Distribution Profile of Chiral Organochlorine Pesticides in Ambient Air

Levels, Temporal-Spatial Variations, and Sources of Organochlorine Pesticides in Ambient Air of Lake Chaohu, China

The residual levels of OCPs in the gas phase and particle phase in Lake Chaohu, China, were measured using GC-MS from March 2010 to February 2011. The temporal-spatial variations and sources of OCPs were also analyzed. Twenty types of OCPs were detected in the gas phase with a total concentration of 484.8 ± 550.4 pg/m³. Endosulfan, DDTs and chlordane were the primary OCPs in the gas phase. The ...

Distribution of organochlorine pesticides in a sediment profile of the Pearl River estuary.

The global distribution of PCBs and organochlorine pesticides in butter.

In this study we explored the use of butter as a sampling matrix to reflect the regional and global scale distribution of PCBs and selected organochlorine pesticides/metabolites in air. This was because persistent organic pollutants (POPs) concentrate in dairy fats, where concentrations are controlled by feed intake (primarily from pasture/silage), which is in turn primarily controlled by atmos...

Organochlorine pesticides in gallstones.

A method is described for the determination of organochlorine pesticide residues in human gallstones. The difficulty caused by the presence of large amounts of cholesterol in the stones is overcome by an acetylation step in the “clean-up” procedure, and the method finishes with identification and determination of the individual pesticides by gas-liquid chromatography. Results are given for 28 s...

Organochlorine pesticides in danish milk

Introduction Organochlorine pesticides and PCB congeners are persistent organic compounds found in the environment. Because of their stability and tendency to accumulate in fat they can enter the food chain and therefore be found in cow milk. As these chemicals are banned in most countries, it is expected that the compounds can still be found in cow milk due to environmental contamination of th...
