PM10 emerged as the dominant pollutant in Delhi on Wednesday, marking a shift from the previous three days when PM2.5 was the dominant pollutant. PM10 is generally associated with coarse particulate matter, including road dust and construction dust.

Delhi air pollution: Top reasons for toxic air

According to the Decision Support System (DSS), transport emissions contributed 15.5 per cent to Delhi's pollution on Wednesday, while stubble burning accounted for 20.2 per cent.

Delhi's other contributing sectors included industries (2.9 per cent), waste burning (1.3 per cent), construction (2.2 per cent), road dust (1.1 per cent), residential sources (3.8 per cent) and other sectors (1 per cent).

Among the NCR districts, Ghaziabad contributed 7 per cent, Rohtak 3.8 per cent, Gurugram 2.7 per cent, Sonipat 2.2 per cent, Jind 1.8 per cent and Bhiwani 1.3 per cent. Other sources accounted for 28.5 per cent of the pollution.

Meanwhile, satellites detected 467 farm fires across the six study states on November 4, including 151 in Punjab, 10 in Haryana, 33 in Uttar Pradesh, 111 in Rajasthan, five in Uttarakhand and 157 in Madhya Pradesh. No farm fires were detected in Delhi.

A total of 4,800 residue-burning events have been detected across the seven states or UTs, including Delhi, between September 15 and November 4, according to the Consortium for Research on Agroecosystem Monitoring and Modeling from Space (CREAMS) Laboratory of the ICAR-Indian Agricultural Research Institute.

These included 2,347 in Punjab, 62 in Haryana, 392 in Uttar Pradesh, two in Delhi, 949 in Rajasthan, 183 in Uttarakhand and 865 in Madhya Pradesh.

Delhi is currently under Stage II of the Graded Response Action Plan (GRAP), which is invoked when the city's air quality enters the very poor category.

The 12-point action plan includes intensified mechanical and vacuum-based road sweeping, water sprinkling, stricter dust control at construction sites and increased inspections to curb pollution from construction and demolition activities.
