The talks about air quality have been making the rounds even more ever since COVID-19 has taken the world by storm. Air pollution has been a consistent issue, ever since the industrial revolution. But it has increased drastically in the twenty-first century, as the world population and the number of vehicles continue to rise too.
Ever since lockdown was implemented worldwide, almost all countries have signified air quality becoming better. Of course, this is related to less human intervention and lesser traffic on the roads. With the emission of smoke and harmful chemicals going down, the air quality is bound to go up. But how is air quality actually measured?
There are a variety of factors, but the environment, in general, plays an important role too. For example, the air quality of remote rural areas is bound to be better than that of big metropolitan cities. Another factor can be seasonal changes, such as wildfires which can contribute to bad air quality even in areas based in the countryside. The infographic below explains how the air quality of a particular area can be determined.
