Pollutant Standards Index
Pollutant Standards Index or PSI is like a report card that tells you how clean or dirty the air is outside. Just like you get a report card in school that tells you how well you are doing in your studies, the PSI tells you how good or bad the air quality is in your area.
PSI measures the amount of pollutants like smoke, dust, and gases in the air. These pollutants can come from many sources like cars, factories, and burning of fossil fuels. When there are too many of these pollutants in the air, it can be harmful to breathe and can lead to health problems.
The PSI is measured on a scale of 0 to 500, with 0 being the cleanest and 500 being the dirtiest. When the PSI is between 0 and 50, the air quality is considered good and safe to breathe. When the PSI is between 51 and 100, the air quality is moderate, which means that it may not be very healthy for people who have breathing problems.
When the PSI goes higher than 100, that means the air quality is unhealthy. This can lead to coughing, wheezing, and other health problems, especially for children, elderly people, and those with asthma. When the PSI is over 200, it is considered very unhealthy, and you should try to stay indoors and avoid going outside as much as possible.
So, in short, just like how you want to get good grades in school, we want the PSI to be as low as possible, so that the air we breathe is safe and healthy for us.
