Analysis of Trends in Air Ambient Quality Index: A Case Study of Guwahati City of Assam, India

The daily air pollution levels are crucial, especially for those people who are suffering from some air borne diseases. The air quality index (AQI) values may increase due to increased emissions from vehicles, construction activities, flyovers, road widening, traffic discharge, and lack of rain. Monitoring these factors is essential for maintaining a healthy environment. The study was conducted w.r.t. some major gaseous air pollutants like CO, SO2, NO2, O3, and NH3 along with some fine particulate matter such as PM10 and PM2.5 covered under AQI worldwide. This paper analyzes the AQI data in Guwahati City, Assam, India, aiming to raise public awareness about potential health issues and suggest effective measures for controlling the deteriorating air quality and promoting swift action against air pollution. The investigation revealed a slight increase in aggregate levels of five pollutants, resulting in poor overall AQI levels during the winter session. The study suggests that the increase in AQI value in Guwahati, Assam, India, may be due to construction, flyovers, road widening, and excessive traffic, leading to low visibility and suggests government intervention through smart policies and regular monitoring. The study could be expanded to other districts and regions, conducted cross-nationally for more tangible results, and seasonal variations may be increased for better results.
