SPM levels of an urban area (Patiala City) and its relation to automobile exhaust

Original Paper

Abstract

Concentration levels of suspended particulate matter (SPM), organic tarry matter (BSPM), ignitable matter (LOI) and lead in the ambient air of an urban area are measured by using a high volume sampler. SPM levels in different zones of the city are reported. Organic tarry matter measured as benzene soluble particulate matter (BSPM) constitutes about 4–9% of the SPM. BSPM in the ambient air varies in a range of 10–40 μg m−3. Ignitable matter measured as loss on ignition (LOI) forms about 24–40% of the SPM. Absolute values of LOI vary between 50 and 150 μg m−3. Concentrations of BSPM, LOI and Pb are correlated to automobile exhaust as the probable source.

The studies indicate that BSPM and LOI are integral parts of the SPM but their concentrations are independent of the SPM levels.
