Atmospheric polychlorinated biphenyl (pcb) inputs to a coastal city near the Marmara Sea.
Recent studies have shown that polychlorinated biphenyl (PCB) levels are high in coastal sites. Various types of deposition events, including dry deposition, air-water exchange and wet deposition, were analyzed as part of the study to illustrate the pollution level. The atmospheric levels and deposition mechanisms of 82 PCBs were investigated in Mudanya, a coastal city in Turkey. A total of 175 samples and 112 blanks were collected. Air-water exchange and particle phase dry deposition fluxes were 120 ± 90 ng/m(2)-d and 125 ± 160 ng/m(2)-d, respectively. The wet-dry deposition sampler (WDDS) consisted of two reservoirs, wet and dry. Collected with the WDDS, the dry deposition flux was 21 ± 20 ng/m(2)-d, and the wet deposition fluxes (during the rainy period) were 145 ± 130 ng/m(2)-d and 195 ± 270 ng/m(2)-d for the dissolved and particulate phases, respectively. Mass transfer coefficients (MTCs), dry deposition velocities and washout ratios were calculated and compared with the literature values.
