Abstract
⺠XRF is used to analyze Si and Al concentrations in ambient PM2.5 filter samples. ⺠Pure ammonium sulfate fine particles are added to the ambient filters. ⺠Si masses from XRF re-analysis are systematically higher. Al has large changes. ⺠Implication: IMPROVE Si and Al values have large uncertainties when S/Fe is high. ⺠Impacts 50% of IMPROVE data from 2002 to 2010.
