Physico-Chemical and Microbiological Profile of Effluents from Common Effluent Treatment Plants (CETPs)

Due to rapid industrial progress and urbanization, environmental pollution with toxic heavy metals has become one of the major concerns in today’s world (Kinare and Shingadia 2014). Environmental pollution due to chemicals and heavy metals is spreading throughout the world and is a problem that may have negative consequences on the hydrosphere. Metal contaminated aquifers pose serious threat to health and ecosystems. Copper, chromium, cadmium and nickel are known to be the most commonly used heavy metals and are the more widespread contaminants of the environment (Aksu 1998, Doenmez and Aksu 1999). Some heavy metals are essential in trace amount, but high levels of them may cause extreme toxicity to living organisms due to inhibition of metabolic reactions. These are considered to be more persistent and stable than organic International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 6 Number 9 (2017) pp. 1403-1413 Journal homepage: http://www.ijcmas.com
