Abstract

The level of air ions considers as an early detection tool for change in the environmental pollutants. The advancement in storage and transportation technology has increased the concentration of air ions in an urban environment. Significant literature reveals that if positive air ions are present in a large number, it has severe health impacts on the human body.
This paper discusses the seasonal scanning of air ions at a traffic junction and green zone. The spot sampling methodology used in this study and assessment of air ions count (AIC) during both summer and winter seasons in 2019 at Nagpur city, India. The study reveals that the critically polluted regions are season invariable concerning air ions as a precursor of pollution. The observation of fewer values in negative ions for both the summer and winter season in traffic intersections grounded the fact that seasonal washout of pollutants is not there, which is observed for green zones. The vehicle counts and its density in the green zone play a critical role in the concentration of negative ions. The air ion ratio (-/+) of the morning, afternoon, and the evening was 1.030, 1.142, and 1.142, respectively in the green zone and having lowest values in the traffic location (morning, afternoon, and the evening was 0.92, 0.83, and 0.77, respectively). The increment or decrement in the ion ratio could help understand the prevailing air quality scenario in the urban macro-environment.
