Dietary Arsenic Exposure in Bangladesh

Abstract

When drinking water concentrations exceeded the Bangladesh drinking water standard of 50 microg As/L, ingested water was the dominant source of exposure. However, as drinking water As concentrations decrease, the relative contribution of dietary As sources becomes more important to ingested dose. The combined intake from both diet and drinking water can cause some individuals to exceed the PTDI in spite of using a tube well that contains < 50 microg As/L.
