ABSTRACT:
Air Pollution is an
escalating problem worldwide fuelled by increasing anthropogenic activities, speedy development, rapid industrialization,
transportation, superfluous use of fossil fuel consumption, increasing global
power needs, etc. Also the diverse meteorological factors influence our
environment to a great extent. Population explosion has led to remarkable
increase in vehicular population. The use solely depends upon the lifestyle of
the citizen. Any change in the lifestyle has a remarkable
effect on the air we breathe. A comprehensive database for pollution levels
from the year 2006 to 2010 was analyzed for a main traffic intersection and a
non-traffic area in Delhi (India). The paper asserts that pollutant
concentration levels on weekend are lower than those on weekdays (increase on
Sundays with respect to weekdays is CO 2.98 times, PM2.5 1.18 times, NO 1.62
times, NO2 5.76 times, SO2 1.27 times and O3 1.15 times). The pollution levels have been found to attenuate on public holidays
and weekends. Pollution can hence be related to the weekly cycle of human activities. Pollutions due to vehicular
emissions on roads, rails, air or water all serve as major sources of
pollution. Hence, viably possible solutions for pollution control can also be
achieved by controlling the magnitude of traffic flow on roads.
