| Abstract: | Atmospheric concentrations of Pb, Cd, Cu and Zn have been measured at different locations in Bombay. The concentration levels of these metals in blood and teeth of Bombay residents were also measured to assess the current and integrated exposure. Higher atmospheric concentrations were observed in higher vehicular traffic zones in Bombay. Environmental monitoring of Pb, Cd, Cu and Zn was also carried out at Moradabad, the largest production and exporting centre of brass wares in India. Surface soil concentrations of these metals were also measured in Moradabad and Bombay. The analysis of samples was carried out by differential pulse anodic stripping voltammetry (DPASV). The study indicates that automobile exhaust is the dominant source for heavy metals in the environment of Bombay whereas the brass industry is responsible for enhanced concentrations of these metals in Moradabad. |
