Soil carbon pools and fluxes following the regreening of a mining and smelting degraded landscape.

Increasing forest cover by regreening mining and smelting degraded landscapes provides an opportunity for global carbon (C) sequestration, however, the reported effects of regreening on soil C processes are mixed. One of the world's largest regreening programs is in the City of Greater Sudbury, Canada and has been ongoing since 1978. Prior to regreening, soils in the City of Greater Sudbury area were highly eroded, acidic, rich in metals, and poor in nutrients.

The impact of severe pollution from smelter emissions on carbon and metal accumulation in peatlands in Ontario, Canada.

Peatlands are unique habitats that function as a carbon (C) sink and an archive of atmospheric metal deposition. Sphagnum mosses are key components of peatlands but can be adversely impacted by air pollution potentially affecting rates of C and metal accumulation in peat. In this study we evaluate how the loss of Sphagnum in peatlands close to a copper (Cu) and nickel (Ni) smelter in Sudbury, Ontario affected C accumulation and metal profiles.

Effectiveness of a medication discharge plan for transitions of care from hospital to outpatient settings.

Purpose: The effect of a medication discharge plan (MDP) on the rate of medication discrepancies between hospital and outpatient settings was evaluated.

Methods: In a pragmatic, open, randomized, controlled trial, MDPs were completed for all patients before discharge from the hospital. Patients were then assigned to either an MDP group, for whom MDPs were sent to community pharmacies and treating physicians, or a usual care group, for whom an MDP was not sent.
