Oxidant air pollution impacts in the montane forests of Southern California
1999
Since the 1950s, the pines native to the San Bernardino Mountains in southern California have shown symptoms of decline that have been proved to result from exposure to ozone, a major plant-damaging gas in photochemical oxidant air pollution. Because of their proximity to major urban areas, the San Bernardino Mountains have served as a natural laboratory for studying effects of oxidant and acidic air pollution on a mixed-conifer forest. This volume presents a body of research conducted over more than thirty years, including an intensive interdisciplinary five-year study begun in 1991. Chapters include studies of the relationships of biography and climate to the region's air pollution the chemical and physiological mechanisms of ozone injury, as well as the impacts of nitrogen-containing pollutants and natural stresses on polluted forests. The synthesis of such long-term studies provides insights into the combined influences of pollutants on ecosystem function in forested regions with Mediterranean-type climates.

Assessment and control of nonpoint source pollution of aquatic ecosystems
1999
Thornton, J. A. (Jeffrey A)
"Why is nonpoint source pollution a problem? What topics are most important to the policy-maker? What are the characteristics of nonpoint source pollution? What factors affect its extent? What human activities and land uses are involved?" "These are among the questions addressed by a multi-national team of authors in this book. The aim is to review existing knowledge and experience regarding the assessment and control of nonpoint source pollution, and bring this knowledge together in a form that is useful for both scientific and management purposes. The book is not meant to be an extensive technical treatise, but rather to provide sufficient information to allow interested persons to acquire a broad, general knowledge of the assessment, causes and control of nonpoint source pollution."--Jacket.
