The ambient air quality is monitored in Delhi since 1984-1985 by the
Central Pollution Control Board (CPCB). Of late, Delhi Pollution Control
Committee (DPCC) is also monitoring ambient air in Delhi. The data on
ambient air so collected, is collated, complied, processed and published
by CPCB to know the trend. Apart from other sources, the main reasons
of air pollution in Delhi are vehicular exhaust emission and
re-suspension of roadside dust. Different fuels, i.e., diesel, petrol,
CNG, LPG, etc., are used in vehicles in Delhi. There in an decreasing
trend in the levels of Sulphur Dioxide in ambient air during 1995-2010
in Delhi due to reduction in sulphur content in diesel, apart from other
reasons. This was stated by Shrimati Jayanthi Natarajan Minister of
State (Independent Charge) for Environment and Forests, in a written
reply to a question in the Lok Sabha today.
She further stated that the introduction of CNG vehicles in Delhi began
gradually from the year 1999. By 2003, plying of diesel buses,
petrol/diesel three –wheelers and petrol/diesel taxis for public
transport have stopped completely. The trend or change in ambient air
quality is Delhi pre and post CNG implementation may not be solely
attributed to implementation of CNG.
The Minister further stated that the other steps taken by the
Government for improvement in quality of air in metro cities includes,
tightening of industrial emission norms, management of municipal,
hazardous and bio-medical wastes, strengthening air monitoring network,
source apportionment studies for particulate matter in ambient air in
six cities, strengthening public transport including metro rails in
select cities, preparation and implementation of action plans for select
cities & critically polluted areas, public awareness, etc, the
Minister added.
