Scientists evaluated two oil risk assessment protocols that use passive dosing to create oil and water accommodated fractions (WAFs) for laboratory tests as potential alternatives to the traditional oil dosing method that CROSERF (multi-agency/organization oil spill research group) recommends.
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.
Scientists conducted laboratory exposure experiments to assess the effects of dispersed crude oil, Corexit 9500A dispersant, and natural ultraviolet B (UVB) radiation on early larval stages of planktonic copepods (“nauplii”).
Crude oil toxicity continued to sicken a sentinel Gulf Coast fish species for at least more than a year after the Deepwater Horizon oil spill in the Gulf of Mexico
