a  TOC = 0.83 ± 0.03%; black carbon = 0.258 ± 0.056%; arochlor 1254 PCB concentration = 330 (μg/kg). Data taken from ref (14).
b  Crab Orchard Lake sediment: TOC = 0.59%; the sediment comprised 16% clay, 70% silt, 14% sand; arochlor 1254 PCB concentration = 29153 (μg/kg); PCB congener mass fractions desorbed within 14 days ranged from 40 to 80%; black carbon % was not determined. Data taken from ref (12).
c  Data taken from ref (13).
d  Data taken from ref (2).
e  Data taken from ref (14).
f  Black carbon was taken as 29% of TOC which was estimated based on the average BC/TOC ratio for 6 samples described by Cho et al. (18) taken from an adjacent location in the same mudflat where the original HP sediment was sampled.
