Exposure and sensitivity of marine turtles and dugongs to dioxins - a risk assessment in near shore marine environments of Queensland

点击翻译按钮获取中文摘要

The World Heritage Great Barrier Reef sustains unique marine biota such as dugongs and turtles. High concentrations of harmful dioxins have been reported recently in dugongs. However, the impacts of these contaminants on the health of dugong and turtle populations remain unknown. This study will redress the general lack of toxicological information available for reptiles and dugongs. This includes assessments of exposure, pathways as well as toxicological responses to the compounds of concern, to provide a robust assessment of the risks associated. The outcomes will guide management policy designed to protect the environmental health of Queensland's Marine Parks.
