Stainless steel cages containing passive samplers were deployed in the water column in Istinye Bay, Istanbul Strait, and retrieved after 7 and 28 days. Collected samplers were analyzed using high-performance liquid chromatography (HPLC) to determine their PAH contents. Results showed that BR passive samplers have sampled all PAHs for both short- and long-term sampling periods while SPMD samplers only collected twelve and thirteen PAHs after 7 and 28 days, respectively. PDMS samplers showed the poorest performance, having only sampled seven and ten PAHs after 7 and 28 days, respectively. Among the BR samplers, a monophasic BR sampler with a single pore network (SN10) showed the most feasible performance in terms of PAH sampling and its preparation cost. Results highlighted that the SN10 sampler with a wide absorption range and monophasic structure can be used as an alternative passive sampler for pollution monitoring in marine environments.
