Region-Specific Associations between Environmental Factors and in Freshwater Beaches in Toronto and Niagara Region, Canada.

Poor freshwater beach quality, measured by () levels, poses a risk of recreational water illness. This study linked environmental data to geometric means collected at 18 beaches in Toronto (2008-2019) and the Niagara Region (2011-2019) to examine the environmental predictors of . We developed region-specific models using mixed effects models to examine as a continuous variable and recommended thresholds of concentration (100 CFU/100 mL and 200 CFU/100 mL).

Changes in quality of life and perceptions of general health before and after operation of wind turbines.

Ontario is Canada's provincial leader in wind energy, with over 4000 MW of installed capacity supplying approximately five percent of the province's electricity demand. Wind energy is now one of the fastest-growing sources of renewable power in Canada and many other countries. However, its possible negative impact on population health, as a new source of environmental noise, has raised concerns for people living in proximity to wind turbines (WTs).
