摘要：

The concentrations of three heavy metals chromium (Cr), cadmium (Cd) and lead (Pb) were examined in water, sediment and green algae (Ulva lactuca); collected from six different stations at Pulicat Lake, which receives effluents from industries located in North Chennai Coastal region. Concentrations of Cd (64.21 mu g g(-1)) and Cr (28.51 mu g g(-1)) were found to be high in sediment, whereas in green algae concentration of Pb (8.32 mu g g(-1)) was higher than water and sediment samples. The relative abundance of these heavy metals in U. lactuca and sediment were found to be in the order Cd > Cr > Pb, whereas in water the ratio was found to be Cr > Pb > Cd. The seasonal variations in Cd and Pb followed a similar pattern in both seaweeds and sediments, but not in water samples. Spearman correlation coefficient study showed no significant correlation in the concentration of metals in U. lactuca, water and sediment samples. (c) 2007 Elsevier Ltd. All rights reserved.
