Bio-monitering of automobile workers for lead contamination

Abstract

Occupational exposure to hazardous metals and the health risk of metal hazards to humans have both
increased as metal usage has become more widespread in industrial operations. Elemental analysis in the
human tissues is the most widespread application of biological monitoring of screening, diagnosis and
evaluation of such exposure and risk. Bioindicators may be extracted from a wide variety of biopsy
samples, including blood, nails, hair, teeth, and bodily fluids. This paper presents the results of a
quantitative determination (using atomic absorption spectrophotometer/AAS) of lead metal
concentration in the blood samples of people who work in garages and automobile workshops. High blood
lead levels are linked to a variety of health issues, including kidney disorder or failure, anemia, and
occasionally hypertension and water-borne diseases.
