What is the Air Quality Index (AQI)?
The AQI is an easy way to correlate levels of different pollutants to one scale. The higher the AQI value, the greater the health concern.
Weather / Air Quality
A dense fog advisory and an air quality alert have been issued for parts of New York and New Jersey, creating hazardous conditions for commuters and raising health concerns for sensitive groups. The advisory is in effect until mid-morning,...
The combination of dense fog and stagnant air is creating a double hazard. The fog reduces visibility, making driving dangerous, while the lack of wind allows pollutants to accumulate, degrading air quality.
**Fog Advisory:** Motorists are advised to slow down, use headlights, and increase following distances. Bridges and overpasses are particularly prone to fog.
**Air Quality Alert:** The primary pollutant of concern is fine particulate matter (PM2.5), which can penetrate deep into the lungs. Sources include vehicle exhaust, heating emissions, and other combustion-related activities. Wildfire smoke may also be a contributing factor.
**How to Prepare:** - **Limit Outdoor Activity:** Sensitive individuals should reduce prolonged or heavy exertion outdoors. - **Stay Indoors:** Keep windows and doors closed and use an air purifier if possible. - **Drive Safely:** If travel is necessary, allow extra time and drive cautiously in foggy areas.
**Who This Affects Most:** - Individuals with respiratory or heart conditions - Children and older adults - Pregnant women
The AQI is an easy way to correlate levels of different pollutants to one scale. The higher the AQI value, the greater the health concern.
Stay indoors, use an air purifier, run your AC on recirculate, and avoid activities that increase indoor pollution. If you must go outside, wear an N95 mask.
Consult your personal physician if you experience new or worsening respiratory symptoms.
