Even if the materials, called dispersants, are effective, BP has already bought up more than a third of the world’s supply. If the leak from 5,000 feet beneath the surface continues for weeks, or months, that stockpile could run out.
On Thursday BP began using the chemical compounds to dissolve the crude oil, both on the surface and deep below, deploying an estimated 100,000 gallons. Dispersing the oil is considered one of the best ways to protect birds and keep the slick from making landfall. But the dispersants contain harmful toxins of their own and can concentrate leftover oil toxins in the water, where they can kill fish and migrate great distances.
I just found an article on line regarding biomediation of oil slicks published in English by the Indian Coast Guard, written by one Dr. Pradeep Kumar, located at:
If India understands the critical importance of using bioremediation for oil spills, why doesn't BP and the US government?!?
That is more than a little scary, in terms of the long-term potential toxic effects of these dispersants.
