The Southwest Clean Air Agency has conducted some localized studies analyzing ambient air toxics in Vancouver and Longview, Washington. For more information about these studies, call the Southwest Clean Air Agency at 360-574-3058.
Air Toxics Study at St. Helens Elementary School - Longview
EPA found air toxics concentrations are below the levels of concern associated with health problems from short-term or long-term exposures to acetaldehyde, manganese, and nickel or other toxic metals. While the results confirm some impact from a nearby source, the monitored results are not as high as was suggested by the modeling data. Because no concentrations of concern were found, monitoring has been discontinued at the school. Read more about the study at www.epa.gov/schoolair.
