"People drinking water from private wells, which are not regulated, need to be aware that arsenic may increase the risk for cardiovascular disease. Testing those wells is a critical first step to take action and prevent exposure," coauthor Gernot Pichler said in a statement.
The team did acknowledge some limitations. They noted they had only one measure of arsenic exposure and did not have a long-term follow-up.
However, they believe their findings “are likely to be generalizable to millions of people in other rural locations exposed to low or moderate levels of arsenic in their water.”
They now hope their evaluations will encourage future studies on whether the changes are reversal. They also want to explore the potential health impact of reducing arsenic levels.
