Air\u200b\u200d\u200b\u200c\u200d\u200b\u200d\u200c is something no human can live without. Literally, day in and day out, we breathe it without giving it a thought until all of a sudden, breathing becomes uncomfortable. Words such as air quality and air quality index would eventually become more meaningful to us. Most individuals use these terms interchangeably, but truth be told, they are different.<\/p>\n\n\n\n

Understanding how air quality differs from the air quality index is like being one step ahead in safeguarding your health against the effects of pollution.<\/p>\n\n\n\n

What Is Air Quality?<\/strong><\/h2>\n\n\n\n

Air quality<\/a> refers to the state or condition of the air around us in terms of how contaminated or pure it is. Clean air hardly contains harmful chemicals to humans. People who breathe polluted air might get allergens and other things that can make them feel uncomfortable.<\/p>\n\n\n\n

The common air impurities are dust, smoke, motor byproducts, products of burning fuel, factory wastes, and gases produced from burning fuels. When we breathe in these particles and gases, they can penetrate our lungs. Exposure to air pollution commonly causes chest pain and coughing, and one experiences difficulty in breathing.<\/p>\n\n\n\n

Children and old people with chronic respiratory diseases like asthma are usually the first ones to show these signs.<\/p>\n\n\n\n

Now let\u2019s talk about what is air quality index.<\/p>\n\n\n\n

The air quality index (AQI) is a numerical indicator that communicates environmental pollution in a simple and straightforward manner. The AQI turns pollution data into a scale represented by numbers and colors instead of the text of the data itself. This is done to help everyone get a grasp of the safety of the air instantly.<\/p>\n\n\n\n

An air pollutant concentration for a predetermined averaging period must be received from an air monitor or model in order to calculate the AQI. When combined, concentration and time indicate the air pollutant dose. The potency of air pollutants varies, and each pollutant has a different conversion function from air pollutant concentration to AQI. The values of its air quality index are usually categorized into ranges. A standardized public health advisory, a color code, and a descriptor are given to each range. <\/p>\n\n\n\n

The standard AQI scale varies between 0 and 500. The low end indicates good air and high end indicates bad air with respectively low and high health risks. \u200b\u200d\u200b\u200c\u200d\u200b\u200d\u200c <\/p>\n\n\n\n

You can see how good or bad the air is by looking at the colors.<\/p>\n\n\n\n
