mbient air quality monitoring carried out at
various cities/towns in the country, under National Air Monitoring
Programme (NAMP) provide air quality data that form the basis for
identification of areas with high air pollution levels and in planning
the strategies & development of action plans for control &
abatement of air pollution. Data generated over the years reveal that
particulate matter (SPM & RSPM) are exceeding more than the
permissible levels at many locations, particularly in urban areas. Air
pollution problem becomes complex due to multiplicity and complexity
of air polluting sources (e.g. industries, automobiles, generator
sets, domestic fuel burning, road side dusts, construction activities,
etc.). A cost-effective approach for improving air quality in
polluted areas involves (i) identification of emission sources; (ii)
assessment of extent of contribution of these sources on ambient
environment; (iii) prioritizing the sources that need to be tackled;
(iv) evaluate various options for controlling the sources with regard
to feasibility and economic viability; and (v) formulation and
implementation of most appropriate action plans. Source apportionment
study, which is primarily based on measurements and tracking down the
sources through receptor modeling, helps in identifying the sources
& extent of their contribution. The Auto Fuel Policy document of
Government of India also recommended for carrying out source
apportionment studies. Accordingly, source apportionment studies have been initiated in six major cities viz. (i) Delhi ; (ii) Mumbai; (iii) Chennai; (iv) Bangalore ; (v) Pune; and (vi) Kanpur. The study would focus on apportionment of fine particulates (PM 10 & PM 2.5 ), being most critical. Besides, separate projects on Development of emission factors for vehicles and Development of emission profiles for vehicular as well as non-vehicular sources have also been taken up, which would provide necessary inputs to source apportionment studies. Details of the projects, executing institutes and approximate costs are as follow: |

The scope for source apportionment studies includes preparation of emission inventories, monitoring of ambient air quality for various pollutants (SPM, PM 10 , PM 2.5 , SO2 , NO x , CO, HC, VOC, etc.) at selected locations (07 – 10 locations covering different land use viz. residential, industrial, kerbside, background, etc.), chemical speciation of PM 10 & PM 2.5 as well as source emissions, application of receptor (CMB8) & dispersion models to assess the contribution from various sources, future projections and evaluation of various control options to develop cost-effective action plans. |
