PAHs:

polycyclic aromatic hydrocarbons or poly-aromatic hydrocarbons - a chemical compound that contains more than one fused benzene ring. They are commonly found in petroleum fuels, coal products, and tar. PAHs contain BTX (BTEX) compounds which belong to the category of organic chemicals (so called volatile organic compounds – VOCs) whose composition makes it possible for them to evaporate under normal indoor atmospheric conditions of temperature and pressure. VOCs may contribute to the formation of ground-level ozone and photochemical smog.
