An Investigation Into Dust, Gases And Vapours Expulsed During The Oxidation Of Pyritic Black Shale, And Their Potential For Impacting On Employee Health, Tristan Lynn
Theses: Doctorates and Masters
Pyritic black shale (PBS) is occasionally extracted as a waste product of iron ore mining in the Pilbara region of Western Australia. Mineralogical studies such as Brocks, Summons, Buick, and Logan (2003) of the PBS located at Mount Tom Price Operations have established that PBS can contain elevated concentrations of pyrite, carbon, bitumens, polyaromatic hydrocarbons and volatile organic compounds (VOCs). The natural oxidative weathering of PBS can cause exothermic reactions leading to the shale reaching temperatures that cause the expulsion of toxic gases such as hydrogen sulphide, sulphur dioxide, methane and carbon monoxide.
Current management of the potential hazards of …

Homebirth In Wa: Why Women Make This Choice, Colleen Ball
Theses: Doctorates and Masters
Background: Homebirths in Western Australia (WA) account for approximately 0.8% of all births. Two consecutive reports from the Perinatal and Infant Mortality Monitoring Committee found increased rates of perinatal mortality in homebirths and recommended a prospective cohort study to assess mortality and morbidity outcomes for women with planned home births in WA. The Homebirth in WA Study, of which this thesis is a component, has been funded by a directed research grant.
Aim: The aim of this study was to explore the specific reasons why women in WA choose homebirth. Research on homebirths is focused on perinatal outcomes and …
