Pesticides and trace metals residue in grape and home made wine in Jordan

Sixty home made wine and sixty-four grape samples were collected from five territories in Jordan, where grapes and wine are mostly producted. The coll ected samples were analyzed for the most used organochlorine pesticides (OC P) and organophosphorous pesticides (OPP) in Jordan, as well as for four he avy metals (Ni, Cu, Zn and Pb). The results showed that OCPs residues were detected in 73% of the wine samples but no OPPs residue were detected which is due to generally shorter half life of the later pesticide. Grapes showe d higher incident of contamination than wine, however, OCPs and OPPs with b oth short and long half-lives were detected. The OPPs were detected in only 8.3% of the analyzed grape samples. Heavy metals showed higher values in g rapes than in the wine samples and it was attributed to removal of solids d uring wine preparation processes or through contamination of wine during st orage. Most of the samples were below toxic limit.
