"Acid" in the Atmosphereby Dr Rick Leah
This is a complex subject area where there has a
very large amount of relevant research. Only a small proportion
of this can feature in the lecture. You should read
independently and widely.
You should understand the phenomena involved - how there are many
sources of pollutant which produce acidification of ecosystems.
You should understand how the complexity has interfered with
developing control measures but gain an appreciation of how far
control has been achieved.
In BIOL202 we are particularly interested in Transboundary Air Pollution so you should be able to put your knowledge into the context of:
The UK
Scandinavia and Europe
Continental North America

Useful notes for those with little time : Please click here for a link to some Short Background Notes based on
Overheads used in a previous Lecture given by Rick Leah on Acid Rain (This is not
exactly the same as presented in BIOL202 in 2004 but they could be used to prompt your
overall reading and understanding)
You are strongly advised to use the World Wide
web to scrutinise some up to date information and data.
These links should be of assistance but are by no means
comprehensive:
