TrueBreath - Smoke Equivalence Calculator - Beijing

Breathing air in Beijing (北京) is equivalent to smoking approximately 6.3 cigarettes per day, based on the current PM2.5 level of 139.0 μg/m³.

Beijing (北京)'s current PM2.5 level is 139.0 μg/m³. The WHO safe limit is 15 μg/m³ for 24-hour exposure. This exceeds the safe limit and poses health risks.

With a PM2.5 level of 139.0 μg/m³, Beijing (北京)'s air quality poses significant health risks, especially for sensitive groups. Prolonged exposure can lead to respiratory issues, cardiovascular problems, and reduced life expectancy.

The Real-Time Air Quality Index (AQI) in Beijing (北京) is 139. This is considered Unhealthy for Sensitive Groups. AQI values above 100 indicate unhealthy air quality, especially for sensitive groups.

The primary pollutant affecting Beijing (北京)'s air quality is PM2.5. This pollutant is the main contributor to the current AQI of 139 and PM2.5 level of 139.0 μg/m³.

Beijing (北京)'s current PM10 level is 77.0 μg/m³, while PM2.5 is 139.0 μg/m³. PM10 particles are larger (2.5-10 micrometers) and less harmful than PM2.5, which can penetrate deep into the lungs and bloodstream.

The current ozone (O3) level in Beijing (北京) is 0.9 μg/m³. Ozone is a harmful gas that can cause respiratory problems, especially during physical activity. The WHO guideline for 8-hour exposure is 100 μg/m³.

The nitrogen dioxide (NO2) level in Beijing (北京) is currently 29.3 μg/m³. NO2 is primarily produced by vehicle emissions and industrial processes. High levels can worsen respiratory conditions and increase susceptibility to respiratory infections.
