These particles cause less severe health effects mostly in the upper respiratory tract. When particle pollution levels are high, take steps to limit the amount of air you breathe in while you’re outside. For example: Think about spending more time indoors, where particle pollution levels are usually lower. Choose easier outdoor activities (like walking instead of running) so you don’t breathe as hard. Currently, the WHO identifies safe levels of PM10 - particulate matter measuring under ten micrometres - as under 20 micrograms per cubic metre. This is much lower than the EU's safe particulate matter level, which stands at 40 micrograms per cubic metre. 10.
