Life of people in Delhi will get even worse as already poor air quality in the capital will degrade further in next two days. According to System of Air Quality and Weather Forecasting and Research (SAFAR) stations, air pollution in Delhi will see a hike in the levels of PM 2.5 that was hovering around 200 micrograms per cubic metre yesterday. The rise in pollution levels will be due to the influx of pollutants from the Indo-Gangetic plains.
SAFAR scientists predicted the rise after seeing the elevated graph of air pollution. On Monday, level of PM 2.5 in Delhi was recorded 189 while yesterday it was around 200, similarly, 24-hour average of today’s PM 2.5 level is expected to 210 which will further increase tomorrow. “It is due to influx of pollutants from distant sources, mostly due to the north-easterlies from the Indo-Gangetic plains, an area which stretches from Kolkata to Rajasthan,” Gufran Beig, Chief Project Scientist of SAFAR told PTI.
Levels of PM 2.5 and PM 10 both are very high in the Delhi region especially in areas like Anand Vihar, Mandir Marg, Okhla, Punjabi Bagh and R K Puram. Scientists noted that although the PM 2.5 is rising but PM 10 is stable. Since, PM 10 cannot travel long distances, this suggests that worsening air quality is due to external factors and not due to the local factors.
The worsening pollution will create respiratory problems especially for asthmatic people and those who are suffering from respiratory illness. According to a survey, Delhi has the worst air quality among all the cities in the world where PM 2.5 and PM 10 levels are nearly 5-10 times in some areas of the capital. Permissible levels of PM (particulate matter) 2.5 and PM 10 are 60 and 100 micrograms per cubic metre respectively. However, 541 and 1431 were the real-time PM 2.5 and PM 10 levels of Anand Vihar at 7 PM while the corresponding figures were 454 and 182 at Punjabi Bagh.Tags: air pollution, air quality, delhi, pollution
