“…However, the monotonically decreasing mass fractions associated with coarse particles from naphthalene to benzo(g,h,i) perylene (Fig. 2) with decreasing sub-cooled liquid vapor pressure (P L , Pa; 298 K) (Lei et al, 2002;Sonnefeld et al, 1983) suggested a volatility dependency for the particle size distribution. On the other hand, the size distributions of all target PAHs except for naphthalene, acenaphthylene, acenaphthene, and fluorene were unimodal, peaking in the 1.0-1.8 μm fraction (Supplementary material, Figs.…”

initiated a programme on the evaluation of the carcinogenic risk of chemicals to humans involving the production of critically evaluated monographs on individual chemicals. The programme was subsequently expanded to include evaluations of carcinogenic risks associated with exposures to complex mixtures, life-style factors and biological and physical agents, as well as those in specific occupations. The objective of the programme is to elaborate and publish in the form of monographs critical reviews of data on carcinogenicity for agents to which humans are known to be exposed and on specific exposure situations; to evaluate these data in terms of human risk with the help of international working groups of experts in chemical carcinogenesis Publications of the World Health Organization enjoy copyright protection in accordance with the provisions of Protocol 2 of the Universal Copyright Convention.

IARC Library Cataloguing in Publication Data NOTE TO THE READERThe term 'carcinogenic risk' in the IARC Monographs series is taken to mean that an agent is capable of causing cancer under some circumstances. The Monographs evaluate cancer hazards, despite the historical presence of the word 'risks' in the title.Inclusion of an agent in the Monographs does not imply that it is a carcinogen, only that the published data have been examined. Equally, the fact that an agent has not yet been evaluated in a Monograph does not mean that it is not carcinogenic.The evaluations of carcinogenic risk are made by international working groups of independent scientists and are qualitative in nature. No recommendation is given for regulation or legislation.Anyone who is aware of published data that may alter the evaluation of the carcinogenic risk of an agent to humans is encouraged to make this information available to the Section of IARC Monographs, International Agency for...

Absorption of Semi-Volatile Compounds in Oiled Impaction Substrates: Measurement of Pyrene Absorption

ABSTRACT. Oiled impaction substrates have been used to prevent particle bounce during the collection of size-segregated aerosol samples, which have been analyzed for trace-level airborne organic compounds, including polycyclic aromatic hydrocarbons (PAHs). The use of the oiled impaction substrates, however, may introduce another sampling artifact-the absorption of semivolatile species from the gas phase which could arti cially increase the amount of PAHs attributed to the aerosol. In this article, laboratory measurements of the absorption of a particular PAH, pyrene, from the gas phase to impaction substrates of polytetra uoroethylene membranes impregnated with dibutyl phthalate are reported. Overall mass transfer coef cients are determined from the data. These results are used to calculate the absorption of gas phase PAHs during sampling of size-segregated atmospheric particles. Criteria are developed to determine if the absorption artifact is negligible. The rst criterion requires that the analyte be negligibly soluble in the oil; this criterion is met by none of the impaction oils reported in the literature. The second criterion is that species do not have time to reach an equilibrium distribution between the gas phase and impaction oil; this criterion is met for nonvolatile species, those with vapor pressures equal to or less than that of benzo[a]pyrene (3.5 3 10 6 Pa). We recommend that oiled impaction substrates be used only if the absorption artifact is expected to be negligible on the basis of these criteria.
