A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

A practical book for professionals who rely on water quality data for decision making, this book is based on three decades experience of three highly published water and watershed resource professionals. It focuses on the analysis of air pollution sensitive waters and the consequent effects associated with soil and water acidification, nutrient-N enrichment, or the effects of atmospherically deposited toxic substances. It also covers lake zooplankton and/or stream macroinvertebrate biomonitors. Explanations of the reasons behind various recommendations provide readers with the tools needed to alter recommended protocols to match particular study needs and budget.

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.

The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.
