Public Health Implications Of Metal Ash Concentrations From Prescribed Burns: A Study Of Open Jarrah Forests, John Edwards

Theses: Doctorates and Masters

Ash is not a homogenous product. It is the solid residue of combustion and contains a complex mixture of chemical products. The fire that produces ash is non-discriminatory in that it will burn anything that is combustible. The ash residue resulting from fires varies and is dependent on its source, and burn characteristics such as the temperature of the fire. Ash comprises particles of carbon, soot and trace elements.

Evaluation Of A Mosquito Control Intervention And Recommendations For Development Of Best Practice Protocols By The Shire Of Kalamunda, Kerry Staples

Theses: Doctorates and Masters

Abstract

The mosquito control program implemented by the Shire of Kalamunda Environmental Health Service has been assessed. Mosquito species and abundance has been evaluated along with an assessment on the current level of pesticide resistance and downstream S‐methoprene levels post‐treatment. The rate of Ross River virus transmission within the Shire has also been considered, along with the relationship between local species and virus transmission.

Methodology

Floating Emergence Traps were used in 15 storm‐water gullies to determine the effectiveness of S‐methoprene briquets in prevention of adult mosquito emergence over 124 days. Samples were taken monthly from October 2014 to March 2015. …
