-- Air quality in the national capital continues to deteriorate. Air quality index (AQI) was recorded 232 on 19th Oct 2020 at 8:45 am. As per the air quality standards, AQI between 0 and 50 stands 'good', 51 and 100 as 'satisfactory', 101 and 200 as 'moderate', 201 and 300 as 'poor', 301 and 400 as 'very poor', and AQI from 401 to 500 is termed as 'severe'.
So yes, the current air quality in Delhi is 'poor' which is of course better than that had been in the last few months and years. Notably, the air quality of the national capital has been very poor and sometimes even hazardous to breathe in recent years, particularly in the months of October and November. Although a few insights are suggesting that the conditions may get slightly better in the days to come.
As per the Air Quality Early Warning System for the state of Delhi by The Ministry of Earth Sciences, ventilation index, the product of mixing depth and average wind speed was recorded 11,500 metre square per second on 18th Oct 2020 which decreased further to about 10,000 metre square per second on the very next day. This comes as a slight-favourable insight into the easy dispersion of pollutants.
The Central Pollution Control Board (CPCB) has asserted that the meteorological conditions in Delhi have not been quite favourable for the dispersion of pollutants last year. Delhi environment minister Gopal Rai has hyped the speculations of implementing odd-even in the state. The minister said that they may think of implementing another odd-even in the state of air pollution conditions deteriorate further.
Some of the major causes of deteriorating air quality in the state include stubble burning in Delhi nearby neighbouring states and firecrackers on festivals, marriage parties accounting for Delhi's severe PM2.5 pollution.For More Info Visit : https://www.nationalduniya.org/category/delhi
