摘要：

Investigation into the impact of anthropogenic acidic precipitation may be hampered by the presence of alternate sources of acidity. A study of the contributions of sulfate anions versus organic acid anions was made on 20 lakes and wetlands near Killarney, Ontario. This area is near North America's largest single source of sulfate emissions. Charge balances were constructed for each of 47 water samples. These showed that sulfates contributed far more than did organic acids to the acidity of these waters. On average, the concentration of sulfate anions was 31. 6 times the concentration of organic acid anions. The available evidence suggests that the sulfate was from anthropogenic rather than geological sources.
