Biodegradation, Bioaccumulation and Toxicity of Oil Spill Herding Agents in Arctic Waters as Part of an Ecotoxicological Screening
Oil spills from ship traffic or oil production represent a huge threat to the environment. A controlled and thick oil slick is crucial in relation to combatting oil spills, not least for Arctic waters, before introducing the oil spill response method in situ burning. Recently, herding agents have be...

Oil spills from ship traffic or oil production represent a huge threat to the environment. A controlled and thick oil slick is crucial in relation to combatting oil spills, not least for Arctic waters, before introducing the oil spill response method in situ burning.

In this study, we evaluated potential environmental impacts of using herding agents. Toxicity, bioaccumulation and biodegradability of the two herders ThickSlick 6535 (TS6535) and Siltech OP-40 (OP-40) were studied in laboratory set-ups with Arctic water and the high Arctic copepod, Calanus hyperboreus.
