DETERMINATION OF ORGANOCHLORINE PESTICIDES (OCPs) RESIDUES IN VEGESTABLE AND SOIL SAMPLES AT OLD STORE IN HUNG YEN

Abstract

Organochlorinated pesticides (OCPs) residues in vegestable and soil surrounding stock or storage
areas has been a public concern. In this study, contents of 8 OCPs (including: endrin; dieldrin; o,p’-
DDE; p,p’-DDE; o,p’-DDD; p,p’-DDD; o,p’-DDT; p,p’-DDT) in 05 vegestable and 03 soil samples
collected from a store at Chinh Nghia, Kim Dong, Hung Yen were determined. While OCPs were not
detected in all vegetable samples and one soil sample (taken from a farmer's house about 500 meters
away from the store), most of the OCPs were detected in the other two soil samples (taken in front of
the door and behind the store) with content in the range of 17-891 ng/g dry weight. The obtained
results show that the need to pay attention to pesticide residues in old store in Hung Yen in particular
and in Vietnam in general.
