Some toxic substances in paint are harmful to the human body. The toxic substances in paint can be classified into solvents (formaldehyde, toluene, benzene, xylene, aldehydes, ketones, esters, ethers, aromatics, etc.) and heavy metals. (lead, chromium, mercury, cadmium, etc.) In general, the content of these substances in the brand paint is relatively low, and the environmental performance is relatively good.

Benzene can cause aplastic anemia resulting in leukemia. According to reports, the children's ** surveyed family living environment when they visited children with leukemia, and found that 90% of the small patients had been renovated within half a year before the diagnosis, and most of them were luxurious decoration. To this end, experts reminded parents that benzene and volatile organic compounds are recognized by the world medical community as carcinogenic substances. Children's respiratory volume is 50% higher than that of adults; children spend more time indoors than adults; children’s immunity is much lower than that of adults. These characteristics determine that children are more vulnerable to indoor environmental pollution than adults.

The proportion of serious diseases such as aplastic anemia, leukemia, tuberculosis, and pleurisy is also quite high. If people inhale the vapors of organic solvents for a long time, they will cause chronic poisoning. However, exposure to high concentrations of organic solvent vapors for a short period of time will also have the danger of being acutely poisoned. In industrial hygiene, the harm of organic solvents on the human body has a close relationship with the volatility of solvents. At room temperature, low volatile solvents do not pose a hazard in air. Other human hazards are related to the solvent's fat-soluble, reactive, containing impurities, the body's absorption of the way and way, the body's metabolic rate, accumulation, individual feeling and sensitivity, the length of exposure and so on. Most painters over ten years of service have symptoms of coughing, fatigue, headaches, chest tightness, and weakness.
