Sažetak
Total deposited matter includes dry and wet atmospheric deposition. For collecting deposition samples, different types of collectors can be used. The aim of this paper was to determine the influence of bulk collector performance on polycyclic aromatic hydrocarbon (PAHs) and polychlorinated biphenyl (PCBs) sampling efficiency. Two different bulk collectors were tested: an open cylindrical glass bottle with a diameter of 100 mm (BULK) and a glass bottle connected to a funnel with a diameter of 150 mm (BL). Sampling of biweekly bulk deposition samples was simultaneously performed during the BiREADI field campaign from 7 February to 10 July 2019 at the Martinska rural station located within the coastal zone of the Šibenik archipelago in the central part of the eastern Adriatic coast. The chemical analysis of 12 PAHs (fluoranthene, pyrene, benz(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(j)- fluoranthene, benzo(a)pyrene, benzo(e)pyrene, indeno(1, 2, 3-cd)pyrene, dibenz(a, h)anthracene and benzo(g, h, i)perylene) was performed using a gas chromatograph coupled to a tandem mass spectrometer operating in electron ionization mode (GC-EI/MS/MS). Six indicator PCB congeners (PCB-28, PCB-52, PCB-101, PCB-138, PCB- 153 and PCB-180) were analyzed by gas chromatograph equipped with two micro electron- capture detectors (GC-μECD) and two gas chromatographic columns. During the measurement period, the deposition fluxes (ng m-2 d-1) of Σ12PAHs varied between 12 and 459 for BULK and from 14 to 943 for BL, respectively. Furthermore, the deposition rates (ng m-2 d-1) of Σ6PCBs ranged between 9 and 44 for the BULK and from 5 to 13 for BL, respectively. The t-test showed a statistically significant difference (p < 0.05) in the deposition levels of PYR, PCB-28, PCB-52, PCB- 138 and Σ6PCBs for the different bulk collector performances. For the other PAHs and PCBs, there was no statistically significant difference (p > 0.05) in the deposition levels between the collectors. Fluoranthene, pyrene and chrysene were the major compounds detected, regardless of the performances of the bulk collectors. The largest contribution to the total mass of Σ6PCBs came from PCB-101 in BL and PCB-153 in BULK. From these results, it can be concluded that the performance of the bulk collectors can significantly influence the reported levels of PAHs and PCBs in atmospheric deposition samples.
