Gulf oil dispersants don’t seem to disrupt marine life, say scientists

July 22nd, 2010 - 2:28 pm ICT by ANI  

Washington, July 22 (ANI): Scientists have claimed that eight of the most commonly used oil dispersants used to fight oil spills appear unlikely to act as endocrine disruptors - hormone-like substances that can interfere with reproduction, development, and other biological processes.

The tested dispersants also have relatively low cell toxicity, say scientists with the U. S. Environmental Protection Agency and the National Institutes of Health Chemical Genomics Center.

In their study, Richard Judson and colleagues found that none of the substances showed significant endocrine disruption activity and cytotoxicity until they were tested at concentrations above 10 parts per million.

However, they note that, “there are other routes by which chemicals can cause endocrine disruption, as well as other types of toxicity that have not been tested for here.”

Their findings appear in ACS’ semi-monthly journal Environmental Science & Technology. (ANI)
