The Environmental Protection Agency has a list of criteria pollutants. One of those pollutants is particles smaller than 2.5 microns. And typically, if the concentration of those particles exceeds 35 micrograms per cubic meter, the air is considered unhealthy. When I looked at the map of pollution today (June 7, 2023), it showed that throughout the majority of New Jersey, the concentration is around 90 micrograms, which is two to three times higher than this unhealthy threshold. And actually, there is a location, I believe it's around Paterson, where the concentration is 140 micrograms, which is four to five times above the threshold.
