    • Traffic related air pollution with particulate matter, sulfur pollutant and carbon monoxide levels near NH-44 in India


      More Details Abstract Fulltext PDF

      For the past two decades, the quality of air has been deteriorating. It is indeed a great threat to the environment. The primary source of air pollution is vehicular emission in urban areas. Hence air quality monitoring and assessment are required to understand the level of pollution and for its remedial measure. Here,air quality has been measured at three locations (Govardhan Intersection, GLA University and K.D. Hospital) besides National Highway 44, near Mathura City, India. Average weekly concentration of PM2.5, PM10, CO and SO2 were 1231.72 μg/m3, 1860.43 μg/m3, 7.43 mg/m3 and 48.93 μg/m3, respectively near Mathura city. Higher concentrations of PM2.5 and PM10 were obtained due to heavy heterogeneous traffic. The increment in the PM2.5 and PM10 concentration level results in cardio-vascular, cardio-pulmonary and respiratory diseases. These diseases will affect human beings for a long-term syndrome. Technique for order performance by similarity to ideal solution (TOPSIS) method is used to rank the sampling locations based on their pollution level and found that Govardhan Intersection obtained the maximum value in terms of pollutant concentrations on a weekly basis. This research will be helpful in the management of air pollution as Mathura is a high-demand tourism center.
