OBJECTIVES In this study we evaluated the concentrations of selected persistent organic pollutants in a sample of first-time pregnant females residing in the United States and assessed differences in these concentrations in all pregnant females during gestation. METHODS We reviewed demographic and laboratory data for pregnant females participating in the National Health and Nutrition Examinat...

The ever increasing pile-up of electronic waste in dumping sites, especially in developing countries such as China, Pakistan, India and several African countries, might have caused a significant alteration in the microbial community of the contaminated sites. This change in the microbial population may have significant impact to the soil ecology function. The major pollutants of electronic wast...

From semipermeable membrane devices (SPMDs) placed in five Mississippi Delta streams in 1996 and 1997, the persistent organic pollutants (POPs) aldrin, chlordane, DCPA, DDT, dieldrin, endrin, heptachlor, mirex, nonachlor, and toxaphene were detected. In addition, the insecticides chlorpyriphos, endosulfan, and hexachlorocyclohexanes were detected. Two low-solubility herbicides not detected comm...

The precautionary principle has been central to many of the debates concerning the appropriate approach to the threat posed by endocrine active substances (EASs). This newly emerging principle has been applied to issues as diverse as persistent organic pollutants and the European trade barrier on beef from hormone-treated cattle.

We report herein the selective array-based detection of 30 persistent organic pollutants via cyclodextrin-promoted energy transfer. The use of three fluorophores enabled the development of an array that classified 30 analytes with 100% accuracy and identified unknown analytes with 96% accuracy, as well as identifying 92% of analytes in urine.

Existing and emerging persistent organic pollutants (POPs) constitute great threats to human health cause economic loss. The persistence of these chemicals made it necessary develop proper mitigation...
