Characteristics of indoor air pollutants and estimation of their exposure dose

Rural areas of developing countries have various indoor air pollution sources along with solid fuels used for cooking. This study aims to compare five sources, viz., incense stick, dhoop, mosquito coil, cigarette, and cooking fuel charcoal, respect their potential. The monitoring PM, CO, CO2, NO2, particulate bound heavy metals was carried out. Dhoop (DH1) found be emitting the highest concentration metal Sb among all analyzed metals. Dhoop, sticks, charcoal were having high first-order decay rate equation indicated that constant per hour observed dhoop PM10 PM2.5 coil (M1) CO. half-life cigarette (CG1) (C1) respectively indicating slow in air. average daily dose values age group 6 < 11 years, 16 31 51 years will more vulnerable PM emissions from stick (IS1). hazard index estimated (IS1) charcoal.
