Seasonal trends of PM10, PM5.0, PM2.5 & PM1.0 in indoor and outdoor environments of residential homes located in North-Central India
Abstract This study presents data on the size characterization concentration of PM10, PM5.0, PM2.5 and PM1.0. These particulate concentrations were monitored from October-07 to March-09 indoors and outdoors of five roadside and five urban homes using Grimm aerosol spectrometer in Agra, India. Annual average concentrations of coarse particles (PM10) indoor and outdoor were 247μgm−3 and 255μgm−3 at roadside houses and 181μgm−3 and 195μgm−3 at urban houses. PM5.0 concentrations at roadside houses were 211μgm−3 and 230μgm−3 and at urban houses were 145μgm−3 and 159μgm−3. For fine particles (PM2.5) the annual mean concentrations were 161μgm−3 and 160μgm−3 at roadside houses and 109μgm−3 and 123μgm−3 at urban houses. PM1.0 concentrations at roadside houses were 111μgm−3 and 112μgm−3 while at urban houses they were 99μgm−3 and 104μgm−3. Monthly and seasonal variations of coarse and fine particulate matter have been studied at both the monitoring sites. Significant seasonal variations of particulate pollutants were obtained using the daily average particulate concentrations along with the inter particulate ratios. Particulate indoor/outdoor ratios and concentrations were also linked with meteorological conditions and indoor activities using occupant’s diary entries. The concentration of all sizes of particulate matter was found to be highest in winter season due to increase human activities and more space heating in indoors and due to low windspeed and high humidity in outdoors in comparison with other seasons. There was a strong correlation between indoor and outdoor particulate at both the sites. Health problems in occupants of the houses with higher concentrations of the fine particulate matter were more prominent. Household activities like cooking on stoves, indoor smoking and outdoor vehicular traffic, and garbage burning were found to be the major sources of particulate emissions indoor as well as outdoors.
Highlights ► Trends of coarse and fine particulate matter in residential homes of India. ► Monthly and seasonal variations of indoor and outdoor particulate concentrations. ► Particulate indoor/outdoor ratios and its linkage to meteorological conditions. ► Particulate sources and related health effects.
