Abstract

During the past ten years (2000-2009), a continuous survey has been conducted to assess the concentration of trace metals in the water from three parts of Daye Lake. The results indicate that: 1) concentration of three trace metals exceed the Chinese drinking water standard measures; out of these As exceeded significantly by 70% followed by Pb and Cd which are 66.67% and 13.34% respectively; 2) all the water in Daye Lake had been polluted by trace metals and had high potential health risk as a drinking water resource for human beings; among the three research areas of Daye Lake: Sanli Qi Lake had the highest health risk (58.8 × 10−4), followed by Yinjia Lake (24.12 × 10−4), while Main Lake had the lowest health risks (3.84 × 10−4); 3) no significant correlations between these trace metals was observed (p < 0.5) which suggest they originated from diverse pollution sources.
