Short report: Arsenic contamination in drinking water and skin manifestations in lowland Nepal: The first community-based survey

Abstract

A community-based, dose-response study on arsenic contamination was conducted in three communities in Terai in lowland Nepal. The arsenic concentration of all the tube wells in use (n = 146) and the prevalence of arsenic-induced skin manifestation among 1,343 (approximately 80% of the inhabitants) subjects indicated the existence of a highly contaminated area in Terai. It was found that overall prevalence of arsenicosis among the subjects a 15 years old was 6.9%, which was comparable to those found by the same examiner in arsenic-contaminated areas in Bangladesh, and that males had prevalence a twice as high as females, which could not be explained by the difference in the exposure level.
