Organochlorine pesticide residues in dried cocoa beans obtained from cocoa stores at Ondo and Ile-Ife, Southwestern Nigeria
Levels of organochlorine pesticides (OCPs) were determined in dried cocoa beans obtained from cocoa produce stores at Ondo and Ile-Ife, Southwestern Nigeria. Cocoa beans samples were sun dried to a constant weight, pulverized and soxhlet extracted with dichloromethane to obtain the OCPs. Qualitative identification and quantitative evaluation of the extracted OCPs after clean-up on silica gel we...
متن کاملDetermination of Organochlorine Pesticide Residues in Water, Sedime
In this study, the levels of organochlorine (OC) pesticide residues in Lake Parishan have been investigated using water, sediment and fish (Barbus brachycephalus caspius) samples as a case study to find out the extent of pesticide contamination and accumulation in the lake. Six OC pesticides namely DDT, DDE, Lindane, Endosulfan, Heptachlor and Chlordane were analyzed in four sites at four seaso...
متن کاملAssessment of organochlorine pesticide residues in soils and drinking water sources from cocoa farms in Ghana
Residues of organochlorine pesticides were determined in soils and drinking water sources in cocoa growing areas in Ghana. Soil samples analysed showed the presence of four organochlorine pesticide residues namely lindane (0.005-0.05 mg/kg), beta-HCH (<0.01-0.05 mg/kg), dieldrin (0.005-0.02 mg/kg), and p,p'-DDT (0.005-0.04 mg/kg), with dieldrin occurring most frequently. Similarly, organochlori...
متن کاملDetermination of organochlorine pesticide residues in the raw milk taken from milk collection centers in Urmia in 2020
Background and Objective: Milk is one of the most important components of human food. In recent decades, the continued use of pesticides has led to contamination of soil, water, air and milk and caused public concern in the community. Long-term exposure to pesticide residuals in the food chain can be harmful. Therefore, there is a need to control environmental conditions in order to improve its...
متن کاملDetermination of organochlorine pesticide residues in herbs by capillary gas chromatography
Objective. The capillary gas chromatographic method was introduced for determining organochlorine pesticide residues (OCPs) in traditional Chinese medicines: Gastrodia Tuber, Fructus Corni and Spica Prunellae. Methods. The organochlorine pesticides were extracted from herbs with mixed solvents (petroleum ether), cleaned up by concentrated HzSO4, and separated by capillary column with electron c...
