POLYCYCLIC AROMATIC HYDROCARBONS

Polycyclic Aromatic Hydrocarbons (Polycyclic Aromatic Hydrocarbons PAHs) are volatile hydrocarbons produced when organic matter such as coal, petroleum, wood, tobacco, and organic polymer compounds are incompletely burned. They are important environmental and food pollutants. So far, more than 200 PAHs have been discovered, of which quite a few are carcinogenic, such as benzo[α]pyrene, benzo[α]anthracene, etc. PAHs are widely distributed in the environment and can be found in every corner of our lives. Any place where organic matter is processed, discarded, burned or used is likely to produce polycyclic aromatic hydrocarbons, such as oil refineries, coking plants, rubber plants, and thermal power plants that emit smoke and dust. In the exhaust gas emitted by various traffic vehicles, gas and Other heating facilities and even residents’ cooking smoke is medium. According to the analysis of the atmospheric composition of eight continents in the United States, the PAHs in the atmosphere in industrial areas are more than 10 times higher than in agricultural areas. Polycyclic aromatic hydrocarbon pollutants have become extremely important environmental pollutants. substance. PAHs is a highly carcinogenic substance. Now the German government mandates that the power tools sold in the German government must be tested to not contain excessive PAHs. Power tools that want to enter the German market must be tested by a professional inspection agency.
