摘要

Widespread groundwater contamination with arsenic in Bangladesh was recognized 15 years ago but over 40 million villagers remain exposed today. Over the same period, irrefutable evidence of the health impacts and economic costs of exposure has accumulated. A reinvigorated mitigation effort requires recognition at the national level of the need for(l)a permanent network of reliable arsenic testers responding to any household owning a well, and (2) the installation of many more low-arsenic public wells, with their siting more strongly linked to need and public access. Field experiments comparing different ways of meeting these objectives at scale are urgently needed. The reduction in rice yield caused by the accumulation in paddy soil of arsenic contained in irrigation water is an emerging issue. The benefit to farmers of mapping affected portions of their fields for soil removal using an arsenic kit could help sustain a network of well testers.
