Residues of the organoichlorine pesticides nanich. (alpha + beta
hexachlorocychlohexane, lindane. aldrin, dicidrin, endrine and total DDT) and
the organophosphorus pesticides (pirimiphos-methvl 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 very low
amounts of alpha + bcta-HCH, lindane and DDT. below the acceptable limits of
the FAO. Aidrin. 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.
