ABSTRACT
Large solid and liquid particles (typically greater than 10 µm in aerodynamic diameter) are collected via gravitational settling in an open-mouth container for a designated period of time. The container is washed with a known amount of distilled water, which is filtered and then evaporated. The mass of insoluble particles is determined by the weight-gain of the filter after filtration. The mass of soluble particles is determined by the weight gain of a crucible after evaporation. These weight gains are translated into insoluble, soluble, and total particle deposition fluxes by normalizing the mass measurements by the collection area of the container and the sampling time (1,2,3).
