Air pollution is when there are harmful levels of gases or particles in the air. Polluted air can impact our health and environment.

Examples of air pollutants are carbon monoxide, ozone, nitrogen dioxide, sulfur dioxide and PM2.5 and PM10 particles. In Victoria, air pollutants mainly come from industry, vehicles and wood burning.

EPA has a key role in reducing emissions that lead to air pollution. We regulate industry and monitor air quality across Victoria. Air quality information is available at EPA AirWatch.
