Water pollution study of the Shirvane and Nerul lakes situated at Nerul, Navi Mumbai, India

0
The areas of study selected in the present investigation are Shirvane and Nerul lakes situated at Nerul which is considered as the queen of Navi Mumbai, the city on the west coast of the Indian state of Maharashtra. The lake areas receive domestic raw sewage from surrounding habitation; so also the activities like cattle and cloth washing, bathing, religious activities like idol immersion etc. paves the way of harmful chemicals in the lake water. The study was performed to understand physico-chemical parameters and the concentration of heavy metals in lake water. It was found that the concentration of the heavy metals in the lake water substantially increased after the religious activities like idol immersion around September-October. These heavy metals have a marked effect on the aquatic flora and fauna which through bio-magnification enter the food chain and ultimately affect the human beings as well.
