On Saturday, the air quality was in the ‘satisfactory’ category, with PM10 and
PM 2. However, this year, there was a dip in the air quality level on June 13
due to dust storms in western India that pushed the air quality level to ‘severe
plus’, bringing to light that emergency level pollution could be a ‘summer-time
problem’ too.New Delhi: Delhi might have recorded more rainfall than the
season’s average in the last two months, but the ongoing showers have failed to
give any "good" air quality day till now. At least two days continuous rain is
required to clean up the atmosphere.Experts had also warned that there are some
particulate matters (PM) whose size varies between 0. The air quality has
touched the "severe" level four times till now this year.8 mm of rainfall till
Saturday, while the average is 129.0 mm.The continuing summer months are the
only time when Delhiites can expect to breathe easy. Since June 1, when the
monsoon season officially began here, Delhi has recorded 217.An Air Quality
Index (AQI) between 0-50 is considered "good", 51-100 "satisfactory", 101-200
"moderate", 201-300 "poor", 301-400 "very poor", and 401-500 "severe". D13.The
national capital has not seen a single day in terms of ‘good’ air quality this
year despite recording more rainfall than the season’s average.In fact, the
national capital has not seen a single day in terms of "good" air quality this
year.
For the most part of July, the level has remained within the "satisfactory"
category (17 days). However, the rains failed to wash away some of the deadly
air pollutants in the city’s air and according to experts, that is due to the
intermittent spells of rain. The month of July has received 177. Four days were
recorded in the "moderate" category.5 mm average.1 micron and one micron, which
continue to be present in Delhi’s air even after heavy China Special
Precision Air Conditioners rains.The maximum number of days (92) since
January this year was recorded in "moderate" category, followed by "very poor"
(40). Even last year, Delhi didn’t witness a single day, which could be termed
"good", as per data provided by Safar (System of Air Quality and Weather
Forecasting and Research), under ministry of earth sciences. It will be in the
‘good’ category once it rains like that," said Scientist Gufran Beig, Project
Director, SAFAR.9 mm rainfall, more than the 194.5 levels at 99 and 47
microgramme per cubic metre (ug/m3) respectively.Meanwhile, the meteorological
department has said that the rainfall Delhi has received till now is in excess
of the seasonal average.
The Supreme Court mandated Environment Pollution
(Prevention and Control) Authority (EPCA) had earlier said that the secondary
particles like nitrates and sulphates, which form in the air from primary
particles, might be difficult to wash off. "During the monsoon season, air
quality will be ‘good’ when there is continuous rain for a day or two so that it
washes off all the pollutants in the air which is not happening right now
