Description
Polycyclic aromatic hydrocarbons are aromatic hydrocarbons containing two or more benzene rings, referred to as PAHs. There are two main combinations of them, one is non-viscous ring type, which includes biphenyls, biphenyls and polyphenyls; The other is the thick ring type, in which two carbon atoms are shared by two benzene rings.
The sources of PAHs can be divided into natural sources and man-made sources. The natural sources are mainly from the biosynthesis process of terrestrial and aquatic plants and microorganisms. In addition, there are also PAHs in natural fires of forests and grasslands, volcanic emissions and from fossil fuels, lignin and sediment. Anthropogenic sources are mainly formed by the incomplete combustion or pyrolysis of various fossil fuels (such as coal, oil and natural gas, etc.), wood, paper, and other hydrocarbon containing compounds under reductive conditions.
Due to its toxicity, genotoxicity, mutability and carcinogenicity, PAHs can cause a variety of hazards to the human body, such as damage to the respiratory system, circulatory system, nervous system, liver and kidney. It is recognized as a major organic pollutant affecting human health.
