We are planning to update our estimates for 2011 if new data become available. Check here periodically for information on identified trends in measured levels or factors related to exposure.

We searched for only publicly available data of measurements of MCPP in the Canadian environment. No systematic method for measuring data quality was possible, so we provide the following assessments of how well the data used may represent the actual Canadian average levels. Quality is rated higher when there are data from a number of Canadian monitors, or from Canadian studies that show results similar to other comparable studies. Quality is rated lower when data from few monitors or studies were available, and lowest when estimates are based on non-Canadian data. Others may rate data quality differently.
