Table 2.

Corrected concentrations for all runs and both replicates of 10 g crumb rubber and 5 g turf fiber samples. Numerical values reported for sample concentrations detected above the lower limits of quantification (>0.25 and > 0.27 ng/μL for 6:2 and 8:2 FTOH, respectively). <LLOD: sample concentrations were below the lower limits of detection (<0.36 and < 0.083 ng/μL for 4:2 and 6:2 FTOH, respectively).
