17-Year Acid Rain Experiment Alters Lake 223 Ecosystem Despite Water Recovery
Scientists conducted a 17-year experiment adding sulfuric acid weekly to Canada's Lake 223 to simulate acid rain effects. While the lake's water chemistry has since recovered, its ecosystem remains altered, with fish populations, especially lake trout, still below pre-experiment levels. The study highlighted acid rain's long-term ecological impact and informed air pollution regulations. Researchers are now exploring food-web restoration to aid ecosystem recovery, underscoring the challenges of reversing environmental damage despite chemical improvements.
