ESSENTIAL TO HEALTH
Ensuring good air quality safeguards public health and is an important component of our quality of life.
As a city develops, air pollutants are inevitably produced. Without control measures, increased urbanisation and industrialisation threaten to degrade our air quality. While our air quality is relatively good as compared to major cities, our levels of sulphur dioxide and fine particulate matter, such as PM2.5, remain a concern.
PM2.5 refers to fine air particles that measure less than 2.5 micrometres in diameter. These air particles are often found in dirt, dust and soot, and are dangerous to health because they can lodge deep in our lungs.
