CASANZ Indoor Air SIG event: Indoor infiltration of smoke and other pollutants
22 June 2020
Infiltration of outdoor smoke into homes has become very topical recently, especially when bushfire smoke was blanketing parts of Australia, and public were being advised to stay indoors for some protection. A similar situation occurs in many southern Australian and New Zealand, towns and cities, where outdoor smoke levels frequently exceed air quality guidelines during cold calm winter nights.
In this AIR TALK, four presentations collectively address the topic of infiltration of outdoor air pollution into buildings and homes, indoor exposures and deposition onto indoor surfaces, and finally a look into mitigation measures. The presentations are:
- Dr Ian Longley: Winter air quality and outdoor-indoor air exchange in 85 homes in New Zealand’s most polluted town
- Dr Perry Davy: Sources of airborne particulate matter in a sample of New Zealand homes and the impact of ventilation/infiltration
- Brad Prezant: Infiltration and Surface Sampling Methodology for Assessing Indoor Deposition of Bushfire Ash
- Dr Amanda Wheeler: The use of portable HEPA air cleaners to improve residential indoor air quality during biomass burning events
