The pollution of the environment with toxic heavy metals is spreading throughout the world along with industrial progress. Cadmium, chromium, cobalt, copper, manganese, mercury, molybdenum, nickel and zinc are known to be the most commonly heavy metals used and the more widespread contaminants of the environment. Traces of these heavy metals are necessary as Co-factors of enzymatic reactions, but high levels of them may cause extreme toxicity to living organisms due to inhibition of metabolic reactions. In the present investigation, the sewage water collected from Bindal River Dehradun from different sites was investigated for heavy metal contamination.
