1 ABSTRACT Chapter II describes results from 197 rural households that were sampled over five continuous days for indoor and outdoor PM 10 , PM 2.5 , and endotoxin. Geometric mean indoor concentrations of PM 10 and PM 2.5 (21.2 µg m-3 , 12.2 µg m-3) were larger than outdoor concentrations (19.6 µg m-3 , 8.2 µg m-3 ; p =0.072, p<0.001), while geometric mean… (More)
