Air quality in Wayne, PA today

Air quality in Wayne, PA right now

Right now the modelled US Air Quality Index for Wayne, Pennsylvania, United States is 130, which falls in the "Unhealthy for Sensitive Groups" band (up to 150). People with heart or lung disease, older adults, children and teens should cut back on prolonged or heavy exertion outdoors.

The index is driven mainly by PM2.5, whose own sub-index is 130. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.

PM2.5 is 16 µg/m³, 1 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 16 µg/m³ against a guideline of 45; ozone is 96 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 11 µg/m³ (below the 24-hour guideline of 25).

Also this hour: UV index 2.9, carbon monoxide 162 µg/m³.

Every third hour of the CAMS forecast via Open-Meteo. US AQI uses rolling averages (24 h for particles, 8 h for ozone), so it moves more slowly than the hourly concentrations.
