Supreme Court of India Expressed its Concern over the Growing Smog Cover on New Delhi

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
