Cutting mercury inputs to lakes quickly reduces mercury in fish, say scientists

"Carried out at the IISD Experimental Lakes Area (IISD-ELA) in Ontario, Canada, one of the only facilities in the world where lakes and their watersheds can be experimentally manipulated to determine the many ways in which humans are impacting lakes, the 15-year study tracking the impacts of mercury inputs to lakes on freshwater fish discovered that while mercury quickly built up in fish populations, it also declined almost as quickly once mercury additions stopped."

Fish health improves when mercury releases into lakes cut off

"Mercury contamination in freshwater fish populations falls quickly once new sources of the toxic chemical are cut off, says new research. Paul Blanchfield, lead author of the study published in the journal Nature, said the finding that lakes can rebound quickly from mercury pollution is good news."
