Abstract

In the present study, the environmental and occupational exposure of lead (Pb) has been assessed by analyzing the whole-blood samples of early adolescents (boys) aged 12–15 years working for the past 1–3 years in battery recycling workshops (BRW). For comparative purpose, boys of the same age group residing in the vicinity of BRW (exposed non-workers) and who lived in domestic areas devoid of any industrial activity (referents boys) were selected. The blood samples were analyzed for Pb, along with biochemical parameters of blood. Both biological samples were oxidized by acid in a microwave oven before determination of Pb by graphite furnace atomic absorption spectrometry. The mean value of Pb concentration in blood samples of working boys was threefold higher as compared with referent boys. The significant negative correlations of blood Pb level with % Hb (r=−0.862) were observed in working boys.
