A multi-year study of air pollution and respiratory hospital admissions in three New York State metropolitan areas: results for 1988 and 1989 summers.

摘要: As part of a multi-year study air pollution and respiratory hospital admissions in the Buffalo, Albany, New York City, York, metropolitan areas, filter samples were collected daily at suburban monitoring sites analyzed for their content particulate phase aerosol strong acidity (i.e., hydrogen ion, H+) sulfate (SO4 =). In addition, causes, other community pollutant measurements (e.g., ozone, O3), meteorological data temperature) also obtained these areas. The summer months (June-August) selected analysis because that is when highest H+ (and O3) are usually experienced sites, rarely complicated by major influences high pollen counts). Thus, any pollution-admissions relationships expected to be most clearly discernible this season. Prior health effects analysis, environmental first detrended eliminate long-wave autocorrelations, day-of-week removed via regression. Cross-correlations filtered 1988 1989 revealed associations between elevated haze H+, SO4 =, increased total asthma on same day and/or subsequent daysmore » Buffalo especially during (when levels more extreme). Regression analyses indicated remained significant (p < 0.05) even after simultaneous inclusion lagged maximum temperature. Mean calculations cities summertime can play role occurrence season: accounting an average 6 24% NYC admissions. O3 consistently had mean estimates.« less
