Spatial and temporal real-time ambient Carbon Monoxide ward–wise mapping for BENGALURU City

Abstract

Longevity in life span of city dwellers depends upon the quality of ambient air, which is often compromised due to urbanization. In this context, since independence, Bengaluru has rampantly grown with elevated air and automobile pollution levels. Ambient Carbon Monoxide [CO], which is considered to be the most dangerous criteria air pollutant, however has insufficient research/literature for the city of Bengaluru. To plug this gap, the pre-sent study engages a detailed examination for Temporal and Spatial Map-ping variation of Ambient ‘CO’ concentration in different wards of Bengaluru using calibrated Digital ‘CO’ sensor. The methodology involved primarily an intensive literature review followed by reconnaissance survey for fixation of monitoring stations about each ‘ward’. Further at these observatories, extensive primary data collection was ensued at periodic and regular intervals. The objective serves to delineate the most critical and non-critical places in Bengaluru to incorporate remedial measures. Startling 400+ violations with potential of triggering congestive heart failure, impaired performance in time discrimination, shortened time to angina response and vigilance decrement were observed. Sustainability measures conclude the study.
