Several new studies of air and water near the site of the Deepwater Horizon oil spill conclude that cleanup workers may have escaped harm from one of the most worrisome groups of potentially toxic substances in the oil, according to an article in Chemical & Engineering News (CEN), ACS's weekly news magazine. But it cites concerns that another group of potentially harmful chemicals did escape from the water and could create a health hazard for cleanup workers. The article, by C&EN...

SAN FRANCISCO, Sept. 2, 2011 /PRNewswire/ -- A detailed analysis of air quality samples taken in the Gulf of Mexico in the weeks and months following the Deepwater Horizon oil spill last year finds no evidence that off-shore cleanup workers there faced health risks from exposure to certain volatile organic chemicals, including benzene. The independent study, undertaken by ChemRisk, a leading scientific consulting firm, found that exposure to airborne benzene, toluene, ethylbenzene and...

The mystery over what happened to the oil and gas released during last year's Gulf of Mexico oil spill has been partially solved, according to new research published this week in the Proceedings of the National Academy of Sciences. Researchers led by the Woods Hole Oceanographic Institution (WHOI) gathered oil and gas last year from the deep, 22-mile-long underwater oil plume as it escaped from the damaged wellhead of the Deepwater Horizon oil rig.   Using this data, they applied a...

By Killian, Paul F Bruell, Clifford J; Liang, Chenju; Marley, Michael C The persulfate anion (S^sub 2^O^sup 2-^^sub 8^) is a strong oxidant with a redox potential of 2.01 V. However, when mixed with iron (II), it is capable of forming the sulfate radical (SO^sup - ^^sub 4^sup .^^) that has an even higher redox potential (E[degrees] = 2.6 V). In these studies the sulfate radical was investigated to determine if it was a feasible oxidant for the destruction of BTEX and PAH compounds found in...
