One. Is the odor of paint harmful to the body?
When painting, if proper protective measures are not taken, inhaling the strong odor of paint can be harmful to human health.
Two. What are the harms of paints?
The paints primarily contain toxic substances such as formaldehyde, benzene, ammonia, and TVOC. Formaldehyde can cause nasopharyngeal cancer, benzene can induce leukemia, ammonia can cause pulmonary edema and acute respiratory distress syndrome, and TVOC (Total Volatile Organic Compounds) can cause symptoms such as loss of appetite and nausea.
1、Formaldehyde
Formaldehyde is a colorless, volatile, and irritating gas. Various synthetic wood panels, as well as adhesives, interior paints, wallpaper, and carpets, are major sources of formaldehyde. Formaldehyde poses long-term, insidious, and hidden hazards. Its release period can last up to 3-15 years. Formaldehyde can be absorbed through the respiratory system, and prolonged exposure can lead to serious diseases such as nasopharyngeal cancer and laryngeal cancer.
2、 Benzene
Benzene is a colorless gas with a distinct odor. It is primarily found in various paints and adhesives. Inhaling benzene and benzene-containing substances can cause central nervous system depression, suppress blood cell production, leading to a decrease in red blood cells, white blood cells, and platelets, and increasing the risk of aplastic anemia. It can also cause menstrual irregularities and congenital defects in fetuses.
3、Ammonia
Ammonia is primarily derived from concrete shrinkage-reducing agents, high-alkali concrete expanding agents, and early-strength agents in concrete walls. Ammonia has a very high solubility and can irritate and corrode the upper respiratory tract, weakening the body's resistance to disease. Prolonged exposure to ammonia may cause skin pigmentation or finger ulceration; short-term inhalation of large amounts of ammonia gas can cause tearing, throat pain, hoarseness, cough, bloody sputum, chest tightness, and difficulty breathing, accompanied by dizziness, headache, nausea, vomiting, and fatigue. In severe cases, it can lead to pulmonary edema and acute respiratory distress syndrome (ARDS).
4、Total Volatile Organic Compounds (TVOCs)
VOC stands for Volatile Organic Compound. While the concentration of each component in VOC is low, the variety is high, and the presence and interaction of multiple VOCs increase the hazard level. The main components of TVOC include benzene, toluene, butyl acetate, ethylbenzene, styrene, and nonanol, etc. Indoor building materials and paint decoration materials are the main sources of TVOC in the air. TVOC can disrupt the body's immune system, affect the function of the central nervous system, causing symptoms such as dizziness, headache, drowsiness, weakness, and chest tightness. It can also affect the digestive system, causing loss of appetite and nausea. In severe cases, it can damage the liver and hematopoietic system, and even cause death.
