In the present study, we determined levels of chlorinated pesticide residues in surface water samples collected from Charsadda district (KPK, Pakistan). SPME-GC-ECD with COMBI PAL CTC autosampler was used for extraction and analysis 20 organochlorine pesticides samples. For maximum efficiency SPME procedure, several parameters were studied, including desorption time fiber, solution pH, agitatio...
Mean 96-hr LCs0 values and standard deviations for the oligochaetes S. heringianus and L. hoffmeisteri exposed to endrin-contaminated sediment were 2,588 _ 1,974 txg/g dry weight sediment for 4 assays and 2,725 + 955 Cg/g for 2 assays, respectively. Mixed species testing data suggested that the toxicity to L. hoffrneisteri was reduced in the presence of S. heringianus, yet further testing is re...
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...
The paper concern is determination of eight pesticides in food products samples. The target compounds are: Lindane, Heptachlor, Aldrin, o,p-DDE, Dieldrin, Endrin, p,p’-DDT, and Methoxychlor. The compounds quantities were performed from chromatographic area obtained in full scan GC/MS mode after baseline separation and by comparation with surrogate internal standard area (Diphenylamine). The sam...
Like most of Madagascar's endemic primates, ring-tailed lemurs (Lemur catta) face a number of threats to their survival. Although habitat loss is of greatest concern, other anthropogenic factors including environmental contamination may also affect lemur health and survival. In this study, we examined ring-tailed lemurs from the Beza Mahafaly Special Reserve (BMSR), southern Madagascar for expo...
Many international efforts have been spent to eliminate and/or reduce the emissions and discharges of a wide range of pollutants that have persisted in the environment as well as living organisms [1]. These pollutants are known as a persistent organic pollutants (POPs). Contamination from POPs is a pervasive global problem that urgently demands a global solution [2]. These chemicals include org...
