^aReported betas are scaled to two standard deviations of the deviated predictors across all eight communities as follows: 1.6 units for logged freeway CALINE4, 1.1 units for logged total CALINE4, 84.5 meters for elevation, 1574 individuals/km² for population, 5260 meters for distance to shoreline, 0.1 for NDVI, 6250 trucks for freeway truck count, and 4300 meters for distance to intermodal facility.

^bA stable model could not be fit for Mira Loma (ML), which was likely attributable to the small number of samples available for this analysis.
