C L , C H are concentration breakpoint.
I H , I L are index breakpoint.
There are six ranges based on which the quality of the air is determined. It can be
understood further by Table 5.2.
In these upcoming sections, we will try to understand the pollution from different
sectors, the relationship among the pollutants and how they are affecting AQI and
causing pollution. Later we will go into deep analysis and prediction will be done
and we will have a view on how COVID-19 is affecting air pollution and how it has
become a blessing in disguise to the environment.
5.4 Pollution from Different Sectors
From the smoke and ashes of a small cigarette to smoke of large chimneys of industries, there are pollutants everywhere. In the context of the current scenario, pollution
is increasing with the increase in technology. In the next sections, we will have a
brief walk through the different pollution sector prevailing in our environment [26].
From vehicles:
Growth of the economy of a country is paving a way for the growth of different sectors.
Many automobile sectors are growing and nowadays preferring more of private or
self-owned vehicles over public transport which leads to the growth of sales of car
worldwide. The emission of CO (Leading to production of carboxyhaemoglobin),
Hydrocarbon, VOC, different oxides of nitrogen (NO x ) takes place and apart from
that in heavy-duty vehicles, emission of particulate matters, lead particles takes place
which is harmful to respiratory tracks [27].
From Industries:
High growth in technology is developing the industries and thus developing a
large amount of pollutants. From the industries and wastes of industries emission
of different pollutants like (NO x ), sulphur dioxide (SO 2 ), ethylene, formaldehyde,
toluene, benzene, etc., takes place. Also smoke from chimneys and wastes from the
battery industries, ore and mining industries as well as burning of coal and fossil
fuels like natural gas; petroleum is polluting the environment a lot [28–30].
