Scientists solve riddle of toxic algae blooms
Continue to the storyAfter a remarkable 37-year experiment, University of Alberta scientist David Schindler and his colleagues have finally nailed down the chemical triggers for a problem that plagues thousands of freshwater and coastal ecosystems around the world.
By pumping various pollutants into Lake 227, a small pristine lake in the Experimental Lakes region of northern Ontario, they were able to pin down which chemical nutrients were key to triggering the blooms.
"Phosphorous really is the key," says Schindler, whose study is highlighted in the U.S.-based Proceedings of the National Academy of Sciences this week.
