BP oil spill dispersants concern Nova Scotia environmentalist

I really don't know what to make of this. On the one hand, environmentalists (especially "lone wolves") have a reputation for opposing things without having a viable alternative. On the other hand, there appears to be some evidence that "safer than dish soap" is not quite the bottom line.

So how do the risks compare? Is the solution more dangerous than the problem? I don't know. Are there currently other viable alternatives? Are there possible alternatives in the pipe?


Scientists at the Autonomous University of Aguascalientes in Mexico and the Georgia Institute of Technology now say Corexit 9500A is far more harmful than previously thought to a key dweller of those sub-surface depths.

An Environment Canada study states the dispersant is 27 times safer than common dish soap, but some say that figure is dangerously misleading. The study also states that five of Corexit’s 57 ingredients are linked to cancer and can pose “high and immediate human health hazards.”
