Arsenic

From the CanWest News Service:
Pickering and her husband Graham George, also a U of S professor, along with University of Calgary chemist Juergen Gailer, have spent years questioning how to help as many as 80 million people in Bangladesh combat arsenic poisoning in drinking water.

Using a synchrotron in California, the team discovered that if arsenic and the element selenium are present in the body in equal amounts, they will bind with a naturally-occurring molecule and pass through the body harmlessly.

It isn't that Bangladesh people are arsenic-rich, George said, but that they're lacking the essential selenium.
Victims of arsenic poisoning are being given selenium supplements to see if it helps with their condition.
