摘要

In the event of a defect in the building drainage system, a cross-transmission route exists which connects one part of a building to another.Turbulence of discharging wastewater can generate pathogenic bioaerosols which can be transported via airflows within the system and can increase the inhabitant exposure to disease.This paper introduces the work of the new research group (PRoBE) established at Heriot-Watt University to define and characterize the formation and transmission of bioaerosols within building drainage systems and to assess the potential infection risk for building occupants.Preliminary research has already confirmed significant findings: (i) the building drainage system becomes fully contaminated whenever pathogenic material is introduced into the system; (ii) bioaerosols can be easily formed by the normal flushing mechanism and the turbulent discharge of wastewater within the system; (iii) bioaerosols can be carried in system airstreams and if the water trap seal is lost these bioaerosols can enter the building; (iv) the ingress of bioaerosols from the building drainage system into the building can result in contamination of every surface in a room.
