Abstract
Abstract This study was undertaken to quantify the naturally occurring arsenic in the groundwater and chemical body burden caused by its ingestion at some villages of Fatehabad district, Haryana, India. The arsenic levels in groundwater were quantified by hydride generation atomic absorption spectrometry (HG-AAS). Arsenic concentration in the groundwater was found to be in the range of <0.05 to 4.53 μg L–1 which is within WHO and BIS acceptable limits (10 μg L–1). The significant positive correlation between pH - As (r=0.38**; P<0.01) showed that arsenic is more soluble in water at higher pH values. Oral arsenic exposure via groundwater ingestion ranged from <0.003 to 0.31 μg kg–1 day–1 which is significantly lower than WHO and BIS acceptable level (0.68 μg kg–1 day–1). The calculated non-cancer health risk was <1.0 which indicated that chemical burden caused by arsenic through drinking water in the study area is not a cause of concern. The calculated carcinogenic health risk was in the range of <5.06E-06 - 4.59E-04 which is slightly higher than acceptable limits.
