Estimation of Urinary Lead and Urinary δ-Aminolevulinic Acid as an Index of Lead Exposure in Urban and Rural Residents of West Bengal, India

Pb exposure was higher in urban than rural residents; furthermore, urban commercial residents had Pb exposure higher than urban residential residents. Results are evident that vehicular emissions and tobacco smoke were potential contributors to environmental Pb exposure among study participants. The present work provides data on Pb body burden among the residents of West Bengal that might be useful for policymakers and in pollution abatement strategies too.
