Assessment and seasonal variations of heavy metal contamination of surface water in Murna river, Shahdol, Madhya Pradesh
The present work is assessment the seasonal variation in metal pollution and the ecological risk indices of surface water of the Murna River, Shahdol during summer, rainy and winter season during the year of 2019-20. The concentration of trace metals such as arsenic, chromium, cadmium, copper, iron, manganese and zinc were determined using atomic absorption spectrophotometer and the results were compared with the World Health Organization (WHO) and Bureau Indian standard (BIS) values. They are extremely dangerous for the health of fish. Most of these metals are characterized by being accumulated in tissues, and lead to the poisoning of fish. These metals can effectively influence the vital operations and reproduction of fish; weaken the immune system, and induce pathological changes. As such, fish are used as bio-indictors, playing an important role in monitoring heavy metals pollution. It is very important to assess and monitor the concentrations of potentially toxic heavy metals and metalloids in different environmental segments and in the resident biota.
