After a lengthy scientific review, the United States last week decided to ban the use of endosulfan, an inexpensive organochlorine pesticide that builds up in the environment. The U.S. Environmental Protection Agency ruled that the compound

Persistent organic pollutants (POPs) are toxic chemicals that resist degradation and bioaccumulate. Despite attempts to limit the use and distribution of these chemicals, they are still widely detected in the environment. Schecter et al.

The goal of this study was to identify commercial chemicals that might be persistent and bioaccumulative (P&B) and that were not being considered in current Great Lakes, North American, and Arctic contaminant measurement programs.

How do climate fluctuations affect DDT and hexachlorocyclohexane (HCH) distribution in the global scale? In this study, the interactions between climate variations and depositions of DDT and HCH in ice cores from Mt. Everest (the Tibetan Plateau), Mt. Muztagata (the eastern Pamirs) and the Rocky Mountains were investigated. All data regarding DDT/HCH deposition were obtained from the published results. Concentrations of DDT and HCH in an ice core from Mt. Everest were associated with the El Nino-Southern Oscillation. Concentrations of DDT in an ice core from Mt.

This study evaluated the associations of body burden levels of dioxins and related compounds with the prevalence of metabolic syndrome among the general population in Japan.
