Delhi, October 23: The air quality in Delhi has improved slightly on Wednesday. According to the Air Quality Index (AQI) data, the major pollutants PM 2.5 at 154 in the 'Moderate' category and PM 10 at 192 in the 'Moderate' category, in Lodhi Road area.
A marginal improvement has been noticed and it can be attributed to the impact of the easterlies that have reduced the impact of the northwesterlies which have been bringing the biomass from stubble burning in the neighbouring states to Delhi.
According to SAFAR (System of Air Quality and Weather Forecasting And Research), a slight improvement in the AQI is forecasted for October 25 owing to change in wind direction as part of approaching western disturbances. High deterioration in AQI is expected in the first week of November now. Odd-Even in Delhi: Two-Wheelers And Vehicles Carrying School Kids Exempted, Chief Minister And Delhi Ministers to Follow Rule.
The Central environment secretary has said that to keep a check on the air pollution in the national capital, two things are required, first is to keep a check on the dust emission and second is to control waste burning. With winters approaching, people in the city are finding it very difficult to inhale the polluted air.
The odd-even traffic rule to be implemented from November is expected to bring some relief. However, with the increase in the stubble burning in the neighbouring states, the air quality seems to be degrading every day.
An AQI between 0 and 50 is considered 'good', 51 and 100 'satisfactory', 101 and 200 'moderate', 201 and 300 'poor', 301 and 400 'very poor', and 401 and 500 'severe'.
