Oil Sands Dilbit Causes Developmental Problems in Fish

Scientists have very little idea what the environmental effects of an oil sands “dilbit” spill would be.

The oil that flows in pipes away from Canada’s oil sands is not the same as conventional crude oil. Known as diluted bitumen, or “dilbit,” this proprietary blend of oil and chemicals behaves differently in the event of a spill. Or, scientists suspect it does. So little research has been done on the environmental and ecological effects of dilbit that it’s hard to say for sure. As a first step toward understanding the risks posed by dilbit, scientists working with Alberta oil sands dilbit found that the tacky mixture can cause a range of serious toxic effects in fishRead more in Hakai.
