INTRODUCTION To understand the severity of related health effects of chronic arsenic exposure in West Bengal, a detailed 3-year study was carried out in Murshidabad, one of the nine arsenic-affected districts in West Bengal. METHODS We screened 25,274 people from 139 arsenic-affected villages in Murshidabad to identify patients suffering from chronic… (More)
In the recent past, arsenic contamination in groundwater has emerged as an epidemic in different Asian countries, such as Bangladesh, India, and China. Arsenic removal plants (ARP) are one possible option to provide arsenic-safe drinking water. This paper evaluates the efficiency of ARP projects in removing arsenic and iron from raw groundwater, on the… (More)
The incidence of high concentrations of arsenic in drinking-water has emerged as a major public-health problem. With newer-affected sites discovered during the last decade, a significant change has been observed in the global scenario of arsenic contamination, especially in Asian countries. This communication presents an overview of the current scenario of… (More)
Arsenic contamination of rice by irrigation with contaminated groundwater and secondarily increased soil arsenic compounds the arsenic burden of populations dependent on subsistence rice-diets. The arsenic concentration of cooked rice is known to increase with the arsenic concentration of the cooking water but the effects of cooking methods have not been… (More)
The effectiveness of arsenic removal plants (ARPs) to provide safe water was evaluated based on a study of 577 ARPs out of 1900 installed in 5 arsenic-affected districts of West Bengal, India. Out of 577, 145 (25.1%) were found in defunct condition. Both raw and filtered water from 305 ARPs were analyzed for total arsenic concentration. Forty-eight ARPs… (More)
In arsenic contaminated areas of the Ganga-Meghna-Brahmaputra (GMB) plain (area 569,749 sq. km; population over 500 million) where traditionally cow dung cake is used as a fuel in unventilated ovens for cooking purposes, people are simply exposed to 1859.2 ng arsenic per day through direct inhalation, of which 464.8 ng could be absorbed in respiratory tract.
In a recent publication, " Reliability of a commercial kit to test groundwater for arsenic in Bangladesh " (1) regarding the effectiveness of the Hach EZ arsenic kit (product 2822800), Van Geen et al. remarked " Clearly the Hach kit should continue to be used to test wells throughout Bangladesh and other countries affected by elevated arsenic in groundwater… (More)
Muhkkerjee et al. raise three main objections to our recent recommendation that a commercial field kit continue to be used to test well water for arsenic throughout Bangladesh (1, 2): (1) our study did not have broad enough coverage to constitute a representative evaluation of the kit; (2) many wells have been and will continue to be misclassified on the… (More)
