The study concludes that if mercury emissions from coal-fired power plants and other industrial activities were to be cut immediately, the amount showing up in fish would begin to go down within a decade.
It will appear in the Proceedings of the National Academy of Sciences of the United States of America online edition next week.
This breakthrough study (called METAALICUS - Mercury Experiment to Assess Atmospheric Loading in Canada and the United States) involved government agencies and universities on both sides of the border. It has global implications.
Study proves link between emissions and mercury pollution in fish
CANADA - A groundbreaking environmental study to be published in a prestigious American science journal proves that mercury atmospheric emissions will end up in fish in as little as three years. Biologists from the University of Alberta in Edmonton, Canada, played a key role in designing and carrying out the experiment.
