Sulfur-Sulfate Trends for IMPROVE
Eldred R. 2001. Sulfur-Sulfate Trends for IMPROVE. CNL, University of California. Davis, CA
Warren White noted a trend in the ratio of nylon sulfate / Teflon sulfur over the course of the IMPROVE network. This is extremely critical in determining sulfate trends. This report concludes that there is no trend in the ratio of analytical calibrations, but there is a trend in the relationship at low concentrations. This is seen in the intercept and in distributions. The low end concentrations are primarily affected by the artifact that is subtracted from the samples. This change in low end concentrations can account for the trend in the ratios. No mechanism for producing such a change has been identified.
