This study focuses on the feasibility of using a passive sampling device (PWSD) in marine environment. To evaluate this availability, PWSDs were deployed at seven sampling sites in Jinhae Bay for eight weeks. Four sites were in the open sea, and three sites were located in a semi-closed inner bay. To account for the adsorption losses caused by turbulence and biofouling during the sampling period, a performance reference compound (PRC) with a triolein adsorbent was spiked into a semipermeable membrane device (SPMD). The PRC recoveries were 40~78%, and the sampling rates were 2.2~7.9 L/day, as calculated using the SPMD Water Concentration Estimator v5-1 provided by the U.S. Geological Survey. The concentrations of polychlorinated biphenyls (PCBs) in PWSD were highly correlated (r = 0.962, p < 0.01) with those in the bivalves (Mytilus edulis) that were collected from the same sites where the PWSDs were deployed. However, the distribution patterns of the PCB homologues were slightly different between the PWSD and bivalves. Particles remaining in the gut of the bivalves may affect the relatively higher-molecular-weight PCBs (hexa- and hepta-). PWSD-converted PCB concentrations calculated using the SPMD Water Concentration Estimator v5-1 in the PWSDs were also highly correlated (r = 0.839, p < 0.01) with the average PCB concentrations in the seawater samples that were collected from the PWSD locations on the PWSD deployment and retrieval days. The results of principle component analysis and cluster analysis revealed different distribution patterns of the PCB homologues in the PWSDs, bivalves, and seawater.
