Abstract

There is little knowledge on the effect of water-only cleaning on chemical and microbiological exposure indoors. Here the aim was to evaluate the effect of water-only cleaning and ventilation rates on exposure. One classroom with demand-based mechanical supply and exhaust ventilation operated normally for 8 weeks (120 – 400 L/s) and after that it was set to set to constant flow (260 L/s) for 8 weeks. There were 4 weeks of regular cleaning followed by 4 weeks of water-only cleaning under each ventilation condition. Chemicals, particulate matter, and microbial surface and airborne concentrations were investigated for each period. Concentrations were low throughout the 16-week study, with a slightly lower chemicals concentrations during the water-only cleaning periods. However, it was not possible to ascertain this was due to the change of cleaning practice.
