项目摘要

We will assess risks associated with a diluted bitumen (dilbit) spill to water, the major environmental risk from pipelines. The purpose of this research is to generate important information on the fate, transport, and toxicity of dilbit to inform management practices and regulatory measures on future pipeline projects. The objectives of this research are: (1) quantify the behavior, fate, and weathering of dilbit constituents in a natural Canadian Boreal water column as simulated in a contained enclosure system; (2) perform an exposure assessment of dilbit constituents based on a 'water column' and 'bottom substrate' exposure design; (3) determine bioaccumulation of dilbit constituents from a water column', and 'bottom substrate' exposure design; (4) assess dilbit toxicity based on a 'dose-response' design; and (5) provide much-needed information to assist the development of management practices and regulations for the transport of diluted bitumen in Canada. This research will provide important information on the long term impacts of dilbit spills in aquatic environments and assist in planning remediation strategies for future spills. This information is critical for local decision makers, including Environment and Climate Change Canada, Fisheries and Oceans Canada, the National Energy Board, and the Ontario Ministry of the Environment, who are responsible for managing lands affected by pipeline breaches.

我们将评估与稀释沥青（稀释沥青）泄漏到水中有关的风险，主要的环境风险来自管道。本研究的目的是产生关于稀释沥青的命运、运输和毒性的重要信息，为未来管道项目的管理实践和监管措施提供信息。本研究的目的是：(1)在封闭的封闭系统中模拟天然加拿大北方水柱中稀释沥青成分的行为、命运和风化；(2)基于“水柱”和“底基质”暴露设计对稀释沥青成分进行暴露评估；(3)确定“水柱”和“底部基质”暴露设计中稀释沥青成分的生物积累；(4)根据“剂量-反应”设计评估稀释沥青毒性；(5)提供急需的信息，以协助制定加拿大稀释沥青运输的管理实践和法规。本研究将为稀释沥青泄漏对水生环境的长期影响提供重要信息，并有助于规划未来泄漏的修复策略。这些信息对当地决策者至关重要，包括加拿大环境和气候变化局、加拿大渔业和海洋局、国家能源局和安大略省环境部，他们负责管理受管道泄漏影响的土地。
