Ambient Air Quality of Nashik City 2017 (Maharashtra, India)

Ambient air quality of Nasik city was monitored during the year 2017. Criteria pollutants selected for the monitoring was, sulphur dioxide (SO2) & nitrogen dioxide (NO2) and PM10 (Particulate Matter having aerodynamic diameter less than or equal to 10 µm) for the period of January 2017 to December 2017. Sampling was done for successive periods of about 4 hours for sulphur dioxides (SO2), nitrogen dioxide (NO2) and 8 hours for Respirable suspended particulate matter (PM10) for 24 hours. For Air Quality Monitoring, four representative sites were selected i.e. Industrial-S1-I-VIP, Commercial- S2-R-RTO and Residential-S3-C-NMC and Industrial-S4-I-UB. High volume air sampler were used to measure the concentration of nitrogen dioxide (NO2), sulphur dioxides (SO2) and Respirable suspended particulate matter (PM10). The results reported pertain to an eight hour successive continuous air sampling exercise carried out at each of the four selected locations in Nasik city. The value of PM10 (Particles ≥ 10µ, PM 10µg/m3)  was  noted  to  be  crossing  the  permissible   limit   and  exceeded  the  National Ambient Air Quality Standard (NAAQS) at all locations. The concentration of SO2 and NO2 was within the National Ambient Air Quality Standard (NAAQS, National Ambient Air Quality Standers, November 18, 2009) at all the locations.
