 were investigated for the presence and level of organochlorine pesticides (OCPs) (hexachlorobenzene CHCB), Hexachloroexthane (Pp’DDI), Aldrin, Trithralin, Heptachlor Epoxide, Eudrin, Merix, Endosulfanand Methoxychlor), using Hewlett-Packard (Hp 689) Gas Chromatography equipped with electron capture detector. Ocps were detected in all samples analysed, the total residue concentration was found to be highest in pepper (6.2650mg/kg), followed by tomatoes (5.7461mg/kg), spinach (5.0846mg/kg), Pumpkin leaf (4.5356mg/kg) and water leaf (3.3308mg/kg), respectively, while the average concentration of each OCPs residues were found to be (0.8678 mg/kg) for HCHs, (0.0012mg/kg) for HCB, (0.5764 mg/kg) for aldrin, (0.5310 mg/kg) for trifluralin, (0.1635 mg/kg) for heptachlor epoxide, (0.5046 mg/kg) for dieldrin, (0.8841 mg/kg) for endrin (0.3460 mg/kg) PP’DDT, (0.3847 mg/kg) for endosulfin and (0.0056mg/kg for methoxyclor. The OCPs residue consideration were below FAOs (2.50mg/kg) and WHO (200 mg/kg) maximum concentration limits.&picture=http://www.aascit.org/aascit/decorators/img/journal/980.jpg)

Sample of commercially soldpumpkin leaves, water leaves, pepper, tomatoes and spinach in Wukari (Taraba South) were investigated for the presence and level of organochlorine pesticides (OCPs) (hexachlorobenzene CHCB), Hexachloroexthane (Pp’DDI), Aldrin, Trithralin, Heptachlor Epoxide, Eudrin, Merix, Endosulfanand Methoxychlor), using Hewlett-Packard (Hp 689) Gas Chromatography equipped with electron capture detector.
