Pre-monsoon Analysis of Vehicular Pollution on Highly Traffic Loaded Squares of Indore City

RSPM (PM₁₀) Gaseous pollutant like SO_2, NO₂ and Air Quality Index has been simultaneously measured during the pre-monsoon month of April and May 2019 at the busiest squares of Indore city which are Palasia and Palsikar. Sampling was conducted with the help of respirable dust sampler and was followed by CPCB norms. The lowest RSPM has been observed in the morning time at Palsikar square that is 61 µg/m³ and highest in the morning that is 123 µg/m³; similarly, at Palasia square the RSPM concentration in morning detected as lowest was 104 and 127 µg/m³ as highest during the month. At evening peak hours the concentration at Palsikar square have been observed 117 µg/m³ as lowest and 186 µg/m³ as highest. On the other end the concentration at Palasia square has been observed 181 µg/m³ as lowest and 187 µg/m³ as highest. It is observed that the gaseous pollutant concentration was lowest at Palsikar and highest at Palasia and AQI remains moderate except Palasia. This data can help to analyze the present status of vehicular pollution with the respective squares and can also help in the future for making some policies to prevent it.
