What Is Air Quality Index? How It Can Be Improved?
All about Air Quality Index
These days a term AQI is very commonly used in the news channels or in various media. Some say AQI is increasing day by day and it affects our health very badly. But most of the people are unaware of this term AQI and how it is affecting their health and how to deal with it?
Air Quality Index (AQI) is an index tells the quality of air around us or in our area daily. It indicates whether the air around us is toxic, good, bad, etc. AQI is a very important parameter that tells you how much air around you is polluted or clean and how much this affects your body.
How AQI is calculated?
Environmental Protection Agency (EPA) calculates the AQI depending upon five major air pollutants i.e. ground-level ozone, particulate pollution or particulate matter, carbon monoxide, sulphur dioxide, nitrogen dioxide. There is the basic association with these five pollutants and the concentration for each pollutant is checked and whatever quality standard set for every pollutant, depending upon this you are informed regarding AQI of your area. The rating of AQI lies between 0 and 500. More value of AQI means the quality of air is very poor and bad quality air means more health concern.
Generally, if the AQI is 50, then the quality of air is considered good which means there is no any health problem and if the AQI is around 300, then it is hazardous for health and if the AQI value is 100, then this condition is satisfactory and in most of the region, it is expected to have 100 AQI level. This is the National Air quality standard. But in India, it may increase in several areas due to many reasons e.g. near Diwali AQI level increased very much in many areas. If AQI is around 100, then it is good but if it increased, then this is the matter of concern.
Different levels of AQI
1. AQI (0-50)
If AQI is 0-50, then it is good and green color is given to it which means it does not pose any health problem.
2. AQI (51-100)
If AQI is 51-100, then it is moderate and yellow color is given, that implies some special care is needed for people who are very sensitive to air pollution.
If AQI is 101-150, then this is considered Unhealthy for sensitive groups that include children, old people, unhealthy people suffering from some kind of allergy, lung diseases, heart disease or asthma and orange color given to this.
4. AQI (151-200)
If AQI is 151-200, then air is unhealthy and many people may have various health issues and the red color is given to it.
5. AQI (201-300)
If AQI is 201-300, then this means air is very unhealthy and people may have an asthma attack, heart attack, coughing, problem in breathing, ear infection, headache, eye irritation, etc. and purple color is given to this.
If AQI is 301-500, then this is considered Hazardous and acts as a health emergency warning that doesn’t come outside as there is a dangerous condition outside. In this condition, the entire population living in that particular area affected if they are outside and it may have some effects if they are inside. So, this is a very risky and dangerous condition and the maroon color is given to this.
You can check the AQI level online in your area very easily. Normally in India, the AQI level is around 100 and near Diwali, it may go around 280-300 in areas like Delhi, Gurgaon, Ghaziabad, etc that means air quality is very poor in India which means more health issues. There are a lot of Good Quality Air Purifiers available in India so you can choose the Best Air Purifier for your home as per your requirements.
Most people say they don’t smoke and drink so why they suffer from a heart attack? Or why they are suffering from various diseases? Or why small children are having health issues?
The reason behind this is high AQI that means poor air quality. So, it is suggested that you check AQI of your area first and then go outside. Installing an Air Purifier in our home has become a necessity these days.
That’s why it is said to wear a mask while going outside and also don’t burn crackers as this increases the concentration of pollutants in the air which increases the AQI. We can also use some Plants as Air Purifier at our home.
Therefore, if you want to live in good quality air then take some steps to improve the air quality.
