Treatment effects on candidate markers. Two-way ANOVA of peak areas of the candidate markers, with time (0 h, 24 h) and exposure (clean air, EHC-93) as factors, showed significant time-dependent increases (0 h<24 h, p < 0.05) in P23, P113, P305 and P577 as well as a time-dependent decrease (0 h>24 h, p < 0.05) in P 715. Significant (p < 0.05) particle exposure effects were noted for P193 (air<EHC-93) and P1162 (air>EHC-93).
