Table S1 presents the recoveries of mixed PAHs in the matrix spiked samples. The recovery was calculated based on three replicate injections on an Agilent GC-MS. Generally, the recoveries varied from 69.7% to 100.5%.

Table S2 shows the concentrations of 16 PAH (ng g−1 dws), diagnostic ratios and relative abundance of PAHs with different rings in surface sediments from the Yellow River dominated margin. The total concentration of 16 PAHs varied from 5.6 to 175.6 ng g−1 dws with a mean of 49.1 ng g−1 dws. The mean percentage of 2 + 3 rings, 4 rings and 5 + 6 rings was 60%, 29% and 11%, respectively. The mean value of Fla/(Fla + Pyr), BaA/(BaA + Chr) and IcdP/(IcdP + Bpe) was 0.55 (0.47~0.63), 0.29 (0.22~0.38) and 0.42 (0.24~0.49), respectively.
