not a polycyclic aromatic hydrocarbon (PAH) problem. The media keeps saying this over and over, but the media does not know PAHs or crude oil.

PAHs are a chronic toxin causing cancers through long-term exposure. They do have some moderately bad toxicity due to direct exposure. But there are lots and lots of other compounds in crude oil that are immediate and acute hazards. First, oil is hydrophobic and lipophilic. It clings to plants and animals due to its viscous nature and that hydrophobicity. There are saturated hydrocarbons that disrupt metabolism and other bodily functions because they disrupt the absorption and adsorption in the body that transfers nutrients and gets rid of toxic waste.

There are carboxylic acids, phenols, amines, and lots of other polar compounds that react and bind to chemical sites important to a body working right. Some of these compounds are poisonours directly and acutely. Sulfur compounds react and bind iup a lot of chemical functional groups that make those groups no longer work the way they ought to. Et cetera, et cetera.

Yes, over the years, fish and birds will get cancewrous growths, but those are the least of a long list of worries. The animals will die from ingestion of all the other things in oil well before the cancers get serious.
