Assessment of Contribution of Suspended Particulate Matter (SPM and RSPM) Levels in Ambient Air Pollution

摘要

This study set out with the aim of assessing the importance of elements influences in ambient air and their distribution in the environment. The outdoor air measurements have been carried out during winter to investigate possible effective particulate matter PM exposure of different size aerosol RSPM and SPM (fine and coarse modes).The measurements of elements pollution was taken at Indian Institute of Technology campus in New Delhi that considered being a potential reference site for pollution study. The samples were collected at outdoor on the 3rd floor at 15 meters above the street (latitude 28°32' N and longitude 77° 11' E) for 21 hours duration and the elements of Cr, Mn, Fe, Cu, Ni, Zn, and Pb were measured using atomic absorption spectroscopy analysis.. The results indicate that a ratio of RSPM and SPM fine mode/coarse mode is 52.7%. The element's concentration contribution in the site air pollutant is revealed relatively the anthropogenic distributed in ambient air. The amount of enrichment factors for elements Cr, Fe, Cu, Ni, Zn, and Pb is likely originated from the anthropogenic emission source, while the lower enrichment factor of Mn value (<10) contributed to soil characteristics dispersion.
