Description

Reports the results of a study that examined the performance of Alberta Environment’s inference model relative to the Environment Canada model for predicting dry deposition in Alberta and used this performance comparison to recommend changes for a number of assumptions and boundary conditions in the Alberta inference model to improve its performance.

Description

Currently there is no standard method for field measurement and estimation of dry deposition of acidifying pollutants in Alberta. Alberta Environment is pursuing development of an inexpensive standard method. This may involve a combination of continuous, intermittent, and/or passive field measurements of acidifying pollutants and using inference methods for estimating sulphur and nitrogen species dry deposition. An overall objective of this study was to continue evaluating inferential methods for estimating dry deposition rates.

Environmental levels of polychlorinated dibenzodioxins and dibenzofurans in ambient air at selected monitoring sites in Alberta

Description

This report presents the levels of polychlorinated dibenzodioxins and dibenzofurans (PCDD/PCDF) in ambient air as measured during the 1997 and 1998 sampling years at selected sites across Alberta.
