- Along with PM 2.5 and PM 10 in Delhi, PM 1.0 has also increased significantly.
- Between October 15 and November 15, the PM 1.0 level was 200 to 300 MGCM.
- PM1 is placed in the most dangerous category, many diseases can be the reason
- The alarming latest figures of PM 1.0 have been released in a report
This report explains what was the situation of pollution in Delhi-NCR, Haryana, Punjab and parts of western Uttar Pradesh during October to November 16, 2020 during Diwali and the days that followed. In the last week of October 2020, this year the PM2.5 level ranged from 250 to 500 MGCM. At the same time, between 5 and 8 November it was 600 to 700 MGCM and on 10 November it also crossed 1000 MGCM. Burning of the straw in Punjab and Haryana was also one of the reasons for the increase.

Similarly, the level of PM-10 was also the same and it was one and a half times higher than PM 2.5. According to figures from the Purple Air Network, PM 1.0 levels in the air ranged from 250–280 micrograms per cubic meter between 7 and 11 November. PM 1.0 is not counted in the air quality monitoring done by the Delhi Pollution Control Board and the Central Pollution Control Board. The report said that pollution levels in Delhi-NCR rose so much during the last two weeks that Particulate Matter levels destroyed all previous 4-year records. During this time the air quality reached the lowest level. The PM 2.5 and PM 1.0 levels in the air were found to be very high during the assessment conducted almost round the clock between 6 and 10 November.
In fact, a new network with smart and affordable sensors has been created in Delhi NCR and adjoining areas of Haryana, Punjab and Western Uttar Pradesh. NASA is funding this initiative initiated by RTI International in collaboration with IIT Delhi and other organizations. Purple air sensors have been used in this new sensor network. There are about 35 sensors currently working, providing real-time data on temperature and humidity as well as air quality. These sensor networks provide estimates of levels of PM 1.0 PM 2.5 and PM 10 in the range of 150 to 200 km of Delhi.
November’s ‘cleanest’ start in 5 years
PM1 is placed in the most dangerous category and it is because with this breath that it causes diseases like brain stroke and cancer. The report states that the PM 2.5 and PM 10 levels are significantly higher, including PM 1.0, in the morning air. It rises even more after the sun goes out. It is believed that the morning mist is related to the formation of leaves, grass and dew falling on the ground. Apart from this, the situation gets worse due to the burning of stubble in Delhi and NCR areas. Evaporation begins when the sun’s rays fall on the ground, and particles smaller than 2.5–3 μg that are present in the air combine to form 2.5–3 μg and larger particles.
Assessment in the report showed that the temperature varies from 3 to 5 degrees outside Delhi-NCR and inside the city. In the morning, the humidity is around 70 percent. Therefore, due to the excess of micron particles, due to moisture and low temperature, small particles join together to create mist.
How much danger is PM 1.0
A microgram-sized PM 1.0 is too small because the mucus of the lungs enters the bloodstream and enters the bloodstream. This can cause serious problems. This affects the way a human heart works. Serious heart diseases such as myocardia infection can occur. Extremely fine particles can also cause brain damage diseases such as Alzheimer’s and Parkinson’s. These particles can enter the olfactory epithelium inside the nose or into our bloodstream.
