Bio-monitering of automobile workers for lead contamination

Abstract

Widespread use of metals in industrial activities has enhanced the occupational exposure to toxic metals as well as the health risk of metal hazards to human. Elemental analysis in the human tissues is the most common application of biological monitoring of screening, diagnosis and assessment of such exposure and risk. Among various biopsy materials, Blood, nails, hair, teeth and body fluids may be used as bio indicators for this purpose. The present paper includes the quantitative determination(by atomic absorption spectrophotometer/AAS)for lead metal concentration in blood samples of persons who are working in garages and automobile workshops and this increased level of lead in humans cause so many health problems like kidney disorder or failure, anaemia and some times hypertension, water borne diseases.
