Release of ultrafine particles from three simulated building processes

Building activities are recognised to produce coarse particulate matter but little is known about the release of airborne Ultra-Fine Particles (UFPs) below 100 nm in diameter. For the first time, this study investigated the release of particles in the 5-560 nm range arising from three simulated building activities: the crushing of concrete cubes, the demolition of old concrete slabs, and the recycling of concrete debris. The results confirm the previously unquantified release of significant UFPs and have health and safety implications. This has initiated further, on-going, detailed studies with local authorities aimed at establishing exposure guidelines for operational building sites.
