“Evaluation of Particulate matter and air pollutants level in the ambient air of Bengaluru city”
Keywords:
Air pollution, particulate matter, nitrogen dioxide, sulfur dioxide, carbon monoxide.Abstract
Introduction:
Air pollution has been a global environmental concern, and its effects on human health in the past have played an important role. Thus, this study investigated the concentrations of particulate matter (PM10, PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO) in four distinct areas of Bengaluru over one year.
Materials and Methods:
The research employed a descriptive cross-sectional design, utilizing secondary data from the Central Pollution Control Board's National Air Quality Monitoring Programme. Gaseous pollutants were sampled every four hours, and particulate matter was sampled every eight hours. The study covers four key areas in Bengaluru – Hebbal, Majestic, Saneguruvahalli, and Silk Board. Data analysis was conducted using SPSS software, expressing descriptive statistics such as mean, standard deviation, and maximum concentrations.
Results:
The findings illustrate varying levels of air quality over the study period. PM10 levels exhibit fluctuations, reaching a peak of 102 µg/m3 in Silk Broad station in August 2023. NO2 concentrations show pronounced spikes, particularly in Silk Broad station in February 2023. SO2 levels display moderate variability, with a peak in Majestic station in March 2023. CO levels, while generally lower, still reach concentrations posing health risks, with a peak in January 2023 in Majestic station. Regional disparities are identified, with the Silk Board station recording the highest PM10 concentration, and the Majestic station exhibiting elevated levels of NO2, SO2, and CO.
Conclusion:
This comprehensive study underscores the critical role of air quality monitoring in assessing environmental health risks. Identified pollutant hotspots necessitate targeted interventions, providing valuable information for evidence-based policymaking. The findings emphasize the urgent need for continuous monitoring and multifaceted interventions to improve air quality, safeguard public health, and contribute to overall well-being in Bengaluru.
