- 22 new locations prove consistent drop in air pollution caused by vehicular traffic in Delhi
Latest set of ambient air data collected by mobile teams of the Delhi Pollution Control Committee on 22 locations across Delhi through mobile dust samplers on Thursday (7th January, using the Light Scattering Technique, further shows a consistent trend of declining levels of PM2.5 air pollution levels due to the implementation of odd/even rule for four wheeled vehicles.
With the latest 22 locations, the mobile teams of Delhi Pollution Control Committee have so far collected ambient air data from 112 locations, this is part of the biggest exercise in the national capital to collect air data from every corner of the national capital.
(Please find attached the data of air pollution levels in latest 22 locations)
IMPORTANT FINDINGS :
· In 13 of the 22 locations, PM2.5 (ug/m3) was recorded at less than the level of 300.
· These 22 locations fall in higher population density areas of the national capital.
· All scientific studies show major source of PM2.5 during winter months is the vehicular pollution.
· The recording of PM2.5 in the latest 22 locations further shows the consistent trend of declining levels of air pollution caused by vehicular traffic following the implementation of the odd/even rule for four wheeled vehicles.
· PM10 levels in different parts of Delhi are higher than PM2.5
· Primary source of PM10 air pollution at this time of the year is dust arising from various sources, including construction material, burning of leaves and other kinds of waste in the open and wind blown dust.
· It is clear that levels of PM10 can be brought down only if NCR towns take proactive steps to reduce sources of air pollution in their respective areas.
