Detection of some pesticides residues in raw milk

الملخص EN

Milk could be contaminated with pesticides from fodder, soil and ingestion of insecticides due to widespread application of pesticides in agriculture.

Therefore, the present study was conducted to determine the concentration of organochlorine (OC), synthetic pyrethroids and organophosphorus (OP) pesticide, using chromatography mass spectroscopy in milk samples collected from El-Beheria governorate, Egypt.

The obtained results revealed that OCPs Hexachlorocyclohexane isomers Alph, gama &Delta (HCHs), Heptachlorepoxide, Aldrin, ϒ- chlordane, Dieldrin, DDE, DDD and Methoxychlor and were monitored at percent of 3.3, 13.3, 83.3, 93.3, 3.3, 13.3, 23.3, 60, 70 and 83.3 % respectively, in the examined milk samples while Heptachlor, Endosulfan, Endrin and DDT were not detected in the same samples.

Synthetics pyrethroids including (cypermethrin, deltmethrin, Fenvaluate, Lambda_cyhalothrin and Permethrin) were detected at 60, 40, 50, 56.7 and 60 % of examined samples while, Fenopropathrin was not detected in the examined milk samples.

Concerning OP pesticides, all examined milk samples were contaminated with Diazinon 30 (100%), while Chlopyrifos was detected in only one sample 1 (3.3%), other OP pesticides were not detected in the examined samples.

This study investigated only pesticides residues and illustrated the risks of pesticides residues exposure that threaten consumer health.

Thus, monitoring survey of pesticide residues in milk is necessary to safeguard consumer health.
