Effect of Nutrients on Bioaccumulation of Heavy Metals in a Tropical Urban Coastal Lacustrine System
The study on bioaccumulation of heavy metals in a lake reveals that during the nonrainy season, accumulation of cadmium in plankton is high in the upstream of the lake where anoxic freshwater condition exists resulting from inflow of urban wastes. Stern action is required to stop the bypass of sewage from the old sewer system especially in the commercial areas of Thiruvananthapuram city, either by augmenting the sewerage system or by treating sewage at the source. During monsoon season, the accumulation of heavy metals—namely lead and nickel, followed by cadmium and chromium—is high in phytoplankton resulting from high nitrate content caused by heavy rainfall. During postmonsoon, lead and nickel accumulation is high. The study emphasizes the need for stormwater management practices for the removal of lead in urban runoff from roads caused by vehicular exhaust, tire wear, and wastes from service stations and workshops.
