Effect of temperature on the formation and degradation of polycyclic aromatic hydrocarbons

Polyaromatic hydrocarbons (PAHs) are a class of aromatic hydrocarbon compounds which are catagorised as pollutants with carcinogens, and mutagenic characteristics. Scientifically, incomplete combustion and petroleum compounds emission were proven as a major source of PAHs. Thermal degradation of PA...
