## ANSWER

MINISTER OF STATE (INDEPENDENT CHARGE) FOR ENVIRONMENT, FOREST AND CLIMATE CHANGE

## (SHRI   PRAKASH JAVADEKAR)

- (a) & (b) The ambient air quality is being regularly monitored in Delhi by the Central Pollution Control  Board  (CPCB)  in  association  with  Delhi  Pollution  Control  Committee  and  National Environmental  Engineering  Research  Institute  (NEERI)  under  the  National  Air  Monitoring Programme  (NAMP).  The  monitoring  is  being  done  in  respect  of  Sulphur  Dioxide  (SO2), Nitrogen Dioxide (NO2) and Particulate Matter less than or equal to 10 micron (PM10) in Delhi at ten locations. Ambient air quality data during 2000-2015 of Delhi are annexed. The analysis of data reveals that, SO2 levels are within National Ambient Air Quality Standards (NAAQS) of 50 µg/m 3 (annual  standard)  during  2000-2015  and  shows  decreasing  trends.  The  data  relating  to NO2 levels are within NAAQS of 40 µg/m 3 (annual standard) during 2000-2002 and exceed the NAAQS during 2003 to 2015 and shows increasing trend during 2000-2008 and fluctuating trend thereafter.  The annual average of Particulate Matter (PM10) shows fluctuating trends from year 2000 to  2005,  and  after  year  2005  annual  average  of  PM10 shows  increasing  trend.  The  main contributors to PM10 are soil/road dust, airborne fly ash, secondary particles, combustion related sources etc.
- (c) CPCB has informed that an amount of ₹ 7,92,27,282, ₹ 7,25,83,500, ₹ 5,87,78,462 and ₹ 9,01,21,917 have been released to State and UT Governments including for metropolitan cities for  air  quality  monitoring  under  NAMP  during  2012-13,  2013-14,  2014-15  and  current  year respectively.
