Delhi’s air quality index (AQI) plunged to 256 from 310 on the previous day, as per the System of Air Quality and Weather Forecasting And Research (SAFAR).
Values of both the Particulate Matters (PM) – 10 and 2.5 – were recorded 207 and 107 micrograms per cubic respectively.
In short range weather and air quality forecast, SAFAR said, “AQI today indicates ‘poor’ air quality. For the next two days (13th, 14th), winds are likely to be low to moderate. Partially cloudy conditions and moderate mixing layer height (~ 1 km) are likely to keep air quality within ‘poor’ during noon time or ‘lower end of very poor’ during night and early morning hours for the next two days. From 15th onwards air quality is likely to improve due to relatively high wind speeds but within ‘poor’ or ‘lower end of very poor’ category.”
In a health advisory, SAFAR recommended that outdoor activities stop early in the morning and after sunset.
“Avoid prolonged or heavy exertion. Go for a short walk instead of a jog and take more breaks. Stop any activity level if you experience any unusual coughing, chest discomfort, wheezing, breathing difficulty, or fatigue.If the room has windows, close them. If the air conditioner provides a fresh air intake option, keep that closed. Avoid burning of wood, candles or incense. Keep the room clean – dont vacuum. Do wet mopping to reduce dust.Masks known as N-95 or P-100 respirators may only help if you go out,”
