Boiofilm organic gas mainly comes from the petroleum, the chemical industry in the production process emissions.It has the characteristic that the organic matter content of ups and downs, with combustible, have a certain toxicity and there will be some odor.Chlorofluorocarbon emissions will cause the destruction of the ozone layer.Petrochemical production process and storage equipment,printing and other related to petroleum and chemical industry,the use of organic solvents.,Petroleum products for a variety of transportation fuels all above these will cause organic gas.【1】
The main components of organic waste are formaldehyde,acetone,acetic acid,ethyl -ester,additive and other organic gases containing carbon and oxygen and so on .
Organic gas damage plant leaf tissue and destroy the ozone layer,For the harm to human body is reflected in many aspects.Benzene is highly toxic solvents,even small amounts can cause long-term damage to the human body,it can accumulate in the bone marrow and the nervous system,damage hematopoietic tissue and nervous system,cause neurological disorders, reduce the amount of white blood cells in the blood, platelet,worse is suffering from leukemia.PAH and organic compounds have strong carcinogenesis.Benzoic acid can make the protein in a cell deformation or solidification, the systemic poisoning.Nitriles can cause breathing difficulties, can cause suffocation seriously, loss of consciousness until death.Glycol ether solvent in the human body can be formed after the metabolism o
