Live: Hong Kong Air Quality Levels

The following maps and graphs, updated every hour, show the levels of pollutants from all 15 monitoring stations around Hong Kong as compared to the World Health Organization's guidelines for each pollutant. This helps illustrate whether the air you're breathing in Hong Kong is safe by WHO standards. WHO standards are much stricter than Hong Kong's own air quality standards.

And please take note of the following health hazards caused by air pollution when levels exceed WHO standards:

  • Irritated lungs, suppressed immune system and increased risk of respiratory infections (such as influenza). People with respiratory problems are most at risk of the effects of nitrogen dioxide.
  • Irritated nasal passage and mucus in the larynx and windpipe. Symptoms include coughing, chest ache and stabbing pains in the eyes and throat.
  • A weak respiratory system can cause severe deterioration of health in those with preexisting illnesses such as bronchitis and heart disease.
