چکیده
Rivers and Lake are most important water resource in India for purpose like drinking water supplies, irrigation and fisheries. The inland fresh water ecosystem, both lentic and lotic contributes a greater fraction towards the available water resource on the planet which, is now being increasingly subjected to greater stress from various human activities. Present investigation indicated that, Puliyanthangal and Maniyampattu Lake of Ranipettai, water samples were highly polluted and were not safe for drinking water purpose as the values for different parameters; especially toxic heavy metals evaluated high concentrations (Cu, Zn, Mg, Cr, Pb and Cd were 35.00, 19.99, 145.50, 0.143, 3.00 and 1.50 mgl respectively at both the stations for above the acceptable 1 limits. In addition to the phytoplankton, biomass, species composition and biodiversity are decreasing from month to month. Therefore, it is concluded from the present study, the Puliyanthangal and Maniyampattu Lakes of Ranipettai is rapidly getting polluted with these domestic and industrial sources thus substantiating the view of other workers, who reported that the Ranipettai areas are definitely the biodiversity of phytoplankton should be affected in those Lakes. So these results clearly, indicated that local hydrograph, monthly variability, physico-chemical and plankton biodiversity state are factor which cannot be neglected in studies of the occurrence of phytoplankton biodiversity in Lake waters.
