The role of microbial exopolymers in determining the fate of oil and chemical dispersants in the ocean

Limnology and Oceanography Letters, 2016
The production of extracellular polymeric substances (EPS) by planktonic microbes can influence the fate of oil and chemical dispersants in the ocean through emulsification, degradation, dispersion, aggregation, and/or sedimentation.

Effects of chemical dispersants on feathers from Arctic seabirds [PDF]

, 2023
Chemical dispersion is an oil spill response strategy where dispersants are sprayed onto the oil slick to enhance oil dispersion into the water. However, accidental application could expose seabirds to dispersants, thereby negatively affecting their ...
