Abstract

Surface waters from 6 stations of riverine and coastal waters of Palar river, Mahabalipurm were collected. The hydrographic parameters for these samples were determined by conventional techniques. The DPASV technique was used for the determination of various forms of trace metals like Zn, Pb, Cu and Cd. The total dissolved metals were determined after UV-irradiation of the 0.45 μ filtered water samples. The ASV labile metals in the filtered water samples were determined at natural pH. The suspended particulate matter retained on the 0.45 μfilter paper were digested by using strong acids and the same were used for the determination of suspended particulate bound metals. The total dissolved metals were in general high at the riverine stations compared to coastal stations. However, last two stations on the seaside were showing higher values relative to the station close to the mixing zone. It was found that the percentages of ASV labile and non-labile forms varied widely with respect to the season at different stations. The particulate Zn, Pb and Cu were showing higher values in the monsoon season in riverine waters and in the summer/pre-monsoon for coastal waters. The higher values of the metals in the riverine side and last two stations on the seaside indicate trace metal pollution in the transect.
