Objective:
Recent findings of the association between daily mortality and ambient daily PM10 and PM2.5 concentrations well below the 24-h National Ambient Air Quality Standards (NAAQS) for PM10 has prompted the new NAAQS for PM2.5. However, whether the population exposure to PM is related to the concentration measured at an outdoor site remains unanswered. This study was funded to provide information to resolve this crucial issue. The study subjects are patients with chronic respiratory disease and cardiovascular complications residing in the metropolitan Seattle area. Year-round personal, biological, indoor, and outdoor PM measurements, as well as other co-varying air pollutants will be taken from 60 patients. The objectives of this study are to: (1) determine the strength of the relationship of the particle exposures of high-risk subpopulations to the concentrations measured by a central monitoring station; (2) characterize the key factors influencing this relationship; and (3) link exposure data with health outcomes to focus exposure modeling on unbiased estimation of health effects. This study is being conducted in the Seattle Metropolitan area. Personal, biological (urine and breath), indoor, and outdoor PM10, PM2.5, CO, SO2, and NO2 measurements are taken throughout the year using the Harvard/Marple personal exposure monitors for PM, passive monitors for CO, SO2, and NO2, and nephelometers for continuous PM1. The biomarker technique recently developed at the University of Washington serves as a unique tracer for ambient PM exposures. At any given time, 5 patients are monitored simultaneously and 30 patients are to be monitored in high and medium-low wood smoke seasons each year. Subjects include 30 chronic obstructive pulmonary disease (COPD) and 30 cardiovascular patients living in either group or private homes, as well as 24 healthy subjects monitored as controls. We also collect information on personal time-location-activity-symptom, events that occur in residences that may generate or reduce PM, building characteristics, continuous CO2 concentrations, temperature, and relative humidity. Furthermore, the exposure data are supplemented with peak expiratory flow rate, pulse rate, oxygen saturation, blood pressure, and electrocardiogram measurements from all subjects.Publications and Presentations:
