An air pollution study was conducted in Nashville, Tennesses in 1958-1959. The study was conducted to investigate possible relationships between air pollution and health and to obtain information on a number of the engineering and meteorologic phases of air pollution. As one aspect of the study, sulfur dioxide was studied intensely, from a detailed emission inventory to ambient air measurements using several sampling techniques. This paper discusses sulfur dioxide source strength and ambient levels of sulfur dioxide reported in terms of sulfation, using lead peroxide candles, as a function of radial distance from the center of Nashville.
