The As concentration in the groundwater of Bangladesh reaches up to 4600 μg/L. Biotitic chemical weathering and the existence of other core minerals in aquifers are the primary sources of As in the groundwater of Bangladesh. Se hela listan på Se hela listan på The Bangladeshi government limits arsenic concentration in water to 50 μg/L, which is 5 times more than the WHO recommended limit. The government and other agencies like UNICEF installed wells to provide fresh water in underdeveloped areas of Bangladesh, but later found disease related to consumption of this water. 2020-05-07 · Neumann, R.

The arsenic concentration of rice produced in arsenic-contaminated area is 2 to 3 times higher than that produced in unaffected districts. The values of arsenic content of rice produced in Bangladesh and Japan The WHO recommended limit of arsenic concentration in ground water is 10 µg/L while Bangladesh permissible limit for arsenic is 50 µg/L. However, several tube-wells in Bangladesh have been found to contain arsenic in concentration that is beyond the permissible limit. Up to 75 million people in Bangladesh are at risk of arsenic exposure. Issue Globally and in Bangladesh •Countries where arsenic in drinking water has been detected at concentration >10 µg/L or the prevailing national standard – Argentina, Australia, Bangladesh, Chile, China, Hungary, India, Mexico, Peru, Thailand, and the United States of America •British Geological Survey study of wells in Bangladesh arsenic concentrations are typically found where sands outcrop at or near the surface; higher arsenic levels are observed underneath thicker fine-grained deposits. Optical luminescence, 210Pb, and 137Cs measurements indicate that the distribution of these deposits is not random and reflects local river history and floodplain development.

This study of 30 analytes per sample and 112 samples suggests that the most significant health risk from drinking Bangladesh's tubewell water is chronic As poisoning. The As concentration ranged from < 0.0007 to 0.64 mg/L, with 48% of samples above the 0.01 mg/L World Health Organization drinking water guideline.

Final Report - Organisation for the Prohibition of Chemical

In Bangladesh over 50 million people are exposed to naturally occurring arsenic concentrations exceeding the World Health Organization’s guideline of 10 μg/L. Selenium and arsenic have been shown to facilitate the excretion of each other in bile. Because of the regional geology, this biologically uncontaminated water is laced with naturally occurring arsenic in concentrations up to 40 times over the declared safe level. Arsenic as a public health problem was first identified in West Bengal, India, where the geological formations, economic conditions, food habits, and tube wells are similar to those in Bangladesh. Arsenic levels in rice can be further elevated in rice growing on arsenic contaminated soils, potentially greatly increasing arsenic exposure of the Bangladesh population.
