This paper explores the association between acute respiratory morbidity and different measures of exposure to airborne particulate matter, including sulfates, total suspended particulates, and fine and inhalable particulates. Regression analysis was used to test for the impacts of these alternative measures of particulate matter on respiratory morbidity using the 1979-1981 annual Health Interview Surveys and EPA's Inhalable Particle Monitoring Network. The general results indicate that, of the surrogate measures for particulate matter, sulfates appear to have the greatest association with morbidity. To the extent that sulfuric acid aerosols are correlated with airborne sulfates, the results suggest that respiratory impairment sufficient to lead to days of reduced activity may be related to the existence of acidity in the air. These findings are consistent with the results of ecological studies reporting an association between mortality and exposures to fine particles and sulfates.
本文探讨了急性呼吸道疾病发病率与空气中颗粒物不同暴露指标之间的关联，这些指标包括硫酸盐、总悬浮颗粒物以及细颗粒物和可吸入颗粒物。利用1979 - 1981年年度健康访谈调查和美国环境保护局的可吸入颗粒物监测网络，通过回归分析来检验这些颗粒物替代指标对呼吸道疾病发病率的影响。总体结果表明，在颗粒物的替代指标中，硫酸盐似乎与发病率的关联最大。就硫酸气溶胶与空气中硫酸盐相关的程度而言，结果表明足以导致活动天数减少的呼吸功能损害可能与空气中的酸度有关。这些发现与生态研究结果一致，生态研究报告了死亡率与细颗粒物和硫酸盐暴露之间的关联。
