The rains which lashed the national capital on Sunday failed to improve the air quality which remained in the 'very poor' category.?
However, authorities said the contribution of stubble burning to Delhi's air came down to two per cent.
Ministry of Earth Sciences' forecast body SAFAR said the city's Air Quality Index (AQI) was recorded as 350, which falls in the 'very poor' category with PM2.5 as the lead pollutant.
It added that though light showers will bring some respite, the air quality will again deteriorate from Tuesday due to poor ventilation conditions.
"Since wind direction is mainly from the eastern side and moderate rain is expected, the AQI will improve significantly and touch moderate category for Monday and then again degrade to poor category for next two days.
"The SAFAR effective fire count was observed as 815 but as winds are not favourable and rain is expected, the stubble contribution today will be just two per cent, down from 14 per cent yesterday," it said.
According to the data from the Indian Agricultural Research Institute (IARI), there were just 14 farm fires in Punjab and no such incident was recorded in Haryana and Rajasthan.
