WHO global air quality guidelines

What the study found

Provides health-based guideline levels for major air pollutants and interim targets.

Limitations

Primarily ambient-air guidance; indoor source mixtures and specific cognitive outcomes require additional evidence.

Neurodesign interpretation

Neurodesign air research should not begin and end with CO2. Health-relevant particulate and gaseous exposures can be invisible to occupants while shaping long-term risk.

Possible design implications

Use in location, filtration and outdoor-air decisions while separately tracking indoor contaminants such as VOCs.

Why it stays in the corpus

Retain as the health-risk baseline for pollutants that enter or are generated around buildings.
