Monitoring of Organochlorine Pesticides Residues in Pumpkin(Cucurbita maxima), Brinjal(Solanum melongena),Cucumber {Cucumis sativus),Ridge Gourd(Luffa aegyptiaca) and Apple Gourd(Praecitrullus fistulosus)Vegetables by using QuEChERS Method

摘要

The continuous use of pesticides infected vegetables poses a leading threat to public health.Gas chromatography equipped with electron capture detector(ECD)was used to monitored 20 organochlorine pesticides including isomers of benzene hexachloride(α-BHC,β-BHC,γ-BHC,δ-BHC),heptachlor,aldrin,heptachlor epoxide,γ-chlordane,α-chlordane,endosulfan-I,4,4'-DDE,dieldrin,endrin,4,4'-DDD,endosulfan n,endrin aldehyde,4,4'-DDT,endosulfan sulfate,methoxychlor and endrin ketone were monitored in five summer vegetables(pumpkin,brinjal,cucumber,ridge gourd and apple gourd)by using Quick,Easy,Cheap,Effective,Rugged and Safe(QuEChERS)method.All vegetables were found contaminated with pesticides.Only apple gourd was found contaminated with one pesticide,rest of the vegetables was found contaminated with four or more than four pesticides..The concentrations of estimated pesticides were less than the maximum residue limit values but regular eating of pesticide contaminated vegetables may create serious health problems.The results of study indicated the need for strict guideline and regular monitoring of banned pesticide residues in vegetables to protect consumer's health.
