“…3). The PAH concentration in aerosols was the most important factor, which directly affect the variation of the particulate deposition fluxes (Wania et al, 1998). The aerosols with higher concentrations of PAHs were found in the dry season, revealing that high aerosol concentrations induced high deposition fluxes.…”

“…According to Wania et al (1998), the distribution of semivolatile organic compounds between any sorbing surface materials (suspended aerosols or any earth surface, e.g. soils, plants, bedrocks, water) and air depends mainly on temperature.…”

8Gas-particle partitioning of pollutants is an important mechanism determining 9 atmospheric processing and its impact to environmental and human health. In this 10 paper, the gas-particle partitioning of polycyclic aromatic hydrocarbons (PAH) has been 11 studied with the aim of determining the main mechanism of PAH partitioning in 12 Zaragoza (Spain) aerosols. To reach this goal, the ambient concentrations of PAH (gas 13 and particle phase) collected in this city for one year period (2003)(2004) have been 14 analyzed. 15The partitioning between the particle and gas phases was studied according to three 16 different models: the Junge adsorption model, the absorption into the organic matter 17 model using the octanol-air (K OA ) partition coefficient and the absorption into the 18 organic matter plus the adsorption onto the soot carbon model using the soot-air (K SA ) 19 partition coefficients. 20Experimental gas/particle partition coefficients (K P ) correlated well with the subcooled 21 liquid vapour pressures (P 0 L ) of PAH but with slopes higher than the expected value of -22 1. Experimental Kp values were well fit to the modelled ones when, in addition to 23 absorption into organic matter, adsorption onto the soot carbon was considered. It could 24 be concluded that the main partition mechanism in Zaragoza aerosols was explained by 25 adsorption onto the soot carbon. However, Kp modelled values were affected by the 26 different thermodynamic parameters related to soot types. 27The influence of the organic matter and elemental carbon fractions on the Kp modelling 28 was also studied. The different particle characteristics, local factors, the presence of non 29 exchangeable fraction and non equilibrium were considered like main keys to explain 30 deviations of the experimental Kp values from predictions according to models. 31 32

“…The air-water interface plays a key role in the exchange and distribution of persistent organic pollutants (POPs) and has to be taken into account when their environmental fate and budget calculations are investigated (Wania et al, 1998). In the first 50 lm over 20 properties such as the concentration of suspended particles, density, pH value, complexing capacity and so on change sharply (Zhang et al, 2003a); these unique characteristics contribute to an increase in the interfacial effect of the sea microlayer, which features a unique chemical composition (high content of lipids, fatty acids and protein) that leads to its capacity for accumulating hydrophobic organic pollutants, which may be transferred to the air via volatilisation or bubble bursting.…”

Polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) are two classes of micropollutants intensively monitored and regulated due to their toxicity, persistency and wide diffusion. Their concentrations have been investigated in sea-microlayer (SML) and sub-surface water (SSW) samples collected at two sites of the Venice Lagoon, a fragile ecosystem highly influenced by industrial and anthropogenic emissions. The total P PCB concentration varies from 0.45 ng/l to 2
