Don't drink the water? Arsenic linked to cardiovascular risk...

Arsenic in water linked to cardiovascular risk"We need more cardiologists to be thinking about environmental effects on the heart...It’s not just some abstract E.P.A. problem. It’s actually affecting our patients."

~Dr. Gervasio Lamas, Chief of Cardiology at Mount Sinai Medical Center, Miami, FL

This NY Times post features an epidemiological study that highlights the cardiovascular impact of low-level arsenic exposure in drinking water over a 6-7 year period in Bangladesh.

The study was conducted on almost 12,000 subjects and the major conclusion was that even low levels of arsenic exposure have an adverse association with mortality related to heart disease. 

Yikes.

The reality is that the impact of environmental exposures—in water, soil, and air, for example—are still poorly understood and poorly measured, in large part because it is hard to run controlled longitudinal, population studies.   This is an incredibly important area of future research.
