Abstract
To determine the long-term effects of air pollutants on adolescents, 42 high school students from an urban industrialized area (Barberton, Ohio) were compared with 50 from a rural area (Revere, Ohio). The comparative measures were vital capacity (VC), forced expiratory volume (FEV1.0), maximal midexpiratory flow (MMF), and maximal indirect oxygen consumption ([Vdot]o2 max). The subjects were all males and were drawn from original populations that were studied three years ago with VC and FEV0.75 being the tests of pulmonary function used.
The results of this study were similar to those of the first. The Barberton group had a mean VC that was lower than the mean of the Revere group (P < .01). Neither FEV1.0 nor MMF were significantly different but [vdot]o2 max was P < .01). Since values for air pollutants are consistantly higher in Barberton, it is concluded that such pollutants should be considered important contributory factors in the impairment of cardiopulmonary functions.
