Table 2 Association between Near-roadway and Regional Ambient Air Pollution Exposures and Adipokines in Blood and in Tissue. Results were scaled to an interquartile increase in PM2.5 (2.2 μg/m3), PM10 (3.5 μg/m3), NO2 (4.8 ppb), O3 (9.3 ppb), freeway NRAP (3.8 ppb NOx), non-freeway NRAP (1.1 ppb NOx), and total NRAP (4.8 ppb NOx)
