2021-02-02 · Similarly, this arsenic poisoning also caused lower schooling attainment, especially among younger Bangladeshi men who would have been exposed to the arsenic at early ages in contrast to older cohorts. Bangladeshis also saw the impact that arsenic poisoning had on their job prospects.

Background. Arsenic can naturally occur in the groundwater without an anthropogenic source of contamination. 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.

(2013) Redox-cycling of arsenic along water pathways in a sulfidic meta Twenty years ago, Smith and colleagues described groundwater arsenic (As) contamination in Bangladesh as the " largest mass poisoning of a population in history." An estimated 60 million people were unknowingly drinking groundwater containing dangerous concentrations of naturally occurring As. 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. Bangladesh has recognized the acceptable limit of arsenic concentration in water at 0.05 milligram/liter. Many people are suffering from arsenicosis and many more are at risk.

Arsenic concentrations in samples of water (n = 11), soil (n = 18), and rice-grain (n = 10). The maximum permissible limit of arsenic in drinking water in Bangladesh is 0.05 mg/l. The average arsenic concentration naturally occurring in the soil worldwide is 10 mg/kg.

Arsenic and the Nature of Groundwater Groundwater is a complex matrix in which many chemical species are present. Table 1 shows the compositions of typical groundwater found in Bangladesh.

The current paradigm within Bangladesh and West Bengal is that Fe(III) (hydr)oxides remain the dominant host of arsenic even at well depth (i.e., 30 to 50 m) within contaminated aquifers, and that organic carbon derived either from the surface or from detrital material (2, 3, 6) is stimulating reductive dissolution of the iron phases and concomitant release of arsenic.
