tightness.

Ammonia is highly soluble in water and has strong irritation to the eyes, throat, and upper respiratory tract. Long term exposure to low concentrations of ammonia can cause pharyngitis, hoarseness, and pulmonary edema.

Radon is a radioactive inert gas that is colorless and odorless. It exists in cement and sand, and its pollution is second only to smoking, listed as the second leading cause of lung cancer.

The TVOC analysis solution for indoor air pollutant detection is based on the requirements of the "Code for Indoor Environmental Pollution Control of Civil Building Engineering" issued by the Ministry of Construction. It uses gas chromatography to quantitatively detect the content of TVOC and methane non methane total hydrocarbons in indoor air pollution detection and benzene environment.
