    PM2.5 are particles concentrations 2.5 micrometres or less in diameter. They are largely produced from human sources, in particular burning wood or coal for home heating. PM2.5 is a component of PM10 and is associated with similar health effects, ranging from respiratory irritation to some forms of cancer.
