Relation of fractional exhaled nitric oxide (FENO) to ambient particulate matter (PM2.5) mass, composition and oxidative potential, and to air pollutant gases. The percent change in FENO is in relation to a one-interquartile range change in the concentration of the air pollutant (Table 2), adjusted for personal temperature, personal relative humidity, and exposure run. DTT, dithiothreitol; EC, elemental carbon; OC, organic carbon; ROS, reactive oxygen species; WSOC, water-soluble organic carbon.
