Toxicities of PM2.5 Polyaromatics Hydrocarbon on indoor Air Emitted During Fuming of Incense and Mosquito Coil Materials

Author(s): Basant Shubhankar and Balram Ambade

In this work, the concentration and fluxes of particulates polycyclic aromatic hydrocarbons 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 was 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 concentration of PAHs (i.e. Phe, Cor, Fla, Bgh, Baa, Cry, Bbf, Ant, Dba, Ind, Pyr, Bkf and Bap) in PM2.5 emitted during fuming of the IS and MC materials are described. The chemical composition of the PM2.5 is also discussed.
