Do polycyclic aromatic hydrocarbons cause cancer?
Polycyclic aromatic hydrocarbon
PAHs have been linked to skin, lung, bladder, liver, and stomach cancers in well-established animal model studies.[52] Specific compounds classified by various agencies as possible or probable human carcinogens are identified in the section "Regulation and Oversight" below.
Oil tanker
Oil spills have devastating effects on the environment. Crude oil contains polycyclic aromatic hydrocarbons (PAHs) which are very difficult to clean up, and last for years in the sediment and marine environment. Marine species constantly exposed to PAHs can exhibit developmental problems, susceptibility to disease, and abnormal reproductive cycles.
