Polychlorinated dibenzo-p-dioxins and polychlorinated dibenzo-p-furans (PCDD/PCDF) congener profiles for 16 soil samples determined by gas chromatography/high-resolution mass spectrometry (GC-HRMS). The different samples are presented in the z-axis, in the following order, from back to front: 7, 12, 15, 17, 20, 29, 34, 37, 39, 40, 41, 42, 45, 46, 47, and 52. (a) The relative abundance of each congener obtained by dividing its concentration by the sum of concentrations of the 17 quantified congeners in each sample. (b) The percentage of toxic equivalent value (TEQ) contributed by each congener to the total TEQ value for each sample. Congeners: 2378-TCDF (1), 2378-TCDD (2), 12378-PeCDF (3), 23478-PeCDF (4), 12378-PeCDD (5), 234678-HxCDF (6), 123478-HxCDF (7), 123678-Hx-CDF (8), 123789-HxCDF (9), 123478-HxCDD (10), 123789-HxCDD (11), 123678-HxCDD (12), 1234789-HpCDF (13), 1234678-Hp-CDF(14), 1234678-HpCDD (15), OCDF (16), and OCDD (17). Congener acronym definitions are presented in the Materials and Methods section under GC-HRMS Analysis.
