Thus, the PFA components represented on average ~50% of the total mass on the sampling filters. The correlation between the total mass on the filters and the summed masses of PFAs and HCs was high (Pearson’s R = 0.99; P
Thus, the PFA components represented on average ~50% of the total mass on the sampling filters. The correlation between the total mass on the filters and the summed masses of PFAs and HCs was high (Pearson’s R = 0.99; P < 0.01) (Fig. 3).
