Tropospheric ozone is a regionally distributed air pollutant that adversely affects both humans and vegetation. Surface-Level Ozone Exposures and Their Effects on Vegetation focuses on the formation, distribution, and transport of surface-level ozone; the characterization of its exposures; the mechanisms and processes involved in its deposition and uptake by plants; and its effects on the growth of crops and forest trees. State-of-the-art information is presented and the methodology for studying its effects on vegetation is critically reviewed. This background material leads to a discussion of the approaches for developing an air quality standard that will provide protection from the adverse effects of ozone, as well as suggestions for future research directions. Researchers and professionals in the utility industry, oil industry, and government environmental agencies; university instructors; and students will find that this book is filled with information that can be used on a daily basis in their work and studies.
