About the Project
Fine dust particles are capable of penetrating deep into the lung and can contain a variety of harmful agents, including metals/metalloids, organic substances, microbes and other allergens. Their ultra-fine nature means that they may also migrate into the blood stream causing systemic adverse human health effects. Given that (a) communities are becoming more urbanised and (b) people spend up to 90% of their time indoors it is critically important that we are able to characterise potential exposures to such environmental agents so that a more complete understanding of the human health risks can be developed.
The successful candidate will have the opportunity to be part of a new global network of participating institutions to investigate human exposure to potentially harmful contaminants in household dust collected via a citizen participation platform across three continents (Australia, Europe and North America; http://www.360dustanalysis.com). The PhD research project will include the characterisation of selected key components of indoor vaccum dusts (e.g. metals/metalloids; microbiome; black carbon). ‘Citizen scientists’ will be invited to submit their vacuum dust to the program for analysis, along with data about the home environment (metadata). A range of analytical instrumentation (e.g. XRF, ICP-OES, SEM) and methods (e.g. microbiome sequencing, bioaccessibility, GIS) can be utilised in the study and the data will inform home exposure studies.
Applicants will need good analytical skills and an ability to communicate to a high standard, including with the public, and to other scientists and regulators. Data from the project will contribute to an international resource and databank developed in collaboration with the DustSafe global network of institutions.
The DustSafe network provides a cotutelle option should the successful candidate be interested in exploring this additional opportunity.
