This study was undertaken to determine the effects in primates of chronic inhalation exposure to nitrogen dioxide, sulfur dioxide, carbon monoxide, lead chlorobromide, and calcium sulfate, alone and in binary combinations. Juvenile male and female cynamolgus monkeys (Macaca irus) were randomized into 20 groups of 9 monkeys each. Only monkeys exhibiting normal pulmonary function and normal hematological and clinical biochemical values were selected for study. One group of monkeys served as a control and was exposed to filtered room air. The remaining 19 groups were exposed to the various pollutants or pollutant combinations for 22 hr/day, 7 days a week
