POLYCYCLIC AROMATIC HYDROCARBONS

POLYCYCLIC AROMATIC HYDROCARBONS

POLYCYCLIC AROMATIC HYDROCARBONS What Are They? PAHs are a group of chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances. PAHs can be formed through natural processes or those related to human activities.
