The Canadian Environmental Sustainability Indicators: on Population Weighted Ground-level Ozone

摘要：

From 1990 to 2005 the estimated increase in the population weighted ground-level ozone concentration trend,based on the lower-ends of the annual concentration data,was statistically more significant than the estimated increase in the trend based on the middle range of the annual concentration data.A trend analysis on the upper-ends of the concentration data did not reveal any statistically significant increase or decrease in the trend.Results of this hypothesis generating study indicate that as far as the national estimate to population weighted ground-level ozone concentration is concerned,the good days are getting worse and the bad days remain the same.
