Chlorinated Pesticide Residues in Chicken Egg

Distribution of polychlorinated biphenyls and chlorinated pesticide residues in trout in the Sierra Nevada.

Organochlorine compounds are known to be atmospherically transported to long distances from their original sources. To understand the influence of California's Sierra Nevada range on the air transport and subsequent distribution pattern of some of these residues within the range, we have chosen salmonid fish as an indicator species. Fish were collected from 10 locations throughout the northern ...

Levels and distribution of chlorinated pesticide residues in water and sediments of Tarkwa Bay, Lagos Lagoon

Microlayer water, mixed layer water, epipellic and benthic sediments were collected from Tarkwa Bay end of Lagos Lagoon to analyse for chlorinated pesticide residues. Sampling was conducted between December 2008 and September 2009 during the dry and wet seasons to study effects of seasonal variation on the samples. Water samples were subjected to liquid-liquid extraction using dichloromethane w...

Occurrence of organochlorine pesticide residues in eggs, chicken and meat in Jordan.

Organochlorine pesticide (OCP) residues in 519 samples; comprising eggs, chicken and meat (lamb and beef), collected from Jordan were determined. All samples were analyzed for their residual contents of aldrin, dichlorodiphenyltrichloroethane and metabolites (DDTs), dieldrin, endosulfan isomers, endrin, hexachlorocyclohexane isomers (HCHs), heptachlor, heptachlor epoxide and hexachlorobenzene (...

Pesticide Residues in Bee Products

"The man has no divine right over the food. He must compete for this with weeds, diseases, insects and other organisms” (Grodner, 1996). With the above quote, Grodner clearly reflects the situation in the area production and processing of food. More than 10.000 species of insects and mites, 1.500 species of fungi and 600 plant species have been identified as harmful to agriculture (Grodner, 199...
