The study was carried out to determine the concentration of heavy metal ions in and around this area. Four surface water samples were collected from in and around Beehar river, Rewa during summer, rainy and winter season during the year of 2015-17. 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.
