Risk assessment due to intake of heavy metals through the ingestion of groundwater around two proposed uranium mining areas in Jharkhand, India

Abstract

Heavy metal pollution of water resources can be apprehended in East Singhbhum region which is a highly mineralised zone with extensive mining of copper, uranium and other minerals. Ten groundwater samples were collected from each site and the heavy metal analysis was done by atomic absorption spectrophotometer. Analysis of the results of the study reveals that the concentration of iron, manganese, zinc, lead, copper and nickel in groundwater of Bagjata mining area ranged 0.06-5.3 mg l(-1), 0.01-1.3 mg l(-1), 0.02-8.2 mg l(-1), 1.4-28.4 μg l(-1), 0.78-20.0 μg l(-1) and 1.05-20.1 μg l(-1), respectively. In case of Banduhurang mining area, the range was 0.04-2.93 mg l(-1), 0.02-1.1 mg l(-1), 0.01-4.68 mg l(-1), 1.04-33.21 μg l(-1), 1.24-18.7 μg l(-1) and 1.06-14.58 μg l(-1), respectively. The heavy metals were found to be below the drinking water standards (IS:10500 1993) except iron (0.3 mg l(-1)) and manganese (0.1 mg l(-1)). The hazard quotients of the heavy metals for drinking water were below 1 posing no threat due to intake of water to the people for both the areas.

Risk Assessment of Radionuclides and Heavy Metals in Ground Water in Selected Water Wells in Northwestern of Egypt.

“…These results were in agreement with (Giri et al, 2012) studied the hazard quotient (HQ) for risk assessment due to intake of heavy metals through the ingestion of groundwater on ten groundwater samples collected from each sit Bagjata and Banduhurang area, India taking into account average water consumption of 1.48 m3 year −1 by an Indian adult. The HQs of all the considered heavy metals were below the threshold value of 1 as suggested by (USEPA, 1993).…”

Human health risk assessment via drinking water pathway due to metal contamination in the groundwater of Subarnarekha River Basin, India

“…There is a growing concern over the metal pollution of the environmental components of Subarnarekha River Basin. The intense industrialization of the basin has also been a major contributor of certain metals to the water and sediment of the river basin (Upadhyay et al 2006;Giri et al 2012Giri et al , 2013Giri and Singh 2014). The studies also indicate that the metal pollution is more pronounced in the pre-monsoon season.…”

Evaluation of groundwater quality in the Chotanagpur plateau region of the Subarnarekha river basin, Jharkhand State, India

“…Giri et al (2010) have assessed the concentration of heavy metals (Fe, Mn, Zn, Pb, Cu, and Ni) in the groundwater of East Singhbhum region and found that Fe and Mn concentrations were higher than permissible limit. Health risks due to intake of heavy metals through the ingestion of groundwater around uranium mining areas in Jharkhand were also reported by Giri et al (2012).…”
