Abstract: | Development of an effective agricultural crop residue management plan in the Northwest region of India has been hindered by the lack of awareness and information about the adverse impact of agricultural residue burning practices on regional ambient air quality. These practices emit SPM and gaseous species into the atmosphere influencing health and materials in the area. Open wheat (Triticum aestivum) and rice (Oriza sativa) crop stubble burning events are observed in and around Patiala city during April-May and October-November every year. A study involving ground level measurements was conducted to analyze the contribution of wheat and rice crop stubble burning practices on concentration levels of suspended particulate matter (SPM), Oxides of sulphur and nitrogen (SO2 and NO2) were monitored in the ambient air at five different sites in and around Patiala city covering agricultural, commercial and residential areas. Aerosol samples were collected on GMF/A and QMF/A (Whatman) sheets using High Volume Sampling (HVS) units for a 24 h period throughout the study period covering four rice and three wheat crop harvesting seasons from 2006-2010. Simultaneously, sampling of SO2 and NO2 was conducted and results obtained during stubble burning periods were compared with the non-stubble burning periods. Interesting results were obtained during this course of study. Results pointed out a distinct increase in aerosol, SO2 and NO2 levels during the crop stubble burning periods. Further, SPM samples were analyzed for the determination of organic tarry matter (OTM), loss on ignition (LOI), heavy metals and poly aromatic hydrocarbons (PAHs). Results indicated a clear impact of crop residue burning practices in Northern India. Average levels of LOI pointed to the presence of a high content of combustible matter in the ambient air of Patiala. It has been observed that levels of combustible matter content were associated with the levels of SPM integrated with the effect of crop residue burning (CRB) practices in the region. |
