Book Description
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.

Book Description
This book presents updated and relevant information on the tropospheric ozone problem and its effects on the plants and human health. The contributions here present in-depth knowledge about history, pattern, sources, environmental factors and other necessary aspects of the tropospheric ozone problem. The book provides a balanced view of current developments on the effects of the tropospheric ozone on plant and human health, crop production and ecosystem services. In addition to the effects of the tropospheric ozone on growth and physiological and biochemical traits, it also considers the molecular basis of plant responses to ozone.

Book Description
Tropospheric ozone has long been recognized as a major environmental concern. Levels of ozone concentration have grown dramatically and the effects of ozone exposure have been examined in virtually thousands of studies worldwide. This timely new reference presents the state of the art in ozone regulation, human health effects, agricultural implications, and the economics of ozone reduction. Tropospheric Ozone guides you through the history of air pollution legislation and cites government initiatives to reduce ozone emissions. Ozone concentration data is supplied for a variety of geographic regions in examining the causes of ozone concentration and its potential effects on human populations, crops, and forests. Important issues such as crop yield, plant growth, and crop losses due to exposure are addressed, which will help develop an understanding of the economic implications of agricultural damage. New information is presented regarding risk assessment and human monitoring studies. EPA guidelines are reviewed, and potential health problems associated with ozone exposure are discussed in a practical, informative format. This valuable reference will benefit air pollution engineers, environmental consultants, government agency employees, regulators, industry professionals, health professionals, crop and soil scientists, environmental health and safety professionals, risk assessment professionals, and students in the environmental sciences.

Book Description
The research and its outcomes presented here focuses on tropospheric or ground level ozone, in particular due to its surfacing as a major threat to crop productivity around the world. This book presents the ozone concentration data for a variety of geographical regions, examines the factors responsible for its increasing concentrations and its potential effects on physiological and biochemical responses culminating in crop productivity losses which, in turn may pose a serious threat to global food security. Beside this, certain ameliorative measures that could be adopted to assess ozone injury in plants are also discussed. Global climate change scenarios predict a significant increase in future tropospheric ozone concentration. Particular attention is therefore given to evaluate the effect of global climate change on ozone concentrations. Readers will also discover how yield losses due to ozone are related to changes in the socio-economic conditions of the society, especially in South Asian regions. Students and researchers studying crop and soil science, environmental scientists, risk assessment professionals and policy makers will find this book of interest.

Book Description
The book contains information on geology, climate and vegetation of the Sierra Nevada with a special emphasis on air pollution effects on the mixed conifer forests. A history of the extent of air pollution effects on mixed conifer forests, especially ponderosa and Jeffrey pines is provided. The physiological basis for ozone-type injury development in ponderosa pine, a discussion of ozone uptake by plants at different levels of biological organization and the effects of air pollution and other stresses on mountain forests are discussed. A considerable portion of the book is dedicated to development of statistical models and maps of ambient ozone distribution in the Sierra Nevada based on the 1999 monitoring data with passive samplers. The implications of the methodological results, formulation and application of regional air quality models for integrated assessment of urban and wildland pollution and the need for functionally integrated models of ozone deposition to the Sierra Nevada forests are also discussed. Management and monitoring needs for improved long-term understanding air pollution effects on forest ecosystems, discussion of options for proper management of the air pollution affected forests, and comparison of monitoring and modelling of ozone and forest health status in the Sierra Nevada with similar efforts in mountains of North American and European mountain ranges are the focus of the later chapters of the book.

Book Description
Despite more than 20 years of regulatory efforts, concern is widespread that ozone pollution in the lower atmosphere, or troposphere, threatens the health of humans, animals, and vegetation. This book discusses how scientific information can be used to develop more effective regulations to control ozone. Rethinking the Ozone Problem in Urban and Regional Air Pollution discusses: The latest data and analysis on how tropospheric ozone is formed. How well our measurement techniques are functioning. Deficiencies in efforts to date to control the problem. Approaches to reducing ozone precursor emissions that hold the most promise. What additional research is needed. With a wealth of technical information, the book discusses atmospheric chemistry, the role of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) in ozone formation, monitoring and modeling the formation and transport processes, and the potential contribution of alternative fuels to solving the tropospheric ozone problem. The committee discusses criteria for designing more effective ozone control efforts. Because of its direct bearing on decisions to be made under the Clean Air Act, this book should be of great interest to environmental advocates, industry, and the regulatory community as well as scientists, faculty, and students.

Book Description
This document contains the scientific assessment of ground-level ozone effects. It begins with sections that provide background on atmospheric chemistry & reactions involving ozone, the gaseous precursors of ozone and their sources, and ambient ozone levels measured in Canada, their trends, & factors affecting those levels. The next four sections describe effects of ground-level ozone on materials, vegetation, birds & mammals, and human health as determined from epidemiological, exposure, and toxicological studies. This is followed by a section identifying reference levels for ozone, or those levels above which there are demonstrated effects. Finally, a risk characterization evaluates the evidence to determine whether the findings support a causal association between ground-level ozone and the noted effects.
