The problem, explains Hodson, is that the dispersed cloud of microscopic oil droplets allows the PAHs to contaminate a volume of water 100–1,000 times greater than if the oil were confined to a floating surface slick. This hugely increases the exposure of wildlife to the dispersed oil. …Worse, the toxic constituents of oil hang around longer than other components, another speaker told the meeting. "This idea that there's an oil biodegradation rate doesn't hold,"... Alkanes, the simple hydrocarbons that comprise the bulk of oil, are degraded more readily than the PAHs, he points out.
As the Press Register notes:"These chemicals, these are PAHs that are carcinogenic. "There's no low-dose level that's acceptable to eat."…
