The question to what extent primary and secondary air pollutants are relevant to atmospheric pollution and their effects on
human health and the quality of the environment can be answered in a straight-forward manner: atmospheric processes, including
oxidation procedures, particle formation and equilibria, determine the fate of primary emissions and, in most cases, the secondary
products of these processes are the more important ones concerning their effects on human health and the quality of the environment.
The formation of secondary products represents the critical property determining the establishment of certain air standards,
rather than the actually emitted substance, although there are notable exceptions. In this paper, a review concerning transformation
of primary pollutants as studied in the atmosphere of Athens is used to enlighten matters that may need further attention
by the responsible authorities and stakeholders for the control and reduction of atmospheric pollution. 相似文献
