Pitt researchers use fluorescence to develop method for detecting mercury in fish http://apocadocs.com/s.pl?1227041730
Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. The technique involves a fluorescent substance that glows bright green when it comes into contact with oxidized mercury.... The intensity of the glow indicates the amount of mercury present.
Developed in the laboratory of Kazunori Koide, a chemistry professor in Pitt's School of Arts and Sciences, the new method can be used onsite and can detect mercury in 30 to 60 minutes for dental fillings (or amalgams) or 10 to 30 minutes for fish, Koide explained. "Our method could be used in the fish market or the dentist office," he said. "We have developed a reliable indicator for mercury that a person could easily and safely use at home."

The problem, of course, is what to do once you've seen that green glow.
