Prediction of activity coefficients in liquid aerosol particles containing organic compounds, dissolved inorganic salts, and water—Part 2: Consideration of phase separation effects by an X-UNIFAC model

Autor: James F. Pankow, Elsa I. Chang

Publikováno v: Atmospheric Environment. 40:6422-6436

A thermodynamic model is presented for predicting the formation of particulate matter (PM) within an aerosol that contains organic compounds, inorganic salts, and water. Neutral components are allowed to partition from the gas phase to the PM, with t

Prediction of activity coefficients in liquid aerosol particles containing organic compounds, dissolved inorganic salts, and water—Part 3: Organic compounds, water, and ionic constituents by consideration of short-, mid-, and long-range effects using X-UNIFAC.3

Autor: James F. Pankow, Elsa I. Chang, John H. Seinfeld, Garnet B. Erdakos

Publikováno v: Atmospheric Environment. 40:6437-6452

X-UNIFAC.3, a group contribution method for estimating activity coefficients of neutral and ionic components in liquid mixtures of organic compounds, inorganic salts, and water, is presented here. It is an extended UNIFAC method, in that traditional

Variation in the sensitivity of predicted levels of atmospheric organic particulate matter (OPM)

Autor: Elsa I. Chang, James F. Pankow

Publikováno v: Environmental sciencetechnology. 42(19)

This study examines the sensitivity in predicted levels of atmospheric organic particulate matter (M(o), microg m(-3)) to changes in the governing gas/particle partitioning constants and the tau(I) (levels of condensable organic compounds, microg m(-

Characterization of measured menthol in 48 U.S. cigarette sub-brands

Autor: Gregory N. Connolly, James F. Pankow, Carolyn Celebucki, Geoffrey Ferris Wayne, Elsa I. Chang

Publikováno v: Nicotinetobacco research : official journal of the Society for Research on Nicotine and Tobacco. 7(4)

More than 25% of cigarettes sold in the United States are branded as mentholated, and these cigarettes are smoked disproportionately among populations with disparate tobacco-related health outcomes. This study is the first (independent of the tobacco
