外文摘要：The extraction and processing of Canada's massive oil sands in the Athabasca region of northern Alberta have been marked by an ongoing controversy about the nature and extent of associated environmental impacts. Impacts include habitat destruction and fragmentation by surface mining and tailings disposal, depletion of water resources, greenhouse gas and chemical emissions, and the impacts of emissions on environmental and human health. The debate has been characterized by accusation, denial, emotion, and few reliable or appropriate data to clarify the issues. Thankfully, a pa-leolimnology study in PNAS by Kurek et al. (1) provides some badly needed perspective. They report the distribution of poly-nuclear aromatic hydrocarbons (PAHs) in sediment cores of lakes proximate to oil sands industries and as far as 90 km away.
