Decreased acid deposition and the chemical recovery of Killarney, Ontario, lakes

Article Abstract:

Research on Ontario, Canada's Killarney Park lakes indicates that many remain highly acidic despite improvement over several decades. As Sudbury metal smelters have reduced sulfur dioxide emissions significantly over the same time period, it is posited that sulfur deposition in this region is attributable to long-range transport.

Resilience of epilithic algal assemblages in atmospherically and experimentally acidified boreal lakes

Article Abstract:

Research on Ontario, Canada's Killarney Park lakes indicates that models of surface water ecosystem recovery from acidification should take into account the perturbation temporal and spatial scale and the biological delay responses. These factors may produce differences between acidification and recovery trajectories.

Assessing the recovery of lakes in southeastern Canada from the effects of acidic deposition

Article Abstract:

The article examines the effects of sulfur dioxide emissions reductions on aquatic ecosystems, using the Killarney Park lakes in Ontario, Canada, as an illustration. Findings suggest that significantly larger reductions in sulfur dioxide emissions will be required to produce biological recovery.
