Detection of some organophosphrous compounds residues in nile fish markets of some villages of Kaliobia governorate

A total sixty samples Nile tilapia [Qreochromis niloticus] and Clarias garpinus [Thirty of each] collected from fish markets of some villages of Kaliobia governorate and subjected to fat extraction and determination of organophosphrous residue by gas chromatography. Organophosphrous residues including diazinon, chlorpyrifos-ethyl, Malathion, Methyl-parathion, ethyl parathyion and Ethion with an incidence from muscles of Tilapia nilotica were [33%, 6.7%, 20%, 12%, 12% and 3% respectively] and from Clarias garpinus were[50%, 6.7%, 16%, 10%, 12% and 3% respectively]. The obtained result revealed that the residues of diazinon came in the first rank followed other organophosphrous residue. Most residues detected within action limit for fish, however, residues of these pesticide were not detected in collected samples may be due to their percent in very trace amount or gave indicter for safety environment from different types of pollution

Detection of some pesticides residues in beef and mutton meat in Menofia governorate

A total one hundred and sixty samples of beef and Mutton meat [eighty of each]. Collected from butcher's shops in four centers of Menofia governorate [Kausina, Menouf, Ashmoun and Shebin Elkom]. Twenty samples of each center were collected from each center and subjected to fat extraction and determination of some organo chlorine pesticide residues by G.C. [Gas chromatography]. Organochlorine residues including total DDT, [HCH] alpha-hexachlorocyclohexan Hexachlorobenzene [HCB], aldrin, dieldrin, endrine, toxaphene and heptachlorepoxide with an incidence from beef meat were [12.5%, 10%, 10%, 10%, 10%12.5%, 0% and 0%] respectively. While the residue levels were detected in Mutton meat with an incidence [25%, and 12.5% respectively]. The Most detectable chlorinated hydrocarbones residues were total DDT in Both Meat samples either beef or mutton, while Toxaphene residue could not be detected in beef Meat. All examined samples were sanitary safe for human consumption according to comparison with FAO/WHO records the chlorinated hydrocarbon residues gave us indicator for safety environment from different types of pollution
