Pesticide residues in random blood samples of human population in Karachi

ABSTRACT

Thirty random samples of blood were taken for pesticide determination from three different laboratories in Karachi. Almost all the samples reported here were found contaminated with organochlorine [OC] compounds. However, samples obtained from 2 centres were found to have more pesticides. Workers deputed to chlorination plants [i.e. third centre] have greater quantity of tenakil and other OC compounds. Among all the samples analysed, only a few were found to have deltamethrin [pyrethroid] and malathion [organophosphate] possibly because of fresh exposure
