摘要

Groundwater arsenic contamination in the middle Indo-Gangetic plains poses an emerging threat to livestock health. We determine the arsenic concentration in water and its bioaccumulation levels in feed and cattle reared in areas with arsenic groundwater contamination. Based on a preliminary survey and observations, ten cattle each from Akbapur village in the Naubatpur block as the control and from Kasimchak village in the Danapur block as the test group, were selected. All selections adhered to established inclusion criteria. Samples of feed, water, and other biological materials were collected from each group. The mean arsenic (mg/L) in water (0.0785 ± 0.004) and feed (1.046 ± 0.076) from test village were above the permissible levels and significantly higher than the control village. The arsenic concentrations in blood, milk, hair, urine, and dung were also significantly higher in test group compared to the control cattle. This study indicates that exposed cattle bio-accumulates arsenic.
