While the air in the national capital region was cleaner this Diwali as compared to 2016, the level of major pollutants remained far above permissible limits, as per a report by the Central Pollution Control Board (CPCB) and the Delhi Pollution Control Committee (DPCC). According to US Embassy’s pollution monitoring system, the NCR region had crossed the pollution danger level with extremely high PM 2.5 content in the air.
What is PM 2.5?
PM 2.5 is an atmospheric particulate matter of diameter of fewer than 2.5 micrometres, which is around 3 per cent the diameter of a human hair. It causes respiratory problems and reduces visibility. PM 2.5 particles can only be detected with the help of an electron microscope because they are so small.
The last 10 days data of the Central Pollution Control Board (CPCB) shows the city’s PM (Particulate Matter) 2.5 concentration has almost doubled already.
What are its health implications?
As per studies, it could lead to premature death from heart and lung disease. Due to their smaller size, the PM 2.5 particles can easily bypass the nose and throat and can easily enter the circulatory system. The particles can also lead to cause chronic diseases such as asthma, heart attack, bronchitis and other respiratory problems.
How to save yourself from PM 2.5
1. Use air purifier equipped with a High-Efficiency Particulate Air filter (HEPA) filter, which can remove fine particles from the air.
2. Try to stay as much indoors, closing all windows that allow the entry of polluted air.
3. Avoid burning candles or other things which can emit smoke when you stay indoors.
4. Eat food that can increase your body’s resistance against PM 2.5.
