Uncertainties in source--receptor--effects relationships for acidic deposition between the Eastern U. S. and Southeastern Canada
The purpose of this paper is to integrate MOI work group results, to include the more recent data bases and results, and to evaluate the errors and uncertainties in each component of the source-receptor-effects relationships. The paper presents the strong geographic relationship between the areas of highest SO/sub 2/ emissions and wet sulfate depositions in eastern North America and the areas with significant loss of surface water alkalinity and excess sulfate in runoff in Ontario and Quebec Provinces. Analyses of air quality and precipitation chemistry data at the 5 MOI targeted sensitive receptors in southeastern Canada and basic climatology on transport and precipitation are used to make a general source region attribution for the observed SO/sub 2/ and SO/sub 4//sup 2 -/ concentrations and wet SO/sub 4//sup 2 -/ depositions. In addition the MOI transfer matrices to make a more specific source region attribution for the 5 targeted sensitive receptors in southeastern Canada and uses monitoring and lake runoff data to evaluate the uncertainties in the model simulations, including that for dry sulfur deposition. This also provides a summary of the conclusions and recommendations. Because of the large extent of the data bases and their analyses, it was necessary to organize them into an appendix to the paper which is available from the author. It should be noted that the paper does not deal with the matter of what should be the wet SO/sub 2//sup 4 -/ depositions to protect sensitive areas (i.e., target loadings) or what should be the SO/sub 2/ emissions to achieve those target loadings.
