Daily Air Quality Update (2024)

FAQs

What is air quality today in NJ? ›

48 AQI. The air quality is generally acceptable for most individuals.

In many places, action days are called when the AQI is forecast to be Unhealthy, or Code Red. In this case, everyone should reduce exposure to air pollution, but especially the members of the sensitive group for the particular pollutant.

Pollutants come from many human activities such as factories, power plants, dry cleaners, cars, trains, airplanes, and buses, as well as from natural sources.

The good news is that air quality has already drastically improved from 1980 to recent years. This trend can continue through more public transportation, low-emissions or electric vehicles, and renewable power generation in place of fossil fuels.

Think of the AQI as a yardstick that runs from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. For example, an AQI value of 50 or below represents good air quality, while an AQI value over 300 represents hazardous air quality.

Newark-NYC, Camden metro, and Bergen and Mercer counties have most ozone-polluted air.

In 2021, New Jersey had exceedances of the ozone and fine particulate matter (PM2. 5) National Ambient Air Quality Standards (NAAQS).

Air pollution levels are measured daily and ranked on a scale of 0 for perfect air all the way up to 500 for air pollution levels that pose an immediate danger to the public. The AQI breaks air pollution levels into six categories, each of which has a name, an associated color, and advice to go along with it.
