24-hour average time-series plots for PM2.5 concentrations (μg/m3) recorded in the personal, kitchen, living room, and community monitors by season and primary cooking fuel combinations. There were 123 (13,761 person-hour), 167 (18,663 person-hour) and 94 (10,607 person-hour) subjects for the “Solid fuels included”, “Clean fuels” and “No cooking” group in summer, respectively; There were 126 (13,174 person-hour), 173 (17,956 person-hour) and 65 (6819 person-hour) subjects for the “Solid fuels included”, “Clean fuels” and “No cooking” group in winter, respectively. Smaller plots nested within panels are “zoom-in” version of the corresponding plot, as the use of a universal y-axis limit up to 1200 with reference to the kitchen exposure levels impaired the readability of those plots.
