摘要：With regard to the point that studies should assess arsenic concentrations 150–500 μg/L in drinking water, there is good evidence that arsenic in water may increase the incidence of diabetes. However, every study that has produced strong evidence has included water arsenic concentrations > 500 μg/L at, or before, the time of the study. Indeed, Maull et al. (2012) cited one large, well-designed study in Bangladesh (Chen et al. 2010) with water arsenic con-centrations up to 500 μg/L that found no evidence of increased diabetes, even among the > 2,000 participants with urinary arsenic concentrations > 200 μg/L
