英文摘要	Local air pollution is one of the most pressing environmental problems in developing countries. The patterns of local air pollution are similar in many countries. In the initial stages of economic development the demand for energy, coupled to economic expansion, rises sharply. This increased consumption of power for heating electricity, industrial processes etc. must lead to an increase of emissions. Dust, SO2 and secondary products like sulphuric acid are responsible for severe impairments of human health and large scale damage to nature and buildings. Many developing countries have reached this stage of local air pollution or will be exposed to this type of environmental hazards in the near future. Economically developed countries, like the US, Japan and many countries in Western Europe have passed this stage one to three decades ago. In the next phase of economic development transportation, especially by means of lorries and cars becomes a determining factor in local air pollution and cause high concentrations of ozone, peroxyacetyl nitrate (PAN) and other oxidants are present as secondary products of traffic emissions. A number of developing countries are now entering the stage when this ''Los Angeles'' type of smog starts to become an important environmental problem. Developing countries should benefit from transfer of knowledge obtained in research programs and development of abatement policies in countries, which have been exposed to these problems in the past. But exchange of ideas between developing countries, regarding assessment of air pollution and implementation of emission controls is also very useful to derive optimal abatement strategies.; Chemistry, Multidisciplinary; SCI(E); 5
