Do ponds cause arsenic-pollution of groundwater in the Bengal basin? An answer from West Bengal.
We report time-series data collected over two years for delta18O, delta2H, and Ca, Mg, K, and Cl, concentrations for 10 ponds in, and upflow of, an As-polluted region of southern West Bengal. We compare the compositions of As-polluted groundwaters from wells with the compositions of waters in ponds upflow, and within the range of influence, of the wells. Conservative tracers (delta18O, delta2H,...
متن کاملRegional hydrostratigraphy and groundwater flow modeling in the arsenic-affected areas of the western Bengal basin, West Bengal, India
The first documented interpretation of the regional-scale hydrostratigraphy and groundwater flow is presented for a ∼21,000-km area of the arsenic-affected districts of West Bengal [Murshidabad, Nadia, North 24 Parganas and South 24 Parganas (including Calcutta)], India. A hydrostratigraphic model demonstrates the presence of a continuous, semi-confined sand aquifer underlain by a thick clay aq...
متن کاملCreatinine, Diet, Micronutrients, and Arsenic Methylation in West Bengal, India
BACKGROUND Ingested inorganic arsenic (InAs) is methylated to monomethylated (MMA) and dimethylated metabolites (DMA). Methylation may have an important role in arsenic toxicity, because the monomethylated trivalent metabolite [MMA(III)] is highly toxic. OBJECTIVES We assessed the relationship of creatinine and nutrition--using dietary intake and blood concentrations of micronutrients--with a...
متن کاملGroundwater arsenic contamination in Bangladesh and West Bengal, India.
Nine districts in West Bengal, India, and 42 districts in Bangladesh have arsenic levels in groundwater above the World Health Organization maximum permissible limit of 50 microg/L. The area and population of the 42 districts in Bangladesh and the 9 districts in West Bengal are 92,106 km(2) and 79.9 million and 38,865 km(2) and 42.7 million, respectively. In our preliminary study, we have ident...
