RESUMO
Persons from fourteen different fruit and vegetable farms stations were examined for the presence of pesticide residues in their blood samples. The effect of residues on total bilirubin was studied. A significant difference between total bilirubin at different timings and at different stations was noted. Almost all the persons from different stations showed elevated levels of bilirubin. The exposure to different pesticides for prolonged period of time has affected the normal functioning of different organ systems such as liver, kidney and lungs and thus produced possible characteristic clinical effects
RESUMO
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
