Effects of vegetation: native, crops, forests
Publisher Summary This chapter presents an update of research on the effects of air pollutants on vegetation. It discusses the primary data base for the two pollutants of primary concern to terrestrial ecosystems—ozone and sulfur dioxide. The chapter highlights research areas, discusses the relative importance of other pollutants, and covers some research areas that are receiving little attention at present. It focuses on two areas of critical worldwide interest. It is a synthesis of the understanding of the impact of acidic deposition on terrestrial systems. The chapter discusses the state of the art in regional and national assessment methodology, using an ongoing program as an example. It focuses on ozone and crop production and addresses research with sulfur dioxide and research on forest systems.
