Iv. sulphate concentrations in air and precipitation and acid deposition.
Recycling water from the system was characterized with high salt content, high chloride and sulphate concentrations.
Sulphate concentrations in runoff water have generally decreased and pH increased.
Regional trend analyses of the chemical status of surface water for ICP Waters sites show that sulphate concentrations are decreasing at almost all sites.
Sulphate concentrations in air and precipitation have decreased throughout Europe.
On around 45% of all evaluated plots a significant decrease in sulphate concentrations was recorded and there were hardly any plots with a significant increase 0.4.
Sulphate concentrations were the highest on plots in Eastern Europe and Belgium.
The trend has been decreasing, though: The SO 2-emissions have been reduced by 75% between 1979 and 2006, and the sulphate concentrations have been reduced by 37% between 1986 and 2008.
Decreasing sulphate concentrations emphasize the importance of nitrate as the second important acidifying anion.
This is particularly evident in terms of improvements in surface water quality,specifically related to an almost universal decrease in sulphate concentrations in lakes and streams.
Decreases in sulphate concentrations are nearly universal, and have been throughout the period of record table.
Of the 34 sites with sufficient data for trend analysis of bulk deposition,all sites had a downward trend in sulphate concentrations and the trend was statistically significant at 28 sites for the period 1993- 2006.
Sulphate concentrations were decreasing, while nitrate trends showed no consistent regional pattern.
In Europe, S deposition correlated positively with aquatic sulphate concentrations, and high total N deposition(>15 kgN ha- 1 a- 1) correlated positively with nitrate(NO3) concentrations. .
Sulphate concentrations in deposition and runoff and soil water were generally decreasing as a response to decreasing deposition.
Are base cation concentrations changing in response to declining sulphate concentrations in surface waters, and are the changes consistent with potential recovery from acidification?
The sulphate concentrations are higher and the alkalinity is lower than in the Paatsjoki River, and there is a marked decrease of alkalinity in the spring.
The most significant finding in the regional trend analysis carried out by ICP Waters is the almost universal decrease in sulphate concentrations in lakes and streams in regions throughout Europe and North America.
Changes in sulphate concentrations in deposition and stream water in 1988-2000 at the ICP Integrated Monitoring site Birkenes, southern Norway.
The most significant finding in the regional trend analysis, as in others conducted on earlier data(,),is the almost universal decrease in sulphate concentrations in lakes and streams throughout Europe and North America.
The large declines in sulphate concentrations seen at many of the sites were well captured by the model, as were the observed increases in acid neutralizing capacity ANC.
A region-wide recovery of surface waters from acidification in Europe and North America was documented in the late 1990s,indicating that sulphate concentrations were decreasing and that alkalinity concentrations and pH showed positive trends in most regions.
The trends of sulphate concentrations over 1993- 2003 showed decreasing trends in deposition for more than half of the studied sites; the generally decreasing trends in runoff and soil water were a response to decreasing deposition.
Mr. M. Forsius(Finland), Head of the Programme Centre of ICP Integrated Monitoring,reported that sulphate concentrations in deposition and runoff and soil water were generally decreasing as a response to decreasing deposition in the period 1993- 2003.
Sulphate concentrations in surface waters respond rapidly to changes in S deposition. Typically, 90% of incoming N deposition is retained by the catchment soil, but moderate to high N deposition leads to elevated NO3 concentration in runoff.
Regional trend analyses of surface water chemistry sites of the International Cooperative Programme on Assessment and Monitoring of Acidification Rivers and Lakes(ICP Waters)show that sulphate concentrations are decreasing at almost all sites, and in almost all cases the decreases in the 1990s are larger than those of the 1980s.
As a consequence of decreased sulphur deposition, the sulphate concentrations in runoff water declined at most sites in Nordic countries between 1988 and 1995; here, decreasing nitrate concentrations are also commonly observed.
Regional trend analyses of surface water chemistry sites of the International Cooperative Programme on Assessment and Monitoring of Acidification Rivers andLakes(ICP Waters) show that sulphate concentrations are decreasing at almost all sites, and in almost all cases the decreases in the 1990s are larger than those the of the 1980s.
Forecasting water quality at the end of operations suggests that there is a likelihood that sulphate concentrations at the EMZ will routinely exceed 500 mg/L. However, it should be noted that sulphate at these concentrations is non-toxic to aquatic organisms and the levels anticipated do not pose a serious threat to degradation of water quality in the Kumtor River.”129 In our opinion, the Commission's sampling results do not contribute new information that is not already disclosed by Kumtor.
Important results of the regional trend analyses are that sulphate concentrations are decreasing at almost all sites, and in almost all cases the decreases are larger in the 1990s than in the 1980s.
