These guidelines provide evidence-based recommendations on pollutant levels that pose minimal health risks. Community health nurses should understand these guidelines to effectively interpret National Air Quality Monitoring Programme data and communicate air quality risks to communities.

WHO Guidelines: 2021 Update

In 2021, the WHO significantly updated its Air Quality Guidelines (AQGs), making them considerably more stringent than the previous 2005 values. These updates reflect the growing body of evidence on the health impacts of air pollution, even at lower concentrations than previously thought harmful.

Pollutant	Averaging Period	2005 AQG Level	2021 AQG Level	Change
PM_2.5	Annual mean	10 μg/m³	5 μg/m³	50% stricter
PM_2.5	24-hour mean	25 μg/m³	15 μg/m³	40% stricter
PM₁₀	Annual mean	20 μg/m³	15 μg/m³	25% stricter
PM₁₀	24-hour mean	50 μg/m³	45 μg/m³	10% stricter
O₃	Peak season	Not established	60 μg/m³	New guideline
O₃	8-hour mean	100 μg/m³	100 μg/m³	Unchanged
NO₂	Annual mean	40 μg/m³	10 μg/m³	75% stricter
NO₂	24-hour mean	Not established	25 μg/m³	New guideline
SO₂	24-hour mean	20 μg/m³	40 μg/m³	Less strict
CO	24-hour mean	Not established	4 mg/m³	New guideline

Implementation Considerations for WHO Guidelines

The WHO acknowledges that achieving these guideline values can be challenging, especially in regions with high pollution levels. Therefore, they recommend a progressive approach with interim targets to guide gradual improvement in air quality. This approach recognizes that any improvement in air quality will yield public health benefits, even if the ultimate guidelines aren’t immediately achievable.

Interpreting Air Quality Data

Community health nurses should understand how to interpret air quality data in relation to these guidelines. This involves recognizing:

The difference between short-term (24-hour) and long-term (annual) exposure standards
The relationship between measured pollutant levels and potential health risks
How to translate technical air quality data into understandable health messaging for communities
The particular relevance of specific pollutants for different vulnerable groups

Important Nursing Consideration:

When communicating about air quality to communities, it’s important to emphasize that the WHO guidelines represent the levels associated with minimal health risk, not thresholds below which no health effects occur. Research increasingly suggests that there may be no “safe” level for certain pollutants, particularly PM_2.5. Any reduction in exposure can yield health benefits.
