Residues of the organolchlorine pesticides namely. (alpha + beta hexaehlorocychlohexane. lindane. aldrin, dieldrin, endrine and total DDT) and the organophosphorus pesticides (pirimiphos-methyl and malathion) were determined in home-produced tomatoes and cucumbers used for consumption in two Egyptian Governorates.
The analysed samples were collected randomely and periodically during March 1994 - April 1995 from the markets in Kalyubia and Cairo Governorates.
Results showed that most of the tested samples contained VCR' low amounts of alpha + beta-HCH, lindane and DDT, below the acceptable limits of the FAO. Aldrin. dieldrin and endrin residues were found frequently in a few number of the investigated samples. below the acceptable limits. Residues of alpha and beta HCH were found to be higher than the acceptable limit in. only. two samples of cucumbers. The organophosphorus insecticides pirimiphos-methyl and malathion were detected in most of the tomato and cucumber samples at very low levels below the allowed maximum residue limits. |
