Abstract

The chemical composition of particulates in subway air collected during nonheating and heating seasons were determined by infrared analysis. The inorganic constituents were found to include sulfate, nitrate, bromate and silica. The principle sulfate compounds were ferrous sulfate and zinc sulfate. The infrared spectra also indicate the presence of an α, β unsaturated aldehyde such as acrolein. Some variation of composition with particle size was found. The possible presence of (NH₄)₂SeO₄was also observed, but only during the heating season. The principle sources of the pollutants appear to be emissions from automobiles, power plants, incineration, and braking operations and track-wheel abrasion of the subway cars.
