Abstract

Due to widespread use of agrochemicals, such as organochlorines (OC), organophosphosphates (OP) and pyrethroids pesticides, consumers are exposed to insecticides via food daily. Upon the extraction of commonly consumed fruits and vegetables, researchers have demonstrated the prevalence of OC, OP and pyrethroid pesticides in these matrices. Despite advancements in pesticide residue analysis of food, there is still a need for the further indulgence of environmentalists for carrying and sorting proper multi-residue methods. Via these methods, researchers can investigate pesticidal dietary exposure of small populations by introducing innovative sample compositing techniques. Consequently, it was recognized that regularly consumed marketable fruits and vegetables contain measurable quantities of OC, OP and pyrethroid pesticides, adopted analytical methods for quantifying amounts of these pesticide residues in the mentioned food commodities, and applied methodologies to relative samples collected from 3 markets at 3 different localities. Having done so, this thesis aims to estimate the magnitude of exposure that the local population faces through some common marketable foods – fruits and vegetables in the present study.
