ABSTRACT
The dramatic development of the acid rain phenomenon and its effects has generated an increasing awareness among the international community to the importance of fighting the type of environmental degradation. This chapter argues that the acid rain issue can only be addressed at a regional level; and that a convention, such as the Convention on Long-range Transboundary Air Pollution, is an ideal instrument for the international community. Sulphur dioxide and nitrogen oxides are the chief sources of acid rain. The main source of sulphur and nitrogen oxides is the combustion of fossil fuels for heat and electricity production and transportation vehicles. The group’s work comprises nitrogen oxides and tropospheric ozone and sulphur dioxide and the relevant supporting data, keeping in mind the requirements of the NOx protocol. Information on the role of nitrogen species in eutrophication and tropospheric ozone formation will be substantiated.
