This work draws together current research on the origins and effects of pollutants in the Artic area and the implications for arctic ecology and fauna as well as more far-reaching global change. Topics discussed include: toxic substances in the food chain; acids and heavy metals in snow and ice and the possible consequences to arctic ecology following snow melt; the Antarctic ozone "hole"; climate change and its effect on the northern hemisphere; climate and global sea levels; exploitation of minerals and fossil fuels; and future impacts from industrialization of the North. The book should be useful to all environmental scientists, atmospheric chemists, pollution specialists, ecologists, conservationists, climatologists, meteorologists and government and industrial departments concerned with environmental impact studies and pollution control.
