PAHs (Polycyclic Aromatic Hydrocarbons)

1. Introduction
PAHs are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances.They can also be found in substances such as crude oil, coal, creosote, and road / roofing tar. non-purified mineral oil plastizer for rubber, mould release agent oil, glue,dyestuff/pigment, solvent, some raw material of intermediate of some chemicals.

2. PAHs list
PAHs are a group of chemicals, with >100group and 10,000substances, and 16 of PAHs were banned because of the carcinogenous suspicion.
