外文摘要：Across the three wintertime periods studied, remaining indoors appears to be an effective protective measure for Cache Valley wintertime PM2.5, with an approximate relationship of PM_(2.5)(indoor) = 20% PM_(2.5)(outdoor). The data have shown that a measureable fraction of this decrease is likely due to the revolatilization of particulate-bound ammonium nitrate back to its precursor components nitric acid and ammonia. However, it should be noted that some locations appeared to have other significant indoor PM2.5 and PM_(10) sources separate from potential outdoor infiltration (e.g. fireplaces, candles/incense, cooking, human activity, etc.), as increases in particle concentrations, particularly for the larger size fractions during hours of known activity.
