What are PM10

PM10 particulate matter have a diameter of under 10 microns. They float in the air and easily penetrate the human body. We distinguish between particles that are under 10 microns (PM10) and those that are under 2.5 microns (PM2.5). They penetrate our respiratory system and the smallest particles can enter our blood vessels and stay there.

  • 20.8% comes from traffic.

  • 1.5% comes from the port.
