"Natural" remediation of DDT, PCBs debated
Article Abstract:
The issue of natural remediation of organic pollutants such as DDT and PCBs is still being debated, with new claims about the benefits of microbial action. Research states that chlorinated compounds are broken down with the aid naturally-occurring organisms in sediments is important because it suggests that problems from DDT may not persist forever. However, Fred Schauffler of the EPA, disclaim the significance of new findings as he said that DDT compounds deposited for over 20 years are still present in surface.

Atrazine not an ecological risk, study says
Article Abstract:
An ecological risk assessment funded by major atrazine manufacturer Ciba-Geigy Corp. showed that atrazine, a widely used agricultural herbicide, does not pose considerable risks to aquatic environments. The assessment was conduced using best-practice recommendations and is being lauded as model assessment. However, several sectors point out that ecological risk assessment is still evolving, so the environmental effects of atrazine should not be undermined.

Endocrine disrupter research strategy completed by EPA
Article Abstract:
EPA's Office of Research and Development has launched a study to increase the understanding on the impacts of dioxin, popularly known as Agent Orange, on the environment and human health. The research will focus on determining the effects of dioxin on the endocrine and reproductive systems through the use of a dose-response model.
