Assessment of contamination of soil due to heavy metals around coal fired thermal power plants at Singrauli region of India
(2010) Prashant Agrawal; Anugya Mittal; Rajiv Prakash; Manoj Kumar; T.B. Singh; S.K. Tripathi
In the present study, an attempt was made to measure contamination of soil around four large coal-based Thermal Power Plants. The concentration of Cadmium, Lead, Arsenic and Nickel was estimated in all four directions from Thermal Power Plants. The soil in the study area was found to be contaminated to varying degrees from coal combustion byproducts. The soil drawn from various selected sites in each direction was largely contaminated by metals, predominantly higher within 2-4 km distance from Thermal Power Plant. Within 2-4 km, the mean maximum concentration of Cadmium, Lead, Arsenic and Nickel was 0.69, 13.69, 17.76, and 3.51 mg/kg, respectively. It was also observed that concentration was maximum in the prevalent wind direction. The concentration of Cadmium, Lead, Arsenic and Nickel was highest 0.69, 13.23, 17.29 and 3.56 mg/kg, respectively in west direction where wind was prevalent. © 2010 Springer Science+Business Media, LLC.
Contamination of drinking water due to coal-based thermal power plants in India
(Bellwether Publishing, Ltd., 2011) Prashant Agrawal; Anugya Mittal; Rajiv Prakash; Manoj Kumar; S.K. Tripathi
This study assessed the impact of an Anpara and Renusgar coal-based thermal power plants on drinking water sources. In this work, the concentration of trace metals such as Pb, Cd, Ni, and As in groundwater samples obtained from hand pumps located near these power plants were measured. The concentration levels of all the studied heavy metals in groundwater were found to be higher than the maximum acceptable limits of World Health Organization for drinking water. © Taylor & Francis Group, LLC.
