| Abstract: | The distribution of trace elements like Cu, Zn, Ni, Co and Mn in the waters of Pulicat lake has been studied in four aqueous environments — northern, central, southern and channel parts. It is observed that the concentration of the trace elements increase with increase of pH, chlorides and sodium in both monsoon and dry seasons. The concentration and the behaviour of the trace elements are controlled by adsorption, supplemented by organic reactions and by precipitation in sulphide-rich environments. |
