Artificial fluoridation of drinking water is commonly practiced in many industrialized nations. While precise numbers are unavailable, perhaps 400 million people living outside of the United States are located in areas where water is artificially fluoridated, according to the British Fluoridation Society. Untold millions of others, especially in parts of Africa, India and China, rely on water sources whose natural fluoride levels exceed EPA recommendations. Efforts to measure the amount of fluoride present in many of those areas are inconsistent and imprecise.
"This is a very significant public health issue worldwide," Saha said. "Some developing countries fluoridate their water but don't have a means for measuring it accurately. Others are drinking water that hasn't been treated with fluoride but that might already contain dangerous amounts naturally. Clearly there is a critical need for a fluoride sensor that can tell people whether their water supply is safe."
A paper describing his team's findings was recently published by the Journal of the American Chemical Society. "Fluoride Ion Sensing by an Anion-n Interaction" (http://pubs.acs.org/doi/abs/10.1021/ja107382x) was coauthored by Saha and his postdoctoral researcher, Samit Guha. It was also highlighted in the Dec. 6, 2010, issue of Chemical and Engineering News (http://pubs.acs.org/cen/).
