| Short description: |
The MAGIC model has been calibrated for 12 sites in the UK using best available data. It successfully simulates observed changes in major ions and acid neutralising capacity over the period 1988 to 2000. Predictions for the future are made assuming deposition at current level compared to reduced sulphur and nitrogen emission agreed under the Gothenburg Protocol (significant reductions in sulphur dioxide, nitrogen oxides and ammonia by 2010). Uncertainty is assessed using best and worst cases of nitrogen leaching. The results support the need to reduce emissions in comparison with poresent day levels to prevent continued surface water acidification. If the requirements of the Gothenburg Protocol are achieved a recovery in acid neutralising capacity should occcur at all sites. Differences between ‘best’ and ‘worst’ case nitrate leaching are relatively small, emphasising the need to achieve the sulphur reductions in the shorter term. In the longer term further reduction of nitrogen emissions would be likely to be required.
