Assessment of toxic effect of industrial effluent on aquatic life in the River Gagan at Moradabad-India

The industrial effluent generally contains heavy metals like Ni, Cr and Cu etc., which are discharge into sewers, drains, fields and into rivers. During present investigation, the toxicity of industrial effluent was investigated using fish “Labeo Rohita” and was found that fish was unable to survive in 10% concentration of the effluent. A very interesting feature of the study was that when the pH of the effluent decreased the toxicity of the effluent increased several times. It also found by the study that among three metals (Ni, Cr and Cu) Chromium is more toxic than other two metals
