Determination of outdoor (ambient) and indoor air quality status in the rural residential adjoining jhansi city

Utilization of fuel-wood as a source of energy is a major source of indoor air pollution in the study area. Two villages nearby Jhansi City have been selected for the study purpose. Indoor and outdoor air quality in both rural residential areas has been monitored in winter, summer and monsoon seasons. In has been observed in the study that at all the selected sites, the average concentrations of the SPM and RSPM are high in winter in comparison to the summer and monsoon season. It was also noticed that SPM level at outdoor sampling sites in winter and summer the exceeds the prescribed limits as stipulated by central pollution control board (CPCB) New Delhi. The average concentration of SO2 and NOx were found below the permissible limits of CPCB at all the sites but NOx concentration was higher than the outdoor NOx concentration. SPM and RSPM were monitored through gravimetric method. West and Gaeke method was used for analysis of SO2 (West and Gaeke, 1956) and Jackob and Hochheiser (1958) modified method for analysis of NOx. From the entire study it has been found that maximum families especially in rural area having improper ventilation and used of solid biomass.
