Marine toxicologist and Exxon Valdez survivor Riki Ott writes about Obama's Oilgate in this HuffPo post. Excerpt:
BP's latest pretend is that tropical storm Bonnie washed the oil away - or at least off the surface - so the company is busily laying off response crews and claiming damages were over-exaggerated......The official story emerging now from BP and most of the president's men - and now being echoed by some national media - is: the oil is gone; the danger is past and was exaggerated; the dispersants were effective in keeping oil from reaching the shore; the oil that does reach shore is mostly weathered and not toxic; and federal officials have found no unsafe levels of oil in air or water samples and no evidence of illness due to oil or dispersant use.
The dispersants used in BP's draconian experiment contain solvents such as petroleum distillates and 2-butoxyethanol. Solvents dissolve oil, grease, and rubber. Spill responders have told me that the hard rubber impellors in their engines and the soft rubber bushings on their outboard motor pumps are falling apart and need frequent replacement. They say the plastic corks used to float the absorbent booms during skimming operations dissolve after a week of use. They say the hard epoxy resin on and below the waterline of their fiberglass boats is also dissolving and chipping away. Divers have told me that they have had to replace the soft rubber o-rings on their gear after dives in the Gulf and that the oil-chemical stew eats its way into even the Hazmat dive suits.
