Mercury fumes can cause damage to the central nervous system. Clancy can find as little as half a gram of mercury and protect students and teachers from prolonged exposure. (Check out the video.) Clancy works with Carol Hubbard for the the Minnesota Pollution Control Agency as part of the Mercury-Free Zone Program.
Clancy’s health isn’t overlooked either. To protect Clancy, his blood is checked for mercury every three months and it has always been below detection levels.
