  • estimating fine particulates less than 2 5 microns in Aerodynamic Diameter pm2 5 from airport visibility data in california
    Journal of Exposure Science and Environmental Epidemiology, 1995
    Co-Authors: David E Abbey, B E Ostro, G Fraser, T Vancuren, Raoul J Burchette
    Abstract:

    Methods were developed for estimating fine particulates less than 2.5 microns in Aerodynamic Diameter (PM2.5) from airport visibility data which detected seasonality and allowed for possible site- and season-specific regressions of PM2.5 on visibility. The methods were applied to nine airports in California in order to produce estimates of PM2.5 for the years 1966-1986 based on 1,767 paired PM2.5/visibility data points where PM2.5 had been measured at a monitoring station near the airport. General F-tests indicated that site- and season-specific regression equations resulted in a statistically significant reduction in residual error. The split halves correlation for estimating PM2.5 from visibility over all areas was 0.82. The methods were used to estimate long-term concentrations of ambient PM2.5 for an epidemiological cohort of 1,868 individuals.

  • chronic respiratory symptoms associated with estimated long term ambient concentrations of fine particulates less than 2 5 microns in Aerodynamic Diameter pm2 5 and other air pollutants
    Journal of Exposure Science and Environmental Epidemiology, 1995
    Co-Authors: David E Abbey, B E Ostro, Floyd Petersen, Raoul J Burchette
    Abstract:

    Seventh-Day Adventists (SDAs), nonsmokers who had resided since 1966 in the vicinity of nine airports throughout California (n = 1,868), completed a standardized respiratory symptoms questionnaire in 1977 and again in 1987. For each participant, cumulative ambient concentrations of fine particulates less than 2.5 microns (microns) in Aerodynamic Diameter (PM2.5) were estimated from airport visibility data. Long-term ambient concentrations of estimated PM2.5 in excess of 20 micrograms per cubic meter (micrograms/m3) were found to be associated with development of definite symptoms of chronic bronchitis between 1977 and 1987. Estimated mean concentrations of PM2.5 were associated with increasing severity of respiratory symptoms related to general airway obstructive disease, chronic bronchitis, and asthma. It was felt that the observed relationships, with the exception of the relationship between increasing severity of chronic bronchitis symptoms and PM2.5, could be due to surrogate relationships with other ambient pollutants.
