A polychlorinated biphenyl (PCB) and Polycyclic aromatic hydrocarbons (PAHs) ) are a class of chemicals that occur commercially & naturally from the source. Polychlorinated biphenyls (PCBs) are compounds derived from substitution of 1–10 hydrogen atoms of biphenyl by chlorine atoms. PCBs have been produced and used worldwide in large quantities for many years as transformer oils, metal-cutting oils, hydraulic oils, heat transfer fluids, additives in plastics, dyes, and carbonless copying paper.
Polycyclic aromatic hydrocarbons (PAHs) are occur naturally in coal, crude oil, and gasoline. PAHs are produced when coal, oil, gas, wood, garbage, and tobacco are burned. High-temperature cooking will form PAHs in meat and in other foods. Both the pollutant travel up the food chain through fish, mammals, birds.
