Low levels of arsenic is not associated with higher blood pressure

While arsenic in water, food, health is a concern, a new study suggests the levels found in most Americans are too low to increase the risk of high blood pressure.

Earlier research has linked high levels of chemicals to increase blood pressure, lung cancer and other diseases, so the new findings, published in the Journal of Epidemiology, and provide some reassurance.
A limitation of the study, however, is that people surveyed in one point in time, instead of following them over time to see who developed high blood pressure.

“It` s too early to say, `There` s nothing to do, you `re safe,` “said researcher Dr. Ana Navas – old, of the Johns Hopkins School of Public Health in Baltimore.
Even if most Americans `arsenic levels aren ‘t high enough to raise blood pressure, and added that there is still other health risks, such as diabetes.

“I think we` re learning more about the possible health effects of low levels of exposure, “said Navas – the old one. “But we still need to make evaluations more risk.”

Arsenic found in the element, rock, soil, water and air. Also released into the environment through industrial activities, and can be found in products such as dyes, paints and fertilizers.
Studies have linked from Asia and South America, chronic exposure to arsenic through drinking water to high blood pressure, lung disease, but the water was there high concentrations of arsenic – upward of 100 micrograms per liter.

In the United States, the limit is 10 micrograms per liter, and most of the United States drinking water supplies have significantly lower levels than that.

Health effects such as exposure to low to medium is not yet clear.

On the current study, used Navas – old colleagues and government survey data from the ongoing health of the sample nationally representative of adults in the United States. They focused on nearly 4200 men and women who `d given urine samples to measure arsenic.

Overall, it was found 36 percent of the study group that the high blood pressure. There was no association, however, among the participants `arsenic levels and risk of high blood pressure.
But the researchers warn that exposed some Americans are still high levels of arsenic are relatively through drinking water – especially in certain areas of the West, Midwest, New England, where the groundwater contains high concentrations of toxic chemicals.

It is estimated that 13 million Americans live in areas where the public water supply exceed the threshold of 10 micrograms per liter. And possibly unregulated private wells also contain a lot of arsenic.
“A lot of people who live in areas with high levels of arsenic in groundwater wells may,” said Navas – the old one. And recommended that people in these areas and well water tested.

If the level of arsenic exceeding 10 micrograms per liter, can handle the water well with filtration systems designed to remove contaminants.
