Annual air pollution level of PM10 in Singapore 2013-2022

In 2022, the pollution of PM10 in Singapore increased by three point to 24 microgram per cubic meter. Singapore's air quality target by 2020 was to bring the PM10 level below 20 gram per cubic meter in the annual mean.

Sources of PM10

  PM10 refers to atmospheric particulate matter of 10 micrometers or less in diameter. Sources of particulate matter emissions include fuel combustion from electricity utilities, industrial activities, and transport. In Singapore, the main sources of air pollution are emissions from industries and motor vehicles. Periodically, the region's transboundary haze from land smoke and forest fires can affect Singapore's air quality. The worst haze episode in recent years was in 2015, from forest fires in Indonesia used to clear land for palm oil and rubber plantations. During this period, the Pollutant Standards Index hit the highest levels, affecting the PM2.5 and PM10 levels.

Measures for air quality in Singapore

  High exposure to PM10 pollutants can lead to health effects such as high blood pressure and heart attacks. To maintain good air quality and reduce the impact of air pollution on health, the Singapore government regularly reviews air emission standards for industries and vehicles. An integrated urban and industrial planning strategy, as well as development control, are used by the government to minimize air pollution. Complementary measures include strict enforcement programs and regular air quality monitoring. As a result, air quality remains good despite the densely populated urban landscape and the considerable industrial activity. The air is less polluted than in many Asian cities, making Singapore one of the countries with the best air quality.
