Sammanfattning : Ozone is used in many applications in the industry as an oxidising agent for example for bleaching and sterilisation. The decomposition of ozone in aqueous solutions is complex, and is affected by many properties such as, pH, temperature and substances present in the water. LÄS MER
Sammanfattning : It is well established that air pollution has detrimental effects on both human health as well as the environment. Exposure to ozone and particulate matter pollution, is associated with an increase in cardiopulmonary mortality and morbidity. Asthmatics, elderly and children have been indicated as especially sensitive groups. LÄS MER
3. Ozonskiktet och risksamhället : En studie av den svenska politiska diskussionen rörande ozonskiktet 1968-1992
Sammanfattning : This thesis examines the development of the Swedish political discussion concerning the ozonelayer between 1968 and 1992. The analysis is based on the assumption that the threats against the ozone layer confronted the political system with an issue that called for new ways of thinking about environmental problems.

Sammanfattning : Several physical mechanisms concerning the impact of Rossby waves on ozone distribution and circulation in the stratosphere and troposphere are studied in the thesis.Summertime total ozone variability over Middle Asia and Northern Scandinavia shows similar wave-like behaviour with typical periods of 10-20 days and amplitudes of 20-50 Dobson units.

Sammanfattning : Ground-level ozone (O3) is a harmful air pollutant causing reduced crop yield and quality, reduced forest growth and negative effects on human health in large parts of the world. O3 is generally seen as a regional scale air pollution problem, but O3 concentration ([O3]) variation on a smaller geographical scale can be considerable. LÄS MER
