Determination of Selected Polycyclic Aromatic Compounds in Particulate Matter Samples with Low Mass Loading: An Approach to Test Method Accuracy

Table 2

Max, min, and mean ratios estimated by taking PLE results as reference values. Relative standard deviation (sd) and statistic values () are also included for evaluating outlier data and whether the mean overall ratio was significantly different from 1.0. Tabulated two-side value () according to () freedom degrees is noted (). Empty cells correspond to outlier data or measured values below detection limits. Mean recoveries established by taking PLE results as reference values are noted in bold.
