- W2295382013 abstract "Wet deposition measurements from various monitoring networks in Canada and the US were combined and integrated to estimate the total mass of non-sea-salt sulfate, nitrate, H{sup +} and cations (Ca{sup ++} + Mg{sup ++} + K{sup +}) wet deposited annually to eastern North America. The results showed that the integrated wet deposition of sulfate and cations (Ca{sup ++} + Mg{sup ++} + K{sup +}) decreased markedly from the early 1980s to the early 1990s while the integrated nitrate and H{sup +} deposition did not. It therefore appears that the decrease in the integrated cation deposition offset the decrease in sulfate, resulting in little change to the integrated deposition of free acidity. The same conclusion was obtained from a long-term trends analysis of precipitation chemistry data from 16 sites across eastern Canada. A geometric trends model was fitted to daily ion concentrations in precipitation. The long-term trends indicate that sulfate concentrations in precipitation decreased significantly from the early 1980s to the early 1990s at 12 of the 16 sites, mostly between the early 1980s and the mid-to-late 1980s. Concurrent with these decreases were declining base cation concentrations at 12 of the 16 sites and constant or increasing nitrate concentrations at 9more » of the 16 sites. As a result, the concentration of hydronium ion in precipitation remained constant at 8 of the 16 sites and varied between increasing and decreasing trends at the other sites. A similar time series analysis of CAPMoN ambient air data showed that concentrations of sulphur dioxide decreased significantly from the beginning of the 1980s to the beginning of the 1990s at 5 of the 6 sites where long enough data records were available. Similar but less consistent trends were found in the case of sulfate. Vapor phase nitric acid concentrations showed increasing long-term trends over the same period.« less" @default.
