On-line data and reports on acid rain, atmospheric deposition and precipitation chemistry.

If you really want to be up to date, follow the links to the UK Report on TransBoundary Air Pollution : This contains a lot of seriously detailed evidence - good for seeing real data, analysis and explanation (A Tip: DON'T attempt to download the whole report unless you are on a very fast internet link! - its over 12 MB in size)

The Atmospheric Deposition Programme in the USA : http://nadp.sws.uiuc.edu/default.html
This is a consortium of organisations involved in doing acid rain research and includes links to the isopleth maps of Hydrogen ion deposition, SO4, NOx etc
Hint - use the .gif format for viewing any of the maps online - they print out on an inkjet ok as well

The USGS is the lead federal agency for the monitoring of wet atmospheric deposition (chemical constituents deposited from the atmosphere via rain, sleet and snow) in the United States.

Acid Rain has had significant impacts on Scandinavia, particularly Norway.

Emission Trading: Trading of Pollution Allowances

A favoured approach in America (and to some extent in Europe) is to set up a system where 'Allowances to Pollute' can be traded between interested parties. Only a restricted number of allowances are available (related to the capacity of the environment to absorb damage and Targets for improvement'. Interestingly, this shows strong signs of working and successfully puts some of the previously unattributed costs onto polluters.
