Assessment of Air Quality and Air Pollutant Impacts in Class I National Parks of California

摘要

This report summarizes current and potential future conditions of air quality and air pollution impacts in Class I national parks located in California, and recommends monitoring and research activities that could be implemented to acquire critical new data. The subject parks include Joshua Tree National Park (JOTR), Lassen Volcanic National Park (LAVO), Lava Beds National Monument (LABE), Pinnacles National Monument (PINN), Point Reyes National Seashore (PORE), Redwood National Park (REDW), Sequoia and Kings Canyon National Parks (SEKI), and Yosemite National Park (YOSE). The focus of this report is on the effects of pollutants (ozone, sulfur dioxide, nitrogen oxides, particulates, sulfate, and ammonia) on air quality and on selected air quality related values (terrestrial vegetation, aquatic systems, visibility). Other pollutants (e.g., pesticides) are also discussed for specific locations where these pollutants may have potential impacts on natural resources.
