Long-term exposure to auto exhaust and other pollutant mixtures

Research report:beagles were exposed 16 hr daily for 61 months to raw and photochemically reacted auto exhaust, nitrogen oxides, and sulfur, alone and in combination. exposure to nitrogen oxides reduced diffusion capacity and peak expiratory flow. raw exhaust and raw exhaust plus sulfur oxides produced pulmonary hyperinflation. irradiated auto exhaust also impaired ventilatory distribution. lung volumes, compliances, and maximal breathing capacity were not impaired by the experimental atmospheres. such chronic pulmonary changes resulting from long-term, low-level exposure to ubiquitous urban air pollutants denote potential, serious health hazards.
