Excerpt from
ANNEX XV TRANSITIONAL DOSSIER - CTPHT CAS 65996-93-2, SECTION B. INFORMATION ON HAZARD AND RISK, B.4.1.1 Atmospheric degradation (or fate in the atmosphere)
. . . In the atmosphere PAHs are partitioned between the gas and particle phases, with the gas-particle partitioning depending on a number of factors, including the liquid-phase (or sub-cooled liquid-phase) vapour pressure of the PAH at the ambient atmospheric temperature, the surface area of the particles per unit volume of air, and the nature of the particle (Wania & Mackay, 1996; Pankow, 1987; Bidleman, 1988). As a first approximation, chemical compounds with liquid-phase vapour pressure of PL< 10-5 Pa at the ambient atmospheric temperature are present in the particle phase, and those with values of PL> 10-2 Pa at the ambient atmospheric temperature are essentially totally in the gas phase (Arey & Atkinson, 2003). As shown in measurements performed in Norway (Oslo), Germany (Bayreuth) and California USA (Torrance), the 2-4 ring PAHs with vapour pressures ≥ 10-4 Pa are largely gas-phase species, whereas PAHs with 4 rings or more, with vapour pressure < 10-4 Pa are particle-associated (see Table B.4.1).
