For increases in air pollutant concentrations, the authors selected 1 mg/m3 as a standard increase in pollutant concentration for carbon monoxide and 10 μg/m3 for other air pollutants when calculating relative risks.1 However, the studies used 0.9 mg/L, 0.1 mg/m3, and 0.23 mg/m3 for carbon monoxide and 7.5 μg/m3, 10 μg/m3, and 9.1 μg/m3 for particulate matter with an aerodynamic diameter of 10 μm (PM10).2- 4
