Abstract : Air will be impure for respiration of man and animals due to emission of pollutants by combustion of household
fuels like wood, kerosene, coal and Cowdung cakes. The common indoor air pollutants are CO, NOX, SOX and particulate
matter (PM10, PM2.5 and PM1.0). The present work is on exposure assessment of particulate pollution in households for two
different fuels i.e., coal and cowdung cakes. The sampling stations were considered randomly in and around Mysuru city.
Indoor concentration of Respirable Suspended Particulate Matter (RSPM) for the fuels were monitored using Personal air
sampler. Sampling before, during and after cooking was carried out for about 2 hours. The average indoor concentrations
before, during and after cooking were found to be 68.65, 1154.9, 372.46 μg/m3 respectively for coal. The average Indoor
concentrations before, during and after cooking was found to be 65.84, 1387.4, 438.27 μg/m3 respectively for Cowdung
cakes. The RSPM concentration in the cowdung cakes fuel household is very high when compared to coal. To characterize
the morphology of RSPM, filter papers were examined using Scanning Electron Microscope. From these SEM images, it can
be observed that particles has a susceptibility to form flocculated aggregates, known as ‘Spherules’ less than 100nm in
equivalent spherical diameter (ESD), where as Individual particles or ‘Spherulites’, are less than 10nm.
