Abstract
Atmospheric deposition of trace metals like Pb, Cd, Cu and Zn has been studied at Deonar, Bombay during 1988 and 1989. The atmospheric concentrations of these metals at Deonar as well as the levels of total suspended particulate matter (TSPM) at different locations in Bombay were also measured. The bulk deposition flux for these metals was found to vary from 0.3 to 102.1 kg km−2yr–1 while the dry deposition flux varied from 0.2 to 104.6 kg km−2 yr−1. Deposition velocities for these metals have also been estimated which varied from 0.05 to 2.5 cm s−1. The TSPM levels ranged from 17 to 588 μg m−3. The levels of TSPM were found to be at a minimum at Deonar and, as such, this study is believed to indicate representative minimum deposition values for Bombay.
1988年和1989年在印度孟买的Deonar研究了微量金属Pb、Cd、Cu和Zn的大气沉降。还测量了Deonar的这些金属的大气浓度以及孟买不同地点的总悬浮颗粒物(TSPM)水平。这些金属的大块沉积通量在0.3至102.1 kg km - 2yr-1之间变化，而干沉积通量在0.2至104.6 kg km - 2yr-1之间变化。对这些金属的沉积速度也进行了估计，其变化范围为0.05 ~ 2.5 cm s−1。TSPM水平为17 ~ 588 μg m−3。在Deonar发现TSPM水平处于最低水平，因此，这项研究被认为是孟买具有代表性的最低沉积值。
