Biodiversity is the delicate ecological balance within biological systems such as species and populations. Evidence suggests air pollution disrupts and impoverishes ecosysytems processes, and genetic and population diversity. Based on a symposium conducted by the EPA's Environmental Research Laboratory, this book pulls together current knowledge on the subject, assesses its relevance, and offers a framework for future research on the impact of air pollution on biodiversity through all levels of biological organization. This text is particularly timely due to acid rain and other toxic problems. The text also discusses the best available control technology, management practices, alternative chemicals, and legislative ways to reduce the impact of air pollution on biodiversity.

Drawing on literature reviews from ongoing unpublished research, research reports and symposia carried out on various aspects of the importance, ecology, biology and control of weedy rices, this publication also highlights global economic and environmental problems created by weedy rices, including red rice types.
