Popis:	Saint John is the site of an ongoing study of the relationship between cardiorespiratory emergency department visits and airborne particles, including particulate acid and sulfate. The purpose of the present study was to assess the extent to which fixed site monitors reflect average personal exposure to fine particle sulfate and acidity among adults visiting the emergency department with cardiorespiratory disease. Study participants had made an emergency department visit for cardiorespiratory disease in the previous 12 months and resided within approximately 5 km of the fixed site monitor which records the highest sulfate and acid concentrations in Saint John. Twenty-one volunteers wore personal annular denuders during the period from 7 a.m. to 6 p.m. (mean duration 7.6 hours) for up to four separate days between July 6 and August 11, 1995, and completed a time-activity diary for each sampling period. Subjects ranging from 49 to 85 years of age completed a total of 62 sampling periods. The mean p...
