Heavy metal elements

The solubles of heavy metal elements such as lead, cadmium and mercury are obviously harmful to the human body. Excessive lead can damage the nerves, hematopoietic function and reproductive system.

These pollutants mainly come from decoration materials such as solvent-based wood coatings, interior wall coatings, wood furniture, wallpaper, and PVC coiled flooring.



Ammonia is a colorless and strongly irritating gas. Because ammonia is easily soluble in water, it can absorb water in tissues, has a quick effect on the eyes, throat, and upper respiratory tract, and is highly irritating. It can cause poisoning through the skin and respiratory tract. Long-term exposure to low-concentration ammonia can cause pharyngitis and hoarseness; severe cases can cause throat edema, difficulty breathing, coma, shock, etc. Ammonia mainly comes from concrete additives used, especially antifreeze containing urea.
