The Atomic Absorption Spectrometer (AAS) was used in this work to assess the As content in groundwater samples from 38 shallow (27 m) tubewells in northwest Bangladesh to determine the existing situation, potential …

However, in most of the large-scale cases of geogenic arsenic contamination in groundwater, arsenic accumulates in aquifers composed of recently deposited alluvial sediments. Under anoxic …

Impact of Arsenic Contaminated Irrigation Water in Food Chain: An Overview From Bangladesh. Arsenic in ground water is a very serious environmental hazard of Bangladesh and West Bengal of India. The presence of high level of Arsenic (<50 µg/L) in groundwater of Bangladesh has been detected….

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. Today, despite a much-improved …

In Bangladesh, arsenic contamination in groundwater was first detected in the year 1993. According to the data provided by UNICEF in 2008, there are approximately 8.6 million tube-wells in Bangladesh. Of these, 4.75 million tube wells (55%) have been tested for arsenic among which 3.3 million ...

In the context of groundwater arsenic in Bangladesh, we challenge this notion here by showing that organic carbon drawn from a clay layer into a low-arsenic …

Arsenic is not just a Bangladesh problem — it can be found in drinking water supplies around the world. Maine, Massachusetts, Texas, and half a dozen other states have all had arsenic contamination problems, says Joseph Graziano, a professor of environmental health sciences and pharmacology at Columbia University.

Arsenic contamination in groundwater is a severe problem in Bangladesh to ensure a source of safe drinking water for the last three decades (Abedin & Shaw, 2013; Adeloju et al., 2021). The annual ...

More than 29 million people are affected by arsenic contamination, and 35-77 million are at risk of exposure in Bangladesh (Rahman, 2002). Due to arsenic related cancers (in liver, bladder, and ...

In Bangladesh, ground water arsenic (As) contamination has become a major public health problem. Millions of people are drinking As-contaminated water and this mass poisoning is the biggest As disaster in the world [ 5, 6, 7 ].

To date, we have collected 10,991 water samples from 42 arsenic-affected districts in Bangladesh for analysis, 58,166 water samples from nine arsenic-affected districts in West Bengal. Of the water samples that we analyzed, 59 and 34%, respectively, contained arsenic levels above 50 microg/L. Thousands of hair, nail, and urine samples from ...

Arsenic (As) contamination in groundwater has been disclosed in over 70 countries with a population of about 150 million people worldwide, with high concentrations discovered in ten countries in south and southeast Asia, namely Bangladesh, India, Cambodia, China, Laos, Myanmar, Nepal, Pakistan, Taiwan, and Vietnam, with over 110 …

Widespread use of arsenic-contaminated water in Bangladesh during the 20 th century has been called by the World Health Organization the largest mass poisoning in history. A new study co-authored by Yale economist Mark Rosenzweig finds that, in …

The contamination of groundwater by arsenic in Bangladesh is the largest poisoning of a population in history, with millions of people exposed. This paper …

Almost 57 million people in Bangladesh are at risk of arsenic-induced disease due to chronic contamination of their drinking water with arsenic concentrations exceeding the WHO limit . Contamination of shallow tube wells has resulted in 80% of the Bangladeshi population being exposed to arsenic as the groundwater was used for their …

The magnitude of groundwater As contamination in Bangladesh surfaced only after the International Conference on As held in Dhaka, Bangladesh (International Conference on Arsenic, 1998). During this conference, SOES and DCH reported that 66% and 51% of 8065 hand tubewells water samples from 60 districts of Bangladesh …

Although the government of Bangladesh has made its population's access to safe drinking water a priority agenda item, there are still pockets of the population that …

Arsenic (As) is a recognized naturally hazardous metalloid that has long been linked to human poisoning. Bangladesh is now dealing with a major public health crisis, with arsenic contamination in drinking water and food crops putting millions of people at risk.
