Blood Lead Level (BLL) in the Adult Population of Jodhpur: A Pilot Study

Lead interferes with a variety of body processes and is toxic to many organs and tissues including the heart, bones, intestines, kidneys, and reproductive and nervous systems. Routes of exposure to lead include contaminated air, water, soil, food, and consumer products. The possibility of lead exposure in humans is therefore of great significance from health point of view. Occupational exposure is a common known cause of lead poisoning in adults but current status of adults exposed otherwise is not known. School teachers representing wide local population were selected and asked to furnish information regarding possible lead exposure. Blood lead level (BLL) was estimated using anodic stripping voltammetry. The mean BLL was 6.89 ± 9.5 μg/dl ( 65 μg/dl) in representative adult population. Out of the total 16 % were found to be having BLL >10 μg/dl which has significantly decreased from leaded gasoline era. Those with increased BLL (>10 μg/dl) were found to have common determinants like usage of old metallic pipes for plumbing, water consumption without any purification system, usage of cosmetics and Ayurvedic/herbal medicines.
