Ozone build-up: Delhi-NCR and other metropolitan areas of India confront new air quality crisis
Each year during winter, Delhi-NCR hits the headl that surpasses all permissible limits. However, the concern. According to an analysis by the Centre for (CSE), ground-level ozone increased in 10 metrop summer, with Delhi being the most affected, as rep further highlighted that Delhi-NCR recorded 176 d study period, followed by Mumbai and Pune with 1 According to CSE, it is common for ground-level oz during summer in some locations in Delhi-NCR. However, this year, the number of station across core NCR reached 17.6, the highest in the last five years. Previously, only 9.4 station on average. This number gradually increased, reaching 14.6 stations with exceeded limits The report notes that ideally, ground-level ozone should be negligible at night. However, it a surge in ozone levels after sunset in all 10 metropolitan areas Why is ground-level ozone considered dangerous? According to the report, ground-level ozone is a highly reactive gas that can create serious respiratory conditions, asthma, chronic obstructive pulmonary disease, children with de adults are at serious risk. The gas can inflame and damage airways, make lungs susceptibl asthma, emphysema, and chronic bronchitis, and increase the frequency of asthma attack Roychowdhury, Executive Director of Research and Advocacy at CSE. Another concern is that even in Delhi’s green neighborhoods, high levels of ground-level o areas like Dr Karni Singh Shooting Range and Lodhi Colony. “This is consistent with the s gathers in areas with relatively lower amounts of gaseous pollutants. Thus, relatively clea peripheries, can have comparatively higher ozone concentrations,” added Roychowdhury Avikal Somvanshi, Programme Manager at Urban Lab, CSE, who led the study, said, “Even exceedance is typically worse during summer months, data from the 10 metropolitan area that it is a year-round problem.” 8/7/24, 3:30 PM Ozone build-up: Delhi-NCR and other metropolitan areas of India confront new air quality crisis - CSE asserted that the country should develop a robust public information and dissemin wherever ozone build-up occurs
