- In response to a fall of 71 per cent in sulphur dioxide emissions between 1987 and 2001, dry sulphur deposition fell by 74 per cent and wet sulphur deposition by 45 per cent.
- Recent sulphur emissions reductions have been accompanied by improvements in lake water chemistry, although it is too soon to be sure if this represents a sustained trend.
