PSI

PSI is the Pollutant Standards Index, a measurement used to indicate the level of air pollution in a given area. It is a key metric for public health advisories, such as the distribution of N95 masks during periods of high haze.

Why it’s in the news: It is in the news due to a haze-related public health initiative to distribute protective masks to vulnerable individuals when the PSI exceeds 200.
