Australia, like many countries, has adopted sediment quality guidelines, which govern construction, waste disposal, dredging, protection of living resources and remediation in coastal regions. Recent studies by the current applicants indicate that these guidelines overestimate sediment toxicity, which may result in unnecessary, costly environmental investigations and possibly needless, very expensive remediation. Although contaminants are in extremely high concentrations in many Australian coastal areas, they may not be available (bioavailable) to benthic animals. A new technique is proposed to determine contaminant bioavalibility and improve the predictability of these guidelines and ensure the ecological sustainable development of coastal environments.

与许多国家一样，澳大利亚也采用了沉积物质量指南，用于管理沿海地区的建筑、废物处理、疏浚、生物资源保护和修复。当前申请人最近的研究表明，这些指南高估了沉积物的毒性，这可能导致不必要的、昂贵的环境调查以及可能不必要的、非常昂贵的修复。尽管澳大利亚许多沿海地区的污染物浓度极高，但底栖动物可能无法利用（生物可利用）这些污染物。提出了一种新技术来确定污染物的生物有效性并提高这些准则的可预测性并确保沿海环境的生态可持续发展。
