TI  - Suspended particulate matter distribution in rural-industrial Satna and in 
      urban-industrial South Delhi.

AB  - An air quality sampling program was designed and implemented to collect the 
      baseline concentrations of respirable suspended particulates (RSP = PM10), 
      non-respirable suspended particulates (NRSP) and fine suspended particulates (FSP 
      = PM2.5). Over a three-week period, a 24-h average concentrations were calculated 
      from the samples collected at an industrial site in Southern Delhi and compared 
      to datasets collected in Satna by Envirotech Limited, Okhla, Delhi in order to 
      establish the characteristic difference in emission patterns. PM2.5, PM10, and 
      total suspended particulates (TSP) concentrations at Satna were 20.5 +/- 6.0, 
      102.1 +/- 41.1, and 387.6 +/- 222.4 microg m(-3) and at Delhi were 126.7 +/- 
      28.6, 268.6 +/- 39.1, and 687.7 +/- 117.4 microg m(-3). Values at Delhi were well 
      above the standard limit for 24-h PM2.5 United States National Ambient Air 
      Quality Standards (USNAAQS; 65 microg m(-3)), while values at Satna were under 
      the standard limit. Results were compared with various worldwide studies. These 
      comparisons suggest an immediate need for the promulgation of new PM2.5 
      standards. The position of PM10 in Delhi is drastic and needs an immediate 
      attention. PM10 levels at Delhi were also well above the standard limit for 24-h 
      PM10 National Ambient Air Quality Standards (NAAQS; 150 microg m(-3)), while 
      levels at Satna remained under the standard limit. PM2.5/PM10 values were also 
      calculated to determine PM2.5 contribution. At Satna, PM2.5 contribution to PM10 
      was only 20% compared to 47% in Delhi. TSP values at Delhi were well above, while 
      TSP values at Satna were under, the standard limit for 24-h TSP NAAQS (500 microg 
      m(-3)). At Satna, the PM10 contribution to TSP was only 26% compared to 39% in 
      Delhi. The correlation between PM10, PM2.5, and TSP were also calculated in order 
      to gain an insight to their sources. Both in Satna and in Delhi, none of the 
      sources was dominant a varied pattern of emissions was obtained, showing the 
      presence of heterogeneous emission density and that nonrespirable suspended 
      particulate (NRSP) formed the greatest part of the particulate load.
