Sulphur Emissions: Possible Effects of Reduced Norwegian Sulphur Emissions on the Fish Populations in Lakes in Southern Norway

摘要

Suggested restrictions on the sulphur content in oil used in southernmost Norway will probably reduce the sulphur deposition with about 4% in this area. It is estimated that the corresponding average increase in pH in lakewater will be about 0.02 pH units or somewhat less. This change is too small to give significant improvements in fish populations on a regional scale.
