Air quality in Laiwu right now

Right now the modelled US Air Quality Index for Laiwu, Shandong, China is 125, 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 125. 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 45 µg/m³, 3 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 54 µg/m³ against a guideline of 45; ozone is 14 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 40 µg/m³ (above the 24-hour guideline of 25).

Also this hour: UV index 0.7, carbon monoxide 494 µg/m³.

Model vs measured

We found no measured PM2.5 sensor cell within 25 km of Laiwu, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.

Wildfire smoke

PM2.5 is forecast to reach 86 µg/m³ in the next 24 hours while NASA satellites detected 75 fire hotspots within 300 km in the last day (nearest about 3 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.

Advice for sensitive groups

At 125, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
