24 h samples; EPA’s one in six day sampling schedule; 5/1/2006-4/30/2007 Carbonyls ATEC 2200 sampler DNPH cartridges EPA method TO-11A Particulate metals PM10 Hi-Vol. Quartz microfiber filters EPA method IO-3.5 Volatile Organic Compounds ATEC 2200 sampler canisters EPA method TO-15 Arsenic, beryllium, cadmium, chromium, lead, manganese, nickel Benzene, carbon tetrachloride, chloroform, 1,3-butadiene, 1,2-dichloropropane, methylene chloride, tetrachloroethylene, trichlororethylene,vinyl chloride Formaldehyde, Acetaldehyde
Nez Perce County Demographic Comparison Expect lower concentrations than in other U.S. data.
Potential Concern >50% detects exceed the chronic screening threshold Formaldehyde Acetaldehyde Benzene Carbon tetrachloride Tetrachloroethylene 1,3-Butadiene Arsenic Manganese
Chronic Inhalation Cancer Risk Comparison 30-year chronic cancer risk screening values from EPA Region 3 and highest annual mean concentrations from any site in the Lewiston study were used to generate estimated risk numbers.
Regional Comparison La Grande, OR May 2006-April 2007 rural NATTS site Longview, WA May 2004-May 2005 Pulp & paper, urban setting Seattle, WA 2005 Spokane, WA 2005
