“…PM10 and PM 2.5 affect the total air ions concentration. It is caused by their common emission sources like vehicular emission, industry, and energy generation (Skromulis, 2019). Skromulis (2019) also reported that relative humidity does not any large or unambiguous impacton AIC directly, while air temperature affects the AIC by increasing it concentration.…”

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.

Evaluation of air quality involves both chemical and physical parameters, however, the importance of the physical ones is often undervalued. A specific integral parameter of the physical state of ambient air is the air ion concentration. Air pollution correlates with air ion concentration. Cluster ions and aerosol ions have the most significant impact on human health. Negative cluster ions are considered to be necessary for human well-being. Previous studies in Rezekne city (Latvia) have highlighted the decrease of positive and especially negative air ion concentrations near the most polluted areas, i.e. the main street junctions and the railway station. Air pollution in Rezekne mainly comes from automotive transport. The aim of this study is to determine the concentration of cluster ions emitted directly from the automobile exhaust pipe. Firstly, the air ion concentration near busy traffic was measured. Secondly, the experiment was carried out using two motor vehicles running on three different types of fuel: gasoline, liquified petroleum gas, and diesel. The portable bipolar light ion counter Sapfir-3M was used in the experiments. The results show that the concentration of air ions in direct exhaust gases can be up to ten times higher than the ambient background concentration. In most cases the experiment revealed the predominance of positive ions over the negative ones, and only in some cases the situation was opposite. It was concluded that only the later chemical and physical processes can lead to decrease of air ion concentration due to pollution. In the article several related circumstances are discussed and proposals on further research are defined.
