Particulate matter (PM) is a pollutant of international and national concern with many studies reporting adverse health effects associated with different size fractions. We regulate based on the size of particles, but the physical and chemical composition of the particles may be as important to adverse health effect as the inhalable size fractions. There is no known threshold for exposure to PM and studies are showing that chemical components may be more important drivers of effects. Different sources have different PM characteristics and indicator compounds, yet this is rarely considered when undertaking risk assessments.
This conference will address characterising particulate matter based on size and composition, the application of in vitro toxicity methods, the emerging health and toxicology studies focussing on composition and how we undertake risk assessments that include multiple sources, estimation of doses and exposures.
The 11th ACTRA Annual Scientific Meeting will be held Thursday 27 September and Friday 28 September 2018 in Perth. A one day Continuing Education Course will precede the ASM on Wednesday 26 September 2018.
