The purpose of this study was to compare a few passive samplers that may be used for non-target screening of organic chemicals in air and water. In this study we customized passive sampling and subsequent analytical methods. The methods were applied to three sites (S sites) as potential pollution hotspots and three reference sites (H sites). The number of the chemicals accumulated in polyurethane foam (PUF) in the pollution hotspots was greater than those in the control sites by more than a factor of two. Passive sampling was found to be less affected by the seasonal variations. In S3 site, the results of grab sampling showed significant monthly variations, suggesting the necessity of passive sampling. Up to 90,000 peaks were detected for each site as a result of analyzing of pre-treated samples with two-dimensional gas chromatography time of flight mass spectrometer (2D-GC/TOF-MS) after passive sampling. Especially, there were 800 to 1,800 chemical compounds screened under the condition that the similarity was over 700 and the signal-to-noise ratio was over 1,000. These results suggest that passive samplers would be useful in non-target screening of residual organic chemicals in air and water although further research is needed.
