Diabetes: Arsenic in Water Supply Linked to Type 2 Diabetes

By:

A recent analysis of government data is the first to link low-level arsenic exposure, from drinking water with type 2 diabetes, researchers say. Arsenic is an industrial pollutant that can also get into drinking water naturally when minerals are dissolved.

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.

An analysis of 788 adults’ medical test found nearly four times as great increase in the risk of diabetes in people with low arsenic concentrations in their urine when compared with people with even lower levels.

High Levels of arsenic in drinking water with diabetes have been linked by researches done outside the United States. It’s the link at low
levels that’s new.

The findings appear in Wednesday’s Journal of the American Medical Association.

The United States lowered arsenic standards for
public water systems to 10 parts per billion in 2001 because of known
cancer risks. Compliance was required by 2006, years after the study
data were collected in 2003 and 2004.
