There is a gap in our understanding of physical, chemical and biological characteristics of household dust, which has direct relevance to human health. As a result there is a need to investigate household dust for substances of very high concern (SVHC) to human health and their risks assessed. Specifically, key toxic chemicals (e.g. bisphenols, flame retardants, asbestos etc.) and physical parameters (e.g. particulate matter) need to be determined in household dust and exposure-based risk models determined. Recent industry and government reports have highlighted significant concern from SVHC within home environment, with respect to their carcinogenic, mutagenic or toxic properties linked to their persistence, bio-accumulative nature and physical size. This project proposes to collect, analyse and evaluate the implications of indoor home dust for SVHC to assess the risk to human health. By collaboration as part of the Home Biome project (www.360dustanalysis.com/ and Mapmyenvironment.com), indoor house dust samples will be obtained globally to assess for a range of SVHC including asbestos, flame retardants, PAHs and bisphenols. The project will also assess the human implications and consequences of choice in the indoor home and its subsequent contribution to the occurrence of SVHC. Additional indoor air quality parameters using portable monitors will also be collected. Analysis will be done using analytical instrumentation (GC-MS and microscopy). Extensive data treatment will evaluate the risk to humans (children and adults) using the latest models to estimate potential inhalation and ingestion rates using life cycle analysis. Training and support will additionally include use of relevant analytical instrumentation, sampling techniques, sample preparation and data analysis to undertake complex sample analyses and modelling.
