Oil spills spell disaster for affected wildlife, leading to detrimental outcomes, including suffocation, poisoning and problems related to exposure to crude oil and its components. Researchers now take a closer look at the potential effects on regional salmon populations as Canada eyes expansion of its crude oil export capacity.
Oil spills and industrial discharge can contaminate water with greasy substances. Although it’s true that oil and water don’t mix, separating and recovering each component can still be challenging. Now, researchers have created sponges made from wood that selectively absorb oil, and then can be squeezed out and used again.
