This study investigates the air pollution-induced mortality rate during the second wave of COVID-19, which claimed several thousand lives in the capital city of India, New Delhi, even during a lockdown period. Delhi is a hotspot of unhealthy air quality. During the second wave of COVID-19 in 2021, surface ozone levels were observed to be higher, which had a direct impact on lung function, thereby making people more susceptible to COVID-19. The correlation coefficient between surface ozone concentration and mortality has been observed to be 0.74 at a 95% confidence level. This work focuses on the plausible impact and feedback of poor air quality induced by the burning of open-air funeral pyres due to the increased COVID-19 mortality rate in New Delhi, estimated by using an epidemiological model (AirQ+) of the World Health Organization. The mortality rate estimated quantitatively with the aid of AirQ+ is 1.27 excess deaths per 100,000 population due to surface ozone from pyre burning. The findings suggest transformational system goals before the resurgence of a subsequent wave.
本研究调查了第二波新冠疫情期间空气污染导致的死亡率,即便在封锁期间,印度首都新德里仍有数千人死于这一波疫情。新德里是空气质量不健康的热点地区。在2021年第二波新冠疫情期间,观测到地表臭氧水平较高,这对肺功能有直接影响,从而使人们更容易感染新冠病毒。在95%的置信水平下,地表臭氧浓度与死亡率之间的相关系数为0.74。这项工作聚焦于新德里因新冠死亡率上升,露天焚烧丧葬柴堆导致空气质量变差所产生的可能影响及反馈,通过使用世界卫生组织的流行病学模型(AirQ+)进行估算。借助AirQ+定量估算出的死亡率为,每10万人口中因柴堆燃烧产生的地表臭氧导致1.27例额外死亡。研究结果表明,在后续疫情波次卷土重来之前需要转变系统目标。
