Outdoor Air Quality Monitoring

The World Health Organization (WHO) recommends guideline limits for key outdoor air pollutants to protect human health, based on evidence linking pollution exposure to respiratory and cardiovascular disease. In its 2021 global air quality guidelines, WHO suggests that annual average concentrations should not exceed 5 µg/m³ for fine particulate matter (PM₂.₅) and 15 µg/m³ for coarse particulate matter (PM₁₀), with stricter 24-hour limits of 15 µg/m³ (PM₂.₅) and 45 µg/m³ (PM₁₀) to limit short-term exposure spikes.

It also recommends limits for gases such as nitrogen dioxide (NO₂) at 10 µg/m³ annual mean, ozone (O₃) at 100 µg/m³ maximum daily 8-hour mean, sulfur dioxide (SO₂) at 40 µg/m³ over 24 hours, and carbon monoxide (CO) at 4 mg/m³ over 24 hours. These guideline values are not legal standards but serve as evidence-based targets for governments to reduce air pollution and lower risks of illness and premature death worldwide.
