Organochlorine pesticides (OCPs) such as DDT and DDE have been detected in the surface 0.2m of Vertisols in the lower Namoi Valley of north western New South Wales, Australia even though they have not been applied to crops since 1982. However, their presence in the deeper soil horizons has not been investigated. The objective of this study was to determine if OCPs were present to a depth of 1.2...

In the present study, endosulfan degrading capability of four bacterial monocultures (RCE-2, GCE-4, GCE-5 and JCE-4) and two bacterial mixed-cultures (GCE345 and GCC134) was investigated in terms of treatment duration and culture volume, using soil slurry medium. Among the bacterial mono-cultures, JCE-4 was found to be most efficient with 16, 33, 60 and 65% of endosulfan (α + β-isomers) degrada...

Five species of macroalgae, namely Sargassum wightii, Padina tetrastromatica, Ulva lactuca, Caulerpa racemosa and Gracilaria edulis collected from three sampling sites, viz. Harbour Beach (site 1), Tharuvaikkulam 2) Hare Island 3), situated along the Thoothukudi region Gulf Mannar were analysed for 17 organochlorine pesticides (OCPs) by gas chromatography-mass spectrometry (GC-MS) to assess the...

Climate and soil conditions in South Florida along with an extensive canal system facilitate movement of agricultural pesticides into surface waters. In a two-year study (2002-2004) of the currently used pesticides in South Florida, atrazine, endosulfan, metolachlor, chlorpyrifos, and chlorothalonil were the most frequently detected in the canals and in Biscayne Bay, with average concentrations...

Agricultural intensification in sub-Saharan African countries has significantly increased pesticide applications. Information on residues and their transport groundwater streams is needed to properly manage reduce any harm the ecosystem environment. This information lacking volcanic soils of Ethiopian highlands. Therefore, this study was conducted assess concentrations ground surface water risk...

an extraction method based on matrix solid phase dispersion (mspd) and high performance liquid chromatography with uv detection for quantification of two widely used pesticides (malathion and α-endosulfan) in khazar rice from north of iran were investigated. the ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...

Cardiovascular disease is one of the most significant causes of mortality in humans and animals, and its etiology is usually unknown. The aim of this study was to investigate the cardiac pathology of endosulfan toxicity and the protective effect of vitamin C in rabbits. Twenty-four rabbits were divided into 4 groups: (1) the END group was given a daily sublethal dose of endosulfan in corn oil b...

This paper documents levels of organochlorine pesticides (OCs) in coastal surface sediments from selected reference sites on the northern Atlantic Spanish coast. One hundred eight samples covering three estuaries in the Cantabrian Coast were sampled in 2006 and analyzed in the finer fraction (<63 μm) for 19 OCs by gas chromatography with electron capture detector after confirmation by mass spec...

Endosulfan has an organochlorine pesticide. It may impair the normal embryonic development and disrupt normal reproductive functions in adulthood. Experiments were conducted on swiss albino mice (Mus musculus) under controlled physical conditions of temperature, ventilation and cleaning. The experiment was conducted in polypropylene cages. Cages of two sizes, (a) small cage=26×19×13 cm and (b) ...

Aquatic birds are often used as a health indicator of the marine ecosystem. African penguins living in the zoo make good research material as they form a link between the marine and the terrestrial ecosystem in terms of xenobiotic circulation. Tests were performed on whole herring-the food of the penguins-as well as on bird muscle, liver, brain, eggs, feathers and guano in order to determine to...
