Acute respiratory symptoms in patients with chronic obstructive pulmonary disease and in other subjects living near a coal-fired plant
Daily symptom rates in patients with chronic obstructive pulmonary disease and in other subjects with presumed high sensitivity to air pollution who lived near a coal-fired power plant were compared with 24 h ambient air concentrations of NO/SUB/2, SO/SUB/2, soot and suspended particles, as well as with emissions from the plant. The mean concentrations of each of the pollutants during the 4-month study period were below 30GAMMA/m/SUP/3, and no single 24h concentration exceeded 100GAMMA/m/SUP/3. There were no consistent associations between plant emissions and pollutant levels, or between these two variables and daily symptom rates. The results indicate that the coal-fired plant was not of major importance for the occurrence of acute respiratory symptoms in the surrounding population.
