Sensitivity of the deep-sea amphipod Eurythenes gryllus to chemically dispersed oil

摘要: In the context of an oil spill accident and following response, much attention is given to use dispersants. Dispersants are used disperse slick from sea surface into water column generating a cloud dispersed droplets. The main consequence increasing water-oil interface which induces increase biodegradation. Hence, dispersants can be effective in preventing oiling sensitive coastal environments. Also, case blowout seabed, subsea injection may offer some benefits compared containment recovery or situ burning operation at surface. However, biological effects poorly understood for deep-sea species. Most studies on also other oil-related compounds have been focusing more shallow This first approach assess sensitivity macro-benthic organism oil. paper describes toxicity test was performed amphipod (Eurythenes gryllus) determine concentration causing lethality 50% individuals (LC50) after exposure Brut Arabian Light (BAL) LC50 (24 h) 101 24 mg L(-1) 72 h 12 96 h.

Due limited amount data available amphipods, information crustacean species collected. Only one amphipods found, value this similar gryllus study. Since important input risk assessment net environmental benefit analyses, since such generally lacking species, set produced interest industry, stakeholders, management, ecotoxicologists. including covering different functional groups needed evaluate compartments relative compartments.
