Abstract
In this work, the concentration and fluxes of particulates and carbons emitted during fuming of incense (IS) and mosquito coil (MC) materials are described. The concentration of PM2.5 in the indoor environments during fuming of IS and MC (n = 10 each) materials was ranged from 1374 7645 and 260 677 μg/m3 with mean value of 4054±3233 and 392.70±210 μg/m3, respectively. Whereas, the concentration of PM10 ranged from 1465 8597 and 384 784 μg/m3 with mean value of 4296 ± 3284 and 522.4 ± 209 μg/m3, respectively. The mean PM2.5/PM10 ratio for IS and MC materials was found to be 0.94±0.02 and 0.75±0.01, respectively. The concentration of PM2.5 and PM10 was almost same; therefore the detailed investigation of the PM2.5 was carried out. The mean concentration (n = 10) of black carbon (BC) and organic carbon (OC) in the fine mode with IS materials was 733±327 and 2209±1949 μg/m3, respectively. The mean BC and OC concentration with MC materials was 107±11 and 215±55 μg/m3, respectively. Relatively higher concentration (7-9 folds) of the BC and OC was observed with the IS particulates.
