“…Average phase percentages were about nine and 91 for particle and gas phases, respectively. This finding was similar to the reported values Green et al 2000;Simcik et al 1997;Foreman and Bidleman 1987). The detected congeners were mostly lower molecular weight congeners and they were in the gas phase.…”

Air samples were collected at a residential site (Gulbahce, Bursa, Turkey) between August 2004 and April 2005 using a modified high volume air sampler. The mean of gas and particle phase concentrations of polychlorinated biphenyls (PCBs) were 468 +/- 297 and 43 +/- 37 pg m(-3) (average +/- standard deviation, SD), respectively. The dominated PCB homologs were 3-CBs, 4-CBs, and 5-CBs. The measured PCB concentrations were higher than the values of pristine sites. In order to assess the gas/particle partitioning fate, log K(P)-log P(o)(L), log K(P)-log K (OA) and the Junge-Pankow model were applied to the data. Experimental K(P) was well correlated with log P(o)(L) and log K(OA) at p < 0.05. Then, dry deposition fluxes were estimated using atmospheric concentrations and dry deposition velocities obtained from literature. A correlation matrix was formed for PCB homologs including 27 congeners with concurrently measured 16 polycyclic aromatic hydrocarbons (PAHs) and meteorological parameters. Most of PAH compounds were significantly correlated with 5-CBs and 6-CBs.

“…A key parameter in the understanding of this long-range pesticide transport is the partitioning of the molecules between the gas and the particle phase of the atmosphere (G/P partitioning; Foreman and Bidleman 1987;Hoff et al 1992;Atkinson et al 1999), as this considerably influences the residence time of pesticides in air and their removal, for example by dry deposition according to their adsorbed fraction on particles. The atmospheric partitioning is largely influenced by processes linked to physico-chemical properties of the pesticides like the individual vapour pressure (Junge 1977;Pankow 1987) and by environmental parameters like temperature or humidity (Junge 1977;Yamasaki et al 1982;Chevreuil et al 1989Chevreuil et al , 1996Foreman and Bidleman 1990;Lane et al 1988;Finizio et al 1997;Sanusi et al 1999;Yeo et al 2003;Peck and Hornbuckle 2005;Sauret et al 2008).…”

Atmospheric particle (P) and gas (G) phase samples have been collected in Strasbourg (Northeast of France) using a high-volume sampler equipped with a filter-XAD-2 resin plug between April 17 and May 29, 2007. Seventy-one currently used pesticides were monitored in these samples, and 38 of them were detected at concentrations ranging from 0.07 ng/m 3 for fenarimol to 40.30 ng/m 3 for deltamethrin in the particle phase and from 0.03 ng/m 3 for fenarimol to 89.54 ng/m 3 for dimethachlor in the gas phase. These results were used to study the G/P partitioning of the pesticides using Junge-Pankow-based models, and to evaluate the influence of environmental parameters (temperature and humidity) on this partitioning. The average slope of log K P against log P 0 L was −2.11, suggesting that partitioning is influenced by adsorption. The partitioning equations also showed that the atmospheric concentrations of the monitored pesticides were dominated by volatilisations from local sources. Concerning environmental parameters, temperature was found to strongly influence the G/P partitioning of the studied pesticides while humidity has only very little influence on it.

“…The values of the saturation vapor pressures, usually at 25"C, were taken from Mackay and Shiu (1981) for the alkanes, the aromatic hydrocarbons (except styrene), naphthalene, 1 -methylnaphthalene, biphenyl, the chlorinated hydrocarbons, and chlorpyrifos. Equilibrium vapor pressures (20°C) for anthracene, phenanthrene, pyrene, and fluoranthene, as solids, and for chlordane, a liquid, were from Foreman and Bidleman (1987). Other vapor pressures were obtained from the CRC Handbook of Chemistry and Physics, 70th Edition (1989), Lange's Handbook of Chemistry (1985) (cyclohexylamine), or Hawley7s Condensed Chemical Dictionary (1987) (2-ethoxyethyl acetate).…”

The theoretical potential for the formation of clusters of vapor-phase organic compounds found in indoor air around the 218P00: ion was investigated as well as which compounds were most likely to form clusters. A compilation of measurements of indoor organic compounds has been made for future experiments and theoretical calculations by the radon research community. Forty-four volatile and semivolatile organic compounds out of the more than 300 that have been reported in indoor air were investigated. Water vapor was included for comparison. The results indicate that there is a potential for the formation of clusters of organic compounds around the 2 1 8~o 0 , f ion. The compounds with the greatest potential for cluster formation are the volatile oxidized hydrocarbons (e.g., n-butanol, phenol, hexanal, nonanal, henzaldehyde, the ketones, and the acetates) and the semivolatile organic compounds (pentachlorophenol, nicotine, chlordane, chlorpyrifos). Although the estimated diameters are consistent with the measured diameters for the "unattached" fraction, the state of experimental and theoretical knowledge in this area is not sufficiently developed to judge the quantitative validity of these predictions.
