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

世界遗产大堡礁维持着独特的海洋生物，如儒艮和海龟。最近有报道称儒艮体内含有高浓度的有害二恶英。然而，这些污染物对儒艮和海龟种群健康的影响尚不清楚。这项研究将弥补爬行动物和儒艮毒理学资料普遍缺乏的问题。这包括对所关注化合物的暴露、途径和毒理学反应进行评估，以便对相关风险进行可靠的评估。研究结果将指导旨在保护昆士兰海洋公园环境健康的管理政策。

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.
