“…For example, fine fraction of FLN was 50% for both sites while the fine fractions of BghiP were 90 and 97% for Industrial and Urban sites, respectively. Similar results were reported in the literature (Offenberg and Baker, 1999;Kaupp and McLachlan, 2000;Lammel et al, 2010). The percent distributions of PCBs and PBDEs in fine PM were ~60 and it was up to 80 for OCPs (Fig.…”

Particle size is an important parameter in terms of human health effects, fate and transport of pollutants associated with particulate matter (PM). Persistent organic pollutant (POP) (i.e., PAHs, PCBs, PBDEs, and OCPs) concentrations were measured on fine (d p < 2.5 µm) and coarse (2.5 µm < d p < 10 µm) aerosol samples collected at two (Urban and Industrial) sites in Izmir, Turkey. POP concentrations were ~2 times higher at the Industrial site due to the local sources (i.e., scrap processing iron-steel plants, ship-breaking activities, a petroleum refinery, and a petrochemical plant) that were recently shown to be hot spots emitting these pollutants. The size distribution of particle-phase POPs indicated that they were mostly (> 50%) associated with fine PM. The larger contribution of all POP compounds to fine PM could be attributed to the higher sorption capacity of fine PM because of its relatively higher organic matter content compared to coarse PM. Fine PM fraction of POPs significantly increased with octanol-air partition coefficient (K OA ) (p < 0.01) since larger K OA values favor the partitioning of POPs to PM. Relationships between fine PM percent and meteorological parameters (i.e., temperature and wind speed) were also investigated. Fine PM percent decreased with temperature and the correlations were significant for 51% of the compounds (p < 0.01), suggesting that the decrease in K OA with increasing temperature results in less partitioning to PM. Fine PM fraction also decreased with wind speed (p < 0.01 for the 52% of the compounds) that could be attributed to increased resuspension of contaminated coarse particles with increasing wind speed. Using the experimental deposition velocities reported for several POPs in the study area it was shown that dry particle deposition velocity significantly decreases with increasing fine PM fraction (p < 0.01). This indicates that the increase in fine fraction of POPs with decreasing volatility may have important implications for their environmental fate and transport.

“…The limit of quantification (LOQ) needs to take the accuracy of the blank level into account. Lacking a measure for the variation of the field blank, the relative standard deviation (SD) of field blanks from earlier field campaigns (σ c / b c ) on a highmountain site (high-volume sampling, summer 2007, n = 5; Lammel et al, 2009b) and in the Mediterranean (impactor sampling, summer 2008, n = 6; Lammel et al, 2010a) was used (σ = (σ c / b c ) × b). Identical samplers, sampling and analysis protocols for all analytes had been applied.…”

Air–sea exchange and gas–particle partitioning of polycyclic aromatic hydrocarbons in the Mediterranean

et al. 2014

Polycyclic aromatic hydrocarbon (PAH) concentration in air of the central and eastern Mediterranean in summer 2010 was 1.45 (0.30-3.25) ng m −3 (sum of 25 PAHs), with 8 (1-17) % in the particulate phase, almost exclusively associated with particles < 0.25 µm. The total deposition flux of particulate PAHs was 0.3-0.5 µ g m −2 yr −1 . The diffusive air-sea exchange fluxes of fluoranthene and pyrene were mostly found net-depositional or close to phase equilibrium, while retene was net-volatilisational in a large sea region. Regional fire activity records in combination with box model simulations suggest that seasonal depositional input of retene from biomass burning into the surface waters during summer is followed by an annual reversal of air-sea exchange, while interannual variability is dominated by the variability of the fire season. One-third of primary retene sources to the sea region in the period 2005-2010 returned to the atmosphere as secondary emissions from surface seawaters. It is concluded that future negative emission trends or interannual variability of regional sources may trigger the sea to become a secondary PAH source through reversal of diffusive air-sea exchange.Capsule: In late summer the seawater surface in the Mediterranean has turned into a temporary secondary source of PAH, obviously related to biomass burning in the region.Published by Copernicus Publications on behalf of the European Geosciences Union.

“…Despite the legal obligation, the state of monitoring is at a very low level and it is necessary to improve it in the Republic of Srpska [18,19], but there are significant research in the field of air pollution [20,21,22,23,24,25,13,26,18,19,20]. The present study aimed analysed concentration of SO 2 and investigate the relationship SO 2 with meteorological parameters, over the period from January -December 2016 in Banja Luka, Republic of Srpska, B&H.…”

Levels of SO2 in air samples from urban zone of Banja Luka were determined at locality Center inBanja Luka (administrative center of the Republic of Srpska, in Bosnia and Herzegovina) which ishighly populated area, with intensive traffic and industry. Through experimental measuring, daily andweekend variation of SO2 concentration was determined. Daily variations are directly connected toregime and intensity of traffic and using fossil fuels. The paper presents measured average values ofsulfur dioxide, together with max and min values and relationship between some parameters of airquality and meteorological parameters, i. e. for pollution modelling together with meteorologicalparameters.
