Objective summary: Pollution issues in India
Gupta and Dhir (2021) conducted a study to investigate the dimensional and chronological differences of air contaminants within agglomeration zones in Gujarat. The study was conducted to address the issue of air pollution, which has become a growing concern in the country due to its negative effects on public health and the environment. The research was conducted in the urban agglomeration areas of four major cities in Gujarat: Ahmedabad, Vadodara, Surat, and Rajkot. The study period spanned 14 years from 2004 to 2018. Gupta and Dhir (2021) utilized a quantitative research methodology. Furthermore, the researchers used geographic information systems (GIS) to create maps showing the spatial variations of air pollutant concentrations in the urban agglomeration areas of the four cities. (Gupta & Dhir, 2021)
The study utilized data from air quality monitoring stations within agglomeration zones of the four cities, which measured the quantity of air contaminants like particulate matter (PM10 and PM2.5), nitrogen oxides (NO2), and sulfur dioxide (SO2). The data was analyzed using statistical tools such as the Mann-Kendall test to evaluate the tendencies in air pollutant concentrations over time. These statistical tools allowed the researchers to identify and quantify any significant temporal changes in the air pollutant concentrations over the study period. The study found that the concentrations of air pollutants varied spatially, with higher concentrations observed in areas with heavy traffic and industrial activities (Gupta & Dhir, 2021). Again, the researchers found that that PM2.5 and PM10 led to more contamination when equated with SO2 and NO2. Additionally, the study found that the quantities of air contaminants were generally higher in the winter period than in the summer period. (Gupta & Dhir, 2021)
