Indoor air pollution
there are five harmful gases of indoor air pollution ，they are
Radon gas（氡气）
Formaldehyde （甲醛）
Ethyl benzene （苯）
TVOC（Total Volatile Organic
compounds 总挥发性有机化合物）
Ammonia gas （氨气）.
Radon gas（氡气)
Radon is a radioactive inert gas, colorless and exists in the cement（水泥）, sand and gravel（沙石）,marble （大理石）
Damage :Radon pollution is the second lung cancer promoter after smoking .
urea formaldehyde （甲醛)
Has a strong smell of formaldehyde. It exists in the artificial timber where used adhesives（粘合剂）.
Damage : After the inhalation of high concentrations of formaldehyde, there will be a serious stimulus to the respiratory tract. Direct skin contact with formaldehyd can cause dermatitis. Regular inhaled a small amount of formaldehyde, can cause chronicpoisoning. Data shows that more than half of patients with childhood leukemia [lju:`ki:miə]白血病has luxurious decoration at home.
Ethyl benzene （苯）
Benzene is a colorless, liquid with special aroma.
Damage : Long-term inhalation of benzene can cause aplastic anemia(贫血).
TVOC
Mainly come from the coatings（涂料）adhesives
Damage ：
TVOC can cause dizziness, headac
