Does arsenic-contaminated drinking water limit early childhood development in Bangladesh?

Arsenic contamination in shallow groundwater aquifers remains a major barrier to providing access to safe drinking water in Bangladesh. Chronic exposure to arsenic has been shown to cause serious health impacts, including various cancers, skin lesions, neurological damage, heart disease, and hypertension. Numerous epidemiological studies have shown cognitive impacts on …

Drinking water sources in India: how safe is safe?

Under the loom of extreme climatic perturbations, human expansion and rising demand, world’s freshwater reserves are expected to suffer severe setbacks in the coming years. A major task for the international authorities in this regard is to develop a reliable inventory of existing potable water sources and identify the challenges …

National water quality sub-mission guidelines to provide safe drinking water in remaining arsenic and fluoride affected habitations in rural India on mission mode

About 76 percent of rural habitations in India have achieved a fully covered (FC) status, under the National Rural Drinking Water Program, with basic minimum service level of 40 liters per capita daily (lpcd), but this coverage is primarily through hand-pumps and does not necessarily translate into sustainable and good …

Developing sustainable models of arsenic-mitigation technologies in the Middle-Ganga Plain in India

This study seeks to understand factors that guide the decision-making process to adopt and implement the available arsenic-mitigation technologies in rural areas in the middle-Ganga Plain in India. A total of 340 households comprising 2500 people were surveyed. Socio-economic and demographic factors, water and sanitation status, time spent and distance …

Question raised in Lok Sabha on Arsenic and Fluoride in Ground Water, 06/04/2017

Question raised in Lok Sabha on Arsenic and Fluoride in Ground Water, 06/04/2017. Number of habitations and population affected by fluoride and arsenic contamination in ground drinking water sources in North East Region including Assam as reported by the States into Integrated Management Information System (IMIS) of the Ministry as …

Association of cardiometabolic genes with arsenic metabolism biomarkers in American Indian communities: The Strong Heart Family Study (SHFS)

Metabolism of inorganic arsenic (iAs) is subject to inter-individual variability, which is explained partly by genetic determinants. Researchers investigated the association of genetic variants with arsenic species and principal components of arsenic species in the Strong Heart Family Study (SHFS). Original Source

Question raised in Rajya Sabha on Clean drinking water for arsenic affected areas, 12/12/2016

Question raised in Rajya Sabha on Clean drinking water for arsenic affected areas, 12/12/2016. As per the Centrally sponsored National Rural Drinking Water Programme (NRDWP), administered by the Ministry of Drinking Water and Sanitation, every rural citizen should have access to a basic minimum service level of 40 (forty) litres …

National Sub-Mission guidelines to provide safe drinking water in remaining arsenic and fluoride affected habitations in rural India on mission mode

About 76 percent of rural habitations in India have achieved a fully covered (FC) status, under the National Rural Drinking Water Program, with 40 liters per capita daily (lpcd), but this coverage is primarily through hand-pumps and does not necessarily translate into sustainable and good quality service delivery.

Evaluation of inorganic fractions of arsenic in relation to soil properties in affected areas of West Bengal, India

Inorganic soil arsenic (As) in three soils was fractionated adopting phosphorus fractionation schemes. Among these fractions, iron-bound arsenic (Fe-As) was found highest, followed by aluminium-bound arsenic (Al-As). The freely exchangeable arsenic was relatively small compared to the arsenic held by internal surfaces of soil aggregates. The arsenic fractions exhibited positive …

Poultry consumption and arsenic exposure in the U.S. population

Arsenicals (roxarsone and nitarsone) used in poultry production likely increase inorganic arsenic (iAs), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), and roxarsone or nitarsone concentrations in poultry meat. The association between poultry intake and exposure to these arsenic species, as reflected in elevated urinary arsenic concentrations, however, is unknown. Original Source

Megacity pumping and preferential flow threaten groundwater quality

Many of the world’s megacities depend on groundwater from geologically complex aquifers that are over-exploited and threatened by contamination. Here, using the example of Dhaka, Bangladesh, we illustrate how interactions between aquifer heterogeneity and groundwater exploitation jeopardize groundwater resources regionally. Groundwater pumping in Dhaka has caused large-scale drawdown that extends …

More than half of south Asia's groundwater too contaminated to use – study

Salinity and arsenic affect 60% of underground supply across vast Indo-Gangetic Basin, according to research published in Nature Geoscience Fifteen to twenty million wells extract water from the Indo-Gangetic basin every year amid growing concerns about depletion. Sixty per cent of the groundwater in a river basin supporting more than …

Groundwater quality and depletion in the Indo-Gangetic Basin mapped from in situ observations

Groundwater abstraction from the transboundary Indo-Gangetic Basin comprises 25% of global groundwater withdrawals, sustaining agricultural productivity in Pakistan, India, Nepal and Bangladesh. Recent interpretations of satellite gravity data indicate that current abstraction is unsustainable, yet these large-scale interpretations lack the spatio-temporal resolution required to govern groundwater effectively. Here we report …

Urban water pumping raises arsenic risk in Southeast Asia

Large-scale groundwater pumping is opening doors for dangerously high levels of arsenic to enter some of Southeast Asia's aquifers, with water now seeping in through riverbeds with arsenic concentrations more than 100 times the limits of safety, according to a new study from scientists at Columbia University's Lamont-Doherty Earth Observatory, …

Official denies claim that Pearl Delta water is arsenic-ridden

Environmental authorities in South China's Guangdong Province have questioned a Canadian scholar's claim that arsenic levels in groundwater in some parts of the Pearl River Delta are 15 times higher than the international standard, while experts affirmed the situation is severe. John Cherry, a Canadian hydro-geologist, told Hong Kong-based Oriental …
