Abstract
This paper presents an observational study on the air quality and horizontal visibility in Raipur city of India. The air quality in Raipur city is deteriorated on account of large number of iron steel industries and increasing vehicular and population pressure. The paper presents interplay between suspended particulate matter (SPM), ultrafine particles (DUST), meteorological parameter and the horizontal visibility in a yearlong study. Observations were carried out a long traffic corridor between Bhilai and Raipur city. Air quality parameters [SPM and DUST] were found to be more important than the meteorological parameter for the visibility reduction in the study area. The visibility at both Raipur and Bhilai location has shown strong negative correlation with the SPM in air which translates into the fact at higher SPM is causing reduction in the visibility. This correlation in case of DUST is not as strong in case of SPM, which proves that SPM by being able to remain suspended in air for longer time plays a greater role in visibility reduction. It is also clear that the air visibility observation can an effective indication of the air quality prevailing in a particular area.
