Abstract |
This report focuses on multi-pollutant concepts as they relate to our air quality management system. We focus on ozone, fine particles, and air toxics because these pollutants remain among the most persistent air quality problems affecting human health. However, we recognize that a multi-pollutant definition is far broader and should include coarse particles, sulfur dioxide (SO2), nitrogen oxide (NOx), and environmental concerns such as regional haze, deposition to ecosystems, stratospheric ozone protection, and climate change. With this report, we hope to facilitate a common understanding of multi-pollutant concepts to foster collaboration within and across the technical and policy disciplines throughout OAQPS; explore multi-pollutant analytic issues; and illustrate the initial development and implementation of a technical infrastructure to support a multi-pollutant approach to our programs. |
