The Air Quality Index (AQI) today was recorded at 312 with PM 10 at 142 and PM 2.5 at 72
The air quality in Delhi-NCR plunged into 'very poor' category again on Thursday and is expected to drop to 'severe' by tomorrow, as per the data provided by System of Air Quality and Weather Forecasting And Research (SAFAR).
The Air Quality Index (AQI) today was recorded at 312 with PM 10 at 142 and PM 2.5 at 72.
"The overall Delhi AQI is in the very poor category and is slowly declining and may further deteriorate by tomorrow towards the higher end of the very poor scale and may touch 'severe' in some parts of Delhi by November 22," stated the organisation in its advisory.
The pollution in Delhi can be attributed to two factors - slow surface winds in Delhi, and increasing fire counts compared to last week. Additionally, stubble level winds from the burning sites will contribute to the pollution.
However, transport-level winds are likely to be highly variable in direction and may fluctuate between Easterly to Northerly and may not bring significant stubble impact to Delhi tomorrow.
"The pollution level in Delhi which use to be around 100-200 is reaching 600 levels on AQI. It is very dangerous for people. It is increasing cardiovascular diseases along with lung-related diseases. People having chronic diseases and bronchitis asthma are the worst hit," said Manoj Kumar, Director of the Department of Cardiology at a private hospital.
Watch: Delhi pollution - an annual nightmare
The increase in the toxic air in and around Delhi is causing problems for the residents, making them susceptible to lung-related diseases and also cardiovascular diseases.
Pollution in Northern India spikes every during this season due to changing weather patterns and crop residue burning in the neighbouring states of Haryana, Punjab, and Uttar Pradesh. Additionally, a dip in temperature along with low wind speed also tends to trap air pollutants closer to the ground.
