A comprehensive workflow for suspect screening and non-target screening with gas chromatog. coupled with quadrupole time-of-flight mass spectrometry (GC/QTOF-MS) was used to characterize the pollution characteristics of soil samples in a typical coking plant in China. Suspect screening confirmed 57 chems. including PAHs, alkyl PAHs, and phthalates contained in high-resolution personal compound database and library (PCDL). Non-target screening detected 88 chems. from soil samples in the NIST 17 library. A total of 122 chems. were screened in soil samples, and many of them were of emerging concern. Their presence in the soil obtained from coking operations was underestimated, such as the oxygenated PAHs (naphtho[2,1-b]furan and 9H-fluoren-9-one), and the alkyl biphenyls compounds (4,4¡ä-dimethylbiphenyl, 3,3¡ä-dimethylbiphenyl, 4-methyl-1,1¡ä-biphenyl and 2,2¡ä,5,5¡ä-tetramethyl-1,1¡ä-biphenyl). Toxicity assays by luminescent bacteria proved that the extracts from soil samples at different depths showed varying toxicity to V. qinghaiensis sp.-Q67. Soil extracts from a depth of 20-40 cm exhibited the greatest toxicity to luminescent bacteria compared with the other six-layered soil samples, which was correlated with the number of detectable pollutants and total organic carbon content. This study provided a screening method for suspect and non-target contaminants in urban industrial soil sites, which was important in identifying localized contamination sources.
