The concentration of short-chain polychlorinated paraffins (SCCPs) in the urban air of Dalian, China was monitored from September 2016 to August 2017 with a self-developed passive sampler (PAS1) and an activehigh-volumesampler, simultaneously. PAS1 successfully collected theentire targetSCCPs intheambientair.AirSCCPs sampledby PAS1were foundbe inthe linear uptake stage during 181 days of sampling. Passive and active samples showed comparable congener profiles, and the dominant contributors of SCCPs in the two kinds of samples were similar. A significant linear correlation was observed between the total concentration of SCCPs sampled by PAS1 and active sampler in the four seasons. The passive sampling rates of the PAS1 for thegas andparticulate phasesof SCCPsweremeasured.The quantitative structure-property relationship of the sampling rate of PAS1 (Rair) for gas-phase SCCPs was studied. From the molecular point of view, Rair wasmainly affected by themolecularweight and sub-cooled liquid vapor pressure of SCCPs. In general, SCCPs intheurbanair ofDalianmainly existedingas phase, lower molecular weight SCCPs primarily occurred in the gas phase, whereas higher molecular weight SCCPs were predominately adsorbed or absorbed on airbe particles. The air concentration of SCCPs in the four seasons were different, the correlation of the concentration of SCCPs inthe air withthemeteorology parameterswas conducted.Theexposure risk by intake air SCCPs of the residents around the sampling sites was evaluated according to the European risk assessment standards.
