Time to Recognize and Address the Serious Arsenic Problem.

Abstract

Chronic low-level exposure to arsenic has a dose-dependent relationship with many chronic diseases. However, the typical arsenic safety standards used by governmental entities and laboratories appear inconsistent with current research. This editorial reviews the research and suggests that the random first-morning-urine total arsenic threshold for increased disease risk should be 5.0 μg/g creatinine or lower.
