New Delhi: If you light an incense stick as part of your puja rituals, stop right now. As Delhi’s air quality turned ‘severe’ on Tuesday, this directive was part of an advisory by a government agency which also warned people against any outdoor activity. In the advisory, the Centre-run System of Air Quality Forecasting And Research (SAFAR) asked Delhiites not to rely on dust masks for protection as city’s air quality turned ‘severe’ on Tuesday for the first time this season.

The overall Air Quality Index (AQI) at 3 pm was 401, falling in the ‘severe’ category, the highest this season, Central Pollution Control Board officials said. SAFAR recorded the AQI at 410. An AQI between 0 and 50 is considered ‘good’, 51 and 100 ‘satisfactory’, 101 and 200 ‘moderate’, 201 and 300 ‘poor’, 301 and 400 ‘very poor’, and 401 and 500 ‘severe’.
The agency has advised the citizens of Delhi to avoid all outdoor activities and give a miss to walk Tuesday. “If the room has windows, close them, if the air conditioner provides a fresh air intake option then choose it, avoid burning anything such as wood, candle or even incense,” it said. The advisory also recommended frequent wet mopping and using masks known as N-95 or P-100 respirators only for outdoor activities. “Do not rely on dust masks for protection,” the advisory added.

Eighteen areas in Delhi recorded ‘severe’ air quality with the highest AQI at 4 PM recorded at Anand Vihar at 467, according to a data by the CPCB. Faridabad, Ghaziabad, Gurgaon and Noida recorded ‘severe’ air pollution, crossing the AQI of 400. Greater Noida’s air is also on the brink of turning severe, the data said. SAFAR has attributed the spike to “heavy stubble burning in the last 24 hours and calm winds”. About 28 per cent of pollution by PM2.5 (presence of particles in the air with a diameter of less than 2.5 micrometers) on Tuesday was caused due to regional factors like stubble burning, SAFAR officials said.

The Indian Institute of Tropical Meteorology (IITM) also spotted a large number of biomass fire spots through satellite imageries in neighbouring states of Delhi. A SAFAR official said pollution is likely to increase faster now with lead pollutant as PM10 because of new development as shown by SAFAR-model where it is indicating that western disturbances may hit over the western Himalayan region from October 31. “Lot of moisture is already getting introduced in Delhi sky as an early signature. The withdrawal will bring even more moisture in the air and result in fall in temperature. Upper winds already turned north-westerly (stubble site) today. Only favourable thing is that upper wind speed is moderate and fire counts are low,” the official said. The leading factor causing severe pollution levels also include moisture and heavy air. “The increase in surface wind speed can only prevent AQI to cross severe zone,” the official said.

NDTV – Dettol Banega Swachh India campaign lends support to the Government of India’s Swachh Bharat Mission (SBM). Helmed by Campaign Ambassador Amitabh Bachchan, the campaign aims to spread awareness about hygiene and sanitation, the importance of building toilets and making India open defecation free (ODF) by October 2019, a target set by Prime Minister Narendra Modi, when he launched Swachh Bharat Abhiyan in 2014. Over the years, the campaign has widened its scope to cover issues like air pollution, waste management, plastic ban, manual scavenging and menstrual hygiene. The campaign has also focused extensively on marine pollution, clean Ganga Project and rejuvenation of Yamuna, two of India’s major river bodies.
