Many classes of compounds including organochlorine pesticides such as DDT, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are considered persistent organic pollutants or POPs. These[r]

Styrene can be found in air, soil, and water after release from the manufacture, use, and disposal of styrene-based products. It evaporates from shallow soils and surface water. Styrene that remains in soil or water can be broken down by bacteria. Styrene is not usually f[r]
