Air Pollution: What Are We Breathing And How It Harms Our Health
The air quality of the national capital turned "poor" and the situation would further deteriorate in the next few days, according to central government agency SAFAR, which monitors air pollution. The day-long average of particulate matter PM 2.5 and PM 10 were 178 and 94 micrograms per cubic metre, respectively, while the air quality index or AQI of the Central Pollution Control Board was poor. The AQI is a yardstick to measure how clean the air is at a specific location, while PM 2.5 is an air pollutant made up of a complex mixture of dust, soot and smoke, and can cause health issues. A "poor" Air Quality Index essentially means that people will have breathing discomfort on prolonged exposure to such air. On further dip in air quality, AQI will turn "very poor" and "severe". In this episode of Doctors On Call, we give a quick run down on how air pollution affects us and what you can do about it.
