Title

Study of Seasonal and Spatial Variability among Benzene, Toluene, and p-Xylene (BTp-X) in Ambient Air of Delhi, India

Pages

  135-146

Abstract

 This study was carried out to analyze the variations of Benzene, Toluene, and para-Xylene (BTp-X) present in the Urban Air of Delhi. These pollutants can enter into the human body through various pathways like inhalation, oral and dermal exposure posing adverse effects on human health. Keeping in view of the above facts, six different locations of Delhi were selected for the study during summer and winter seasons (2016-2017). The concentrations of BTp-X on online continuous monitoring system were analyzed by chromatographic separation in the gaseous phase followed by their detection using a Photo Ionization Detector (PID). The concentrations of BTp-X were found maximum at a high traffic intersection area as 68. 35± 48. 26 μ g/m3 and 86. 84± 32. 55 μ g/m3 in summer and winter seasons respectively and minimum at a residential area as 4. 34± 2. 48 μ g/m3 and 15. 42± 9. 8 μ g/m3 in summer and winter seasons respectively. The average BTp-X concentrations of summer and winter seasons were found as 9. 88, 20. 68, 28. 52, 49. 75, 64. 04, and 77. 59 μ g/m3 at residential, institutional, commercial, low traffic intersection, moderate traffic intersection and high traffic intersection areas respectively. Clearly, it has been found that the concentrations of these compounds were more on the traffic areas indicating that the Vehicles are the major emission source. Hence, it may be concluded that the number of Vehicles along with the high traffic congestion on the city streets and roads results in more accumulation of aromatic compounds and deteriorate the Urban Air quality.
