Book Description
Historical and technical background is provided about ozone air pollution effects on ponderosa and Jeffrey pines in forests of the western U.S. The principal aim is to document the development of field survey methods to be applied to assessment of chronic ozone injury by government agencies responsible for management of forest and air resources, primarily in the Sierra Nevada and mountains of southern California. Detailed procedures are supplied for the selection of sample plots, collection of plot and tree data, computation of an injury index for each tree and execution of quality assurance procedures. Illustrated.

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
Six years of monitoring for ozone injury by the Pacific Northwest Research Station Forest Inventory and Analysis Program are reported. The methods used to evaluate injury, compute an injury index, and estimate risk are described. Extensive injury was detected on ozone biomonitoring sites for all years in California, with ponderosa and Jeffrey pines, mugwort, skunkbush, and blue elderberry showing injury. Little or no injury was detected in Oregon and Washington. The relation of observed injury to ambient ozone levels is discussed. The areas with the highest modeled risk of ozone injury are the areas east of Los Angeles, the southern Sierra Nevada, and portions of the central coast.

Book Description
A modern guide to environmental chemistry Chemistry of Environmental Systems: Fundamental Principles and Analytical Methods offers a comprehensive and authoritative review of modern environmental chemistry, discussing the chemistry and interconnections between the atmosphere, hydrosphere, geosphere and biosphere. Written by internationally recognized experts, the textbook explores the chemistries of the natural environmental systems and demonstrates how these chemical processes change when anthropogenic emissions are introduced into the whole earth system. This important text: Combines the key areas of environmental chemistry needed to understand the sources, fates, and impacts of contaminants in the environment Describes a range of environmental analytical methodologies Explores the basic environmental effects of energy sources, including nuclear energy Encourages a proactive approach to environmental chemistry, with a focus on preventing future environmental problems Includes study questions at the end of each chapter Written for students of environmental chemistry, environmental science, environmental engineering, geoscience, earth and atmospheric sciences, Chemistry of Environmental Systems: Fundamental Principles and Analytical Methods covers the key aspects and mechanisms of currently identified environmental issues, which can be used to address both current and future environmental problems.

Book Description
In 1994, the Forest Inventory and Analysis (FIA) and Forest Health Monitoring programs of the U.S. Forest Service implemented a national ozone (O3) biomonitoring program designed to address specific questions about the area and percent of forest land subject to levels of O3 pollution that may negatively affect the forest ecosystem. This is the first and only nationally consistent effort to monitor O3 stress on the forests of the United States. This report provides background information on O3 and its effects on trees and ecosystems, and describes the rationale behind using sensitive bioindicator plants to detect O3 stress and assess the risk of probable O3 impact. Also included are a description of field methods, analytic techniques, estimation procedures, and how to access, use and interpret the ozone bioindicator attributes and data outputs such as the national ozone risk map.

Book Description
The 1977 Clean Air Act legally mandated the prevention of significant deterioration (PSD) of air quality related values (AQRVs) on wilderness lands. Federal land managers are assigned the task of protecting these wilderness values. This report contains guidelines for determining the potential effects of incremental increases in air pollutants on natural resources in wilderness areas of the National Forests of California. These guidelines are based on current information about the effects of ozone, sulfur, and nitrogen on AQRVs. Knowledge-based methods were used to elicit these guidelines from scientists and resource managers in a workshop setting. Linkages were made between air pollutant deposition and level of deterioration of specific features (sensitive receptors) of AQRVs known to be sensitive to pollutants. Terrestrial AQRVs include a wide number of ecosystem types as well as geological and cultural values. Ozone is already high enough to injure conifers in large areas of California and is a major threat to terrestrial AQRVs. Aquatic AQRVs include lakes and streams, mostly in high elevation locations. Current sulfur and nitrogen deposition is probably too low to warrant immediate concern in most areas (with the exception of nitrogen deposition at some locations in southern California), although the low buffer capacity of many aquatic systems in California makes them sensitive to potential future increases in acidity. Visibility is considered as a discrete AQRV. Guidelines are presented for determining degradation of visibility based on sensitive views in wilderness areas. Estimates of current deposition of ozone, sulfur, and nitrogen are compiled for all California wilderness areas. Recommendations are included for resource monitoring, data collection, and decision criteria with respect to the disposition of permit applications.
