Acidifying substances and tropospheric ozone. Effects and critical loads. Research programme for the period 1993/94-1996/97

摘要

This research program aims at strengthening the knowledge base needed for environmental work dealing with acidifying substances and tropospheric (ground-level) ozone at both national and international levels by: Assessing the risks for future forest damage and increased nitrogen leaching from forest soils, as well as the threat to biodiversity; Predicting the future acidification conditions for various deposition scenarios; Developing criteria for defining critical loads for sulfur, nitrogen, and tropospheric ozone in various types of natural ecosystems in Sweden; and Refining the concept of 'critical load' as a tool in environmental protection work.
