Study on Temporal and Spatial Variation of PM2.5 on South Delhi
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
A high pollution level of PM2.5 particles is dangerous and harmful to human health as it causes deep penetration into the lungs. It can reach the alveolar region as well as have the potential to reduce the visibility of environment. A key objective of this work is to understand the patterns of spatial and temporal variability of pollutants, particularly PM2.5. Ten stations have been selected for the monitoring of PM2.5 for 24 hour duration in south Delhi at residential, institutional, commercial and industrial area. Portable Aerosol spectrometer model 1.108 (Real time GRIMM Dust monitor) has been used. The average concentration of PM2.5 is found 109μg/m3 at Jamia Nagar, 115μg/m3 at Jasola, 113μg/m3 at Zakir Nagar, 114μg/m3 at New Friends Colony, 117μg/m3 at Abul Fazal Enclave, 119μg/m3 at Shaheen Bagh, 121μg/m3 at East of Kailash, 124μg/m3 at Nehru Place, 122μg/m3 at Maharani Bagh, 126μg/m3 at Lajpat Nagar. These observed concentrations are significantly higher than National Ambient Air Quality (NAAQ) standards, suggesting poor quality of air at South Delhi which requires action by public authorities at the national, regional and local levels to improve the air quality.
