description: •Highest PAH concentrations were found in the mid-southern part of the YRD.•PAHs were from coal and biomass burning, petroleum spills, and/or vehicular emissions.•The PAHs in most sites were derived from the pyrogenic origin.•While the sites in the mid-southern part derived from the petrogenic sources.•The PAHs in soils in YRD were at low ecotoxicological contamination level. PAH concentrations of 61 surface soil samples collected from the Yellow River Delta (YRD), China were measured to determine occurrence levels, sources, and potential toxicological significance of PAHs. The total concentrations of ∑PAHs ranged from 27 to 753ng/g d.w., with a mean of 118±132ng/g. The highest concentrations was found in the mid-southern part of the YRD (753ng/g), which was associated with the oil exploration. The ratios indicated that the PAHs throughout the YRD were mostly of pyrogenic origin; while various sites in mid-southern part in the region were derived mainly from the petrogenic sources. Multivariate statistical analyses supported that the PAHs in surface soils of the YRD were principally from the coal and biomass combustion, petroleum spills, and/or vehicular emissions. The toxic assessment suggested that the PAHs in soils were at low potential of ecotoxicological contamination level for the YRD.
