摘要：Four water samples were collected following accepted procedures from each of the three lakes Agara,Hebbal and Madiwala at different locations during the dry season month of February 2009 and rainy seasonmonth of July 2008. The levels of heavy and toxic metals As, Cu, Fe, Hg, Mn, Ni, Pb, Sb and Zn weredetermined using ICP-AES in sequential mode, and were found to be within the desirable and permissiblelimits. But the water samples of Hebbal and Agara lakes were found to be containing lead that was exceedingthe desirable limit prescribed by WHO and Central Pollution Control Board and was more in the dry seasonsamples than those in the rainy season. These two lakes are surrounded by motor ways leading to variousparts of the country including the Ring road and National Highway-7, where there are heavy vehicularmovements and are obvious major contributors in addition to those from multiplicities of urban developments.
