Particulate pollution poses a great
threat to the health quality of humans and has been found to have
caused many respiratory problems and may also influence diabetes
mellitus. This study is aimed to establish a connection between the
mortality statistics and the PM2.5 concentration and discuss the
variation trend during the first and the second wave of COVID-19
pandemic in India. The air quality index related to PM2.5 was
recorded from September 1, 2020, to September 30, 2020, and April 1,
2021, to May 31, 2021. Mortality trend during this duration was
plotted with respect to the PM2.5 concentration for three heavily
polluted Indian cities, namely, Delhi, Lucknow, and Mumbai. The
correlation (R2 value) in Delhi during the second wave of COVID-19
was only 8.21%. During the first and second waves, the correlation
in Lucknow was 0.18% and 5.49%, respectively. During the first wave
of COVID-19 in Mumbai, a 1.94% correlation was seen. Because of the
poor correlation values, no well-defined link between mortality and
PM2.5 concentration could be established. The R2 values of 26.91%
and 25.59% for Delhi during the first wave and Mumbai during the
second wave, respectively, exhibit a clear link between mortality
and PM2.5 concentrations. This paper attempts at establishing a
relationship between PM2.5 concentration and mortality with regard
to the first and second wave of the pandemic.
