Abstract
Average concentration of Pb in air particulates in different suburbs of Mumbai during 1998-2001 varied between 0.11 and 0.35 $\mu$ g m ^-3. The concentration of Pb in all the residential suburban atmosphere is well below the Central Pollution Control Board (CPCB, 1994) prescribed limit of 1 $\mu$ g m ^-3. The daily intake Pb for Mumbai children through ingestion was found to vary from 13.9-18.9 $\mu$ g. The concentrations of Pb in blood of 6-lOy old children residing in different suburbs of Mumbai were found to vary from 8.3 to 9.8 $\mu$ g dl ^-l. The correlation between blood lead of children and air lead reveals that the blood Pb level in children could increase by 3.52 $\mu$ g dl ^-1 for an incremental rise of 1.0 $\mu$ g m ^-3 of air Pb concentration.
