在辛辛那提、查塔努加和纽约，通过在学校测量三分之一秒用力呼气量（FEV0.75）来评价居住在空气污染程度高和低的社区的小学生的排便能力。5至13岁儿童的排便功能受损与接触颗粒物和硫氧化物之间存在一致的关系。在辛辛那提的研究中，污染社区的儿童在低污染季节的表现有所改善，但没有达到低污染社区的水平。在纽约，对9至13岁儿童的研究结果表明，早期暴露于高空气污染水平5至10年，伴随着排便功能的长期下降。在查塔努加发现了对肺功能的不一致和几乎不显着的影响，在研究之前，那里的二氧化氮高暴露只发生了两到三年。
The ventilatory performance of elementary schoolchildren living in neighborhoods of high and low air pollution in Cincinnati, Chattanooga, and New York was evaluated by in-school measurements of three-quar- ter second forced expiratory volume (FEV0.75). A consistent relationship between impaired ventilatory function in children 5 to 13 years of age and exposure to particulates plus sulfur oxide was demonstrated. In the Cincinnati study, performance of children in polluted neighborhoods improved during seasons of low pollution but not to the level of their counterparts in low exposure neighborhoods. In New York, results in children age 9 to 13 years indicate that early exposure for five to ten years to elevated air pollution levels was accompanied by a prolonged decrement in ventilatory function. Inconsistent and barely significant effects on lung function were found in Chattanooga where high exposures to nitrogen dioxide had occurred for only two to three years prior to the study.
