Pollution falls, for now, largely due to weather in Delhi

Whether due to odd-even rule or not, air pollution levels in the city have begun to fall. While January 7 recorded PM2.5 level at 289, it was 225 on January 8 and 121 on January 9. Since the start of odd-even scheme, PM2.5 concentration has been running higher than January 2015 levels as measured by SAFAR. It was also lower than the level recorded on the same day in 2015.




The figures released by Central Pollution Control Board also show a fall in pollution levels after January 8. Though the cause of the fall is yet to be fully analysed, weather is one big contributor.
