CHICAGO - A new analysis of government data is the first to link low-level arsenic exposure, possibly from drinking water, with Type 2 diabetes, researchers say. The study's limitations make more research necessary. And public water systems were on their way to meeting tougher U.S. arsenic standards as the data were collected.
Still, the analysis of 788 adults' medical tests found a nearly fourfold increase in the risk of diabetes in people with low arsenic concentrations in their urine compared to people with even lower levels.
