Indoor air quality in areas of different exposure: an experimental study

Abstract

The present study focuses on experimental study of indoor air quality regarding PM10, PM2.5, CO,
CO2, NO, NO2, SO2 in selected differently used areas. Cooking places (kitchen) at different
locations using different types of cooking fuel used and living room were selected for the purpose
of the measurements. For the purpose of pollutant monitoring 20 households for each having
different types of kitchen using biomass fuels and LPG were selected. The indoor air quality of the
living room of those households was also assessed for the purpose of comparison. The indoor
environment was measured with handy portable samplers. Experimental results obtained shows
that the indoor air quality of households cooking with biomass fuels is worse while the indoor air
quality of the households using LPG was also found to be much above the prescribed guidelines
especially in multipurpose room and in non-ventilated kitchen and on the other hand the indoor
air quality of living room is little better but affected by kitchen emissions.
