Delhi pollution, AQI, Grap 1 imposed: The deteriorating air quality index (AQI) in Delhi and the neighbouring national capital region (NCR) has triggered government action and the Commission of Air Quality Management (CAQM) has imposed Grap Stage-I restrictions under the Graded Response Action Plan (GRAP). Despite of earlier predictions that Delhi AQI would recover from the dust storms that blew across the NCR this week, the worsening of pollution levels in the entire region forced the government's CAQM sub-committee to impose restrictions.
After the comprehensive review by the CAQM sub-committee, it was decided that Grap-I would be imposed as the NCR area experienced no respite from strong winds that brought along sand and dust from far off regions, triggering a short, but serious episode of pollution.
As part of the immediate relief measure to counter worsening AQI in Delhi and surrounding areas, the authorities have issued orders to enforce pollution regulations strictly, increase dust control measures and increase supervision at construction sites. Delhiites have also been advised to reduce outdoor activities and utilise means of public transportation as much as possible.

May 15: The capital witness a sharp drop in air quality index, with situation worsening as time passed.
May 16: Delhi clocked an Air Quality Index (AQI) reading of 278 — considered in the 'poor' category.
May 17: Capital and surroundings areas experienced another bout of dust storm and as per Indian Institute of Tropical Meteorology (IITM) and India Meteorological Department (IMD) forecasts, air quality in Delhi and NCR is expected to stay in the lower side of 'poor' range.
