Supreme Court of India Expressed its Concern over the Growing Smog Cover on New Delhi
The Supreme Court of India on 6 October 2012 expressed its concerns on
the growing smog cover over the National Capital, which is caused due to
the pollution created due to the increase in the number of vehicles in
the Capital. The Apex Court made a decision to take a call on examining
the problems and then further suggest and identify the remedial
measures.
The Supreme Court Bench of three judges that was
headed by the Chief Justice of India Altamas Kabir and included Justices
S.S. Nijjar and J. Chelameswar, while hearing the petition related to
the disposal of toxic waste in Bhopal agreed to look into the matter of
excessive smog in a due course of time.
Reasons identified for
the growing level of smog in the environment of Delhi included vehicular
pollution i.e. the bad fumes created by the vehicles on road. The
public carriers in the state by now are fitted with the CNG kits but the
growth in the number of diesel operated vehicles like SUV’s and sedans
in the city is the main cause of growing on-road pollution. The growing
pollution may cause different kind of health hazards due to the presence
of highly toxic gases in the environment.
Smog and its harmful effects
Smog
in itself is the mixture of smoke and fog, which is the combination of
pollutants created from industries and vehicles. At present, it is
generally visible over the big cities in form of yellow cloud covering
the horizon during sunrise and sun-set. One can see the smog cover in
the sky even during the hot summer days when the wind density is low and
weak. Because of its toxicity, the smog umbrella in the sky is also
harmful for human health because of the toxicity level present in its
atmosphere. The smog also forms ground level ozone that can be termed as
bad-ozone, but is harmful for old age people, children, and people
suffering from asthma, bronchitis, emphysema and other diseases related
to heart and lungs.
Photochemical Smog
Photochemical
Smog is basically formed by the chemical reaction of nitrogen oxides
and volatile organic compounds in presence of sunlight and the term was
first time used and described during 1950s. The mixture of air
pollutants may include aldehydes, peroxyacyl nitrates, nitrogen oxides,
like nitrogen dioxide, troposphere ozone and other volatile organic
compounds
