Abstract

Organisms inhabiting in water require little amount of trace elements. At finest level they are favorable and further than that edge it affected fatal to the ecosystem. Continuous dumping of impurities like heavy metals from various supplies in significant quantities are constantly discharged into the rivers reaches estuaries and oceans. For the reason of this unwanted human liberation oceanic biosphere is recognized to hold heaviness of heavy metals. For most of the heavy metals estuarine sediments form the ultimate catch. The metals entering the system through various sources may associate with the sediment particles either by absorption are gradually sink with sediment or they may get released when mixed with marine water due to altered physico-chemical environment. Veli Lake is polluted by different means which is situated in the south west coast of India (Kerala). The additional quantities of heavy metals come from agricultural, industrial and domestic wastes. Hence sediments are indicators of the quality of overlying water, for the present study five different heavy metals were analyzed from the sediments of Veli Lake. Monthly collection of sediments and analysis were carried out for a period of one year (April-2017 to March-2018). The five metals analyzed were copper, lead, manganese, nickel and zinc. Low levels of copper were observed in all the stations while comparing other metals. The seasonal variations were also noted for all the five metals and discussed.
