Study suggests large investment in Bangladesh water supply infrastructure would be justified

Two of Columbia's SRP Community Engagement Core scientists Sara Flanagan and Yan Zheng along with their colleague Richard Johnston published a paper in the November 2012 WHO Bulletin examining the health and economic impacts and implications for the mitigation of arsenic in tube well water in Bangladesh. A recent survey in Bangladesh estimates that 35 to 77 million people have been chronically exposed to arsenic in their drinking water. The health implications of chronic arsenic exposure in such a large population are substantial. Interventions in areas with the highest proportion of unsafe wells are likely to reach the population exposed to the highest arsenic concentrations and therefore at highest risk of experiencing adverse health outcomes. This paper provides evidence that large investments in the water supply infrastructure to reduce levels of arsenic in drinking water is economically justified when the health and economic burdens of unabated arsenic exposure are considered.

Water conservation case study and policy report

A new Rockland County water conservation case study and policy report was released August 17 by the Center for Regional Research, Education and Outreach at SUNY New Paltz. This discussion brief updates earlier work by the authors, Stuart Braman of Lamont-Doherty and Simon Gruber of the CUNY Institute for Sustainable Cities, and places it in the context of the Hudson River valley.

Variants Associated with Arsenic Metabolism and Toxicity Phenotypes in Bangladesh

A research team led by CU SRP PI Habibul Ahsan and Brandon Pierce, University of Chicago Medicine, with contributions by SRP scientists Marie Argos, Joseph Graziano, Mary Gamble, Faruque Parvez, and Vesna Slavkovich has discovered genetic variants that elevate the risk for skin lesions in people chronically exposed to arsenic, as part of the first large-scale genomic studies in a developing country. Genetic changes found near the enzyme for metabolizing the chemical into a less toxic form can significantly increase an individual's risk for developing arsenic-related disease (summary link below).

Manganese Exposure from Drinking Water and Children’s Classroom Behavior in Bangladesh

As part of the SRP child development project in Araihazar, Bangladesh, this cross-sectional study investigates the associations of manganese and arsenic in tube well water with classroom behavior among more than 200 elementary school children, 8–11 years of age.  The study examines specificity in the exposure/behavior problems by assessing both exter­nalizing and internalizing behavior. Its findings reinforce the growing concern regarding neurotoxicologic effects for children exposed to high manganese levels in drinking water.
