Approximately 2700 - 6000 tons of mercury are released into the atm osphere every year. Once airborne, mercury can travel thousand of m iles from its generation point. Eventually, it precipitates onto th e land and water. And once it enters water, mercury is transformed by microorganisms into methylmercury, the most toxic and dangerous form of mercury. Methylmercury bioaccumulates most notably in fis h, increasing in concentration as it moves up the food chain. Nearly all fish contain trace amounts mercury, with certain fish co ntaining more than others. Once on the diner table, it creates a we ll researched danger to developing fetuses and young children. Rapi d and accurate testing is vital for public health.
