The concentrations of 16 pesticides residues (alpha BHC, gamma BHC (lindane), beta BHC, Heptachlor, Aldrin, Heptachlor Epoxide, Endosulfan I, Dieldrin, Endrin, Endosulfan II, 4, 4 DDT, Endosulfan Aldehyde, Endosulfan sulfate, Atrazine, Phosphomethylglycine and Carbofuran) in two fish species (Tilapia zilli and Clarias gariepinus) from selected rivers (Illushi, Owan and Ogbesse) in Edo State, Ni...

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 (...

Increases in non-Hodgkin's lymphoma (NHL) incidence and mortality rates during the past few decades remain largely unexplained. Studies suggest that organochlorine pesticides may contribute to an increased risk of NHL. In 1974, serum samples were obtained from 25,802 participants in the Campaign Against Cancer and Stroke in Washington County, Maryland (USA), and cryopreserved for future study. ...

Organochlorine insecticides and their degradation products contribute to toxicity in Chesapeake Bay, USA, sediments and affect the reproductive health of avian species in the region; however, little is known of atmospheric sources or temporal trends in concentrations of these chemicals. Weekly air (n = 265) and daily rain samples (n = 494) were collected over 2000 to 2003 from three locations i...

Aquatic organisms are good bio-indicators of the environmental health in freshwater lakes; Xenobiotics are foreign materials to the organisms’ body and do not occur naturally in nature. Xenobiotics accumulate in adipose tissues due to high affinity to fatty tissues. This paper reports the levels of Organochlorine pesticide (OCPs) residues, their metabolites and Polychlorinated Biphenyl (PCBs) c...

Using gas chromatography—electron capture detector protocol, pesticide residue levels on four common vegetables (cabbage, carrot, lettuce, and tomatoes) consumed in Ho Municipal, Ghana, were investigated. A total of 5 kg each the randomly sampled triplicate from three different markets. Organochlorine pesticides, including residues γ-HCH, δ-HCH, heptachlor, aldrin, p, p’-DDT, o, p’-DDT p’-DDE d...
