Oil contains thousands of different compounds that each affect the environment and living organisms differently. While some compounds have been well-studied, there are exponentially more that have not.
Data and pictures from before and after a disaster help us understand the impacts of an event; however, the “before” is not always available. Researchers with the RECOVER consortium have found through oil-exposure laboratory studies that the Deepwater Horizon incident may have negatively affected mahi-mahi’s heart function, vision, and swim performance.
Researchers conducted laboratory experiments on mahi-mahi embryos to determine the effects of ultraviolet radiation (UV) and oil co-exposure during different times in their development. The team observed that UV affected the success of mahi-mahi hatch in all exposure scenarios compared to controls but was highest (a 1.6- to 6-fold increase) when co-exposure occurred late in embryonic development.
