Rains Wash Away Delhi's Pollution, Bringing Relief To Residents Ahead Of Diwali

The rain showers that graced Delhi and its surrounding areas on Friday provided a much-needed relief from the deteriorating air quality in the national capital region. The intermittent rainfall throughout the day played a significant role in improving the air quality by settling suspended particulate matter, especially PM 2.5 and PM 10. This brought relief to residents who have been contending with hazardous air quality levels in recent days.

The Central Pollution Control Board (CPCB) reported a substantial improvement in the Air Quality Index (AQI) at various monitoring stations in Delhi. The AQI, which had previously reached the 'severe' and 'severe plus' categories, showed a noticeable reduction, indicating 'moderate' to 'poor' air quality in several areas. The AQI scale categorizes levels from 'good' (0-50) to 'severe plus' (above 450).

With Diwali approaching, concerns had risen about the potential worsening of air pollution due to the traditional bursting of firecrackers during the celebrations. However, the air quality is expected to continue improving, supported by favorable wind speeds for pollutant dispersion. Reports from PTI indicate that the wind speed is anticipated to increase to around 15 kilometers per hour on Saturday, aiding in the dispersion of pollutants before Diwali on November 12. Officials from the India Meteorological Department (IMD) also mentioned that a shift in wind direction from northwest to southeast, influenced by a fresh western disturbance affecting northwest India, would help decrease the impact of smoke from stubble burning.

Restrictions outlined in the final stage of the Central government's Graded Response Action Plan (GRAP) for Delhi-NCR have now been enforced in the national capital. These measures encompass a prohibition on all construction activities and the entry of pollution-emitting trucks into Delhi. Simultaneously, the Delhi government has delayed the implementation of the Odd-Even vehicle rationing scheme following the Supreme Court's stern assessment of the administration's anti-pollution efforts.

"Significant improvement has been observed in Delhi's air quality. Pollution levels, previously categorized as severe plus with an Air Quality Index (AQI) exceeding 450, have now ameliorated to around 300. Consequently, the government has opted to defer the implementation of the Odd-Even scheme during the period of November 13-20," stated Gopal Rai, Delhi's Environment Minister, during a press conference at the Delhi Secretariat.
