"Phthalates are a class of SVOCs that are widely used as plasticizers and recently epidemiological and toxicological research has found a link between phthalate exposure and increased occurrences of adverse health effects. SVOCs can potentially partition into household dust and airborne particles. Models and micro chamber studies have identified that airborne particles effectively increase SVOC deposition to or emissions from surfaces; SVOCs partition to aerosols in the bulk air, the aerosols then migrate to the surfaces due to eddy and Brownian motion, and then the SVOCs is released inside the SVOC concentration boundary layer adjacent to the surface. Concentration boundary …

The relation between dry diameter (X0) and critical supersaturation (Sc) for atmospheric submicron aerosol particles is investigated using a long term air sampling program at Rolla, Missouri. The particles are passed through an electrostatic aerosol size classifier, and then through an isothermal haze chamber. Results are reported in terms of an apparent volume fraction of soluble material, εv defined such that for particles composed only of ammonium sulfate and water insoluble compounds, εv is the actual volume fraction of soluble material. The probability distribution of εv is found to be approximately Gaussian in …
