Polycyclic Aromatic Hydrocarbons Testing

Name: Polycyclic Aromatic Hydrocarbons Testing
Rating: 5 (288 reviews)

Polycyclic aromatic hydrocarbons refer to aromatic hydrocarbons containing two or more benzene rings, abbreviated as PAHs. They mainly have two combination methods. One is the non - fused - ring type, which includes biphenyl and polyphenyls, as well as polybenzene - substituted alkanes. The other is the fused - ring type, where two carbon atoms are shared by two benzene rings.

Service Background

The sources of polycyclic aromatic hydrocarbons are divided into natural sources and anthropogenic sources. Natural sources mainly come from the biosynthesis processes of terrestrial and aquatic plants and microorganisms. In addition, polycyclic aromatic hydrocarbons are also present in natural fires in forests and grasslands, volcanic eruptions, fossil fuels, lignin, and sediment. Anthropogenic sources are mainly formed by the incomplete combustion or pyrolysis under reducing conditions of various fossil fuels (such as coal, oil, and natural gas), wood, paper, and other hydrocarbons - containing compounds.

Due to their toxicity, genotoxicity, mutagenicity, and carcinogenicity, PAHs can cause various harms to the human body, such as damage to the respiratory system, circulatory system, and nervous system, as well as damage to the liver and kidneys. They are recognized as major organic pollutants affecting human health.
