Delhi's Air Quality Deteriorates to 'Severe' Level, Prompting GRAP 4 Restrictions
Preview
Delhi's air quality has deteriorated significantly, with the Air Quality Index (AQI) reaching a severe level of 409. This has prompted the reimposition of GRAP 4 restrictions, which are the most stringent measures under the Graded Response Action Plan (GRAP) to combat air pollution.The severe AQI level indicates that the air quality poses a serious health risk to the entire population, not just those with pre-existing conditions. The primary pollutants contributing to this hazardous condition include fine particulate matter (PM2.5) and particulate matter (PM10).Several factors have contributed to the current air quality crisis in Delhi:
Lack of Rain and Wind: The absence of rain and wind has exacerbated the situation, as these natural elements help in dispersing pollutants.
Local Emissions: High traffic density and industrial emissions are also major contributors to the poor air quality.
The GRAP 4 restrictions include stringent measures such as the complete ban on construction activities, the closure of schools, and restrictions on the use of private diesel vehicles. These measures aim to reduce the emission of pollutants and improve air quality.Despite these efforts, the air quality in Delhi remains a significant public health concern, and ongoing measures are necessary to address the root causes of pollution and ensure long-term improvements.
