Liming of Acidified Surface Waters

Acidification is one of the most serious environmental problems, especially in Sweden, which suffers most from the consequences of acid rain. Besides international negotiations to reduce sulphur emissions - 85% of the acid load on Sweden can be traced to emissions from outside Sweden - the Swedish Government has employed large-scale operative liming activities to counteract acidification of surface waters. The scientific results show that - although acidification cannot be solved by liming - the measures taken resulted in substantially improved conditions in around 8,000 Swedish lakes and watercourses, and other countries affected by acidification may also profit from the Swedish experience.
