The Organochlorine Pesticides Residue Levels in Karun River Water

BACKGROUND The organochlorine pesticides (OCPs) are among the most commonly used in water streams around the world. Most of these contaminants are highly hydrophobic and persist in sediments of rivers and lakes. Studies have suggested that OCPs may affect the normal function of the human and wildlife endocrine systems. OBJECTIVES The aim of this study is to determine the concentrations of sel...

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...

Polychlorinated biphenyls, dioxins, furans, and organochlorine pesticides in belted kingfisher eggs from the upper Hudson River basin, New York, USA.

Nesting belted kingfishers (hereafter kingfishers, Ceryle alcyon) were studied on the Hudson River near Fort Edward south to New Baltimore (NY, USA) and three nearby river drainages in 2004. Concentrations of 28 organochlorine pesticides, 160 polychlorinated biphenyl (PCB) congeners, and 17 dioxin and furan (PCDD-F) congeners were quantified in kingfisher eggs. The pattern of organochlorine pes...

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...
