During biomass burning, linear regression showed a decreasing trend of geometric mean PM 2.5 and CO concentrations from the biomass stove (326.3 μg/m 3 , 12.3 ppm), to index home (322.7 μg/m 3 , 11.2 ppm), neighbor homes sharing a wall with the index home (278.4 μg/m 3 , 3.6 ppm), outdoors (154.2 μg/m 3 , 0.7 ppm), then neighbor homes that do not share a wall with the index home (83.1 μg/m 3 ,0.2 ppm) ( p = 0.03 for PM 2.5 , p = 0.006 for CO).
