Abstract

Abstract: This study investigated the sensitivity of two deepsea species using mortality of northern shrimp ( Pandalus borealis ) and polyp activity of stony coral ( Lophelia pertusa ) to dispersant, Corexit 9500 and aromatic hydrocarbons (toluene, 2-methylnaphthalene, phenanthrene) in 96-h tests. Resulting hydrocarbon toxicity data were fit to the Target Lipid Model to generate predictive models and determine species sensitivity. Toxicity of chemically enhanced water accommodated fractions of Alaskan North Slope crude oil (ANS-oil) was also investigated with shrimp using nominal loading, total petroleum hydrocarbons and biomimetic extraction (BE) as oil exposure metrics. Coral were more sensitive to dispersant than shrimp while similar sensitivity was observed for hydrocarbons. Study and literature findings indicate deepsea species exhibit acute sensitivities to dispersant, hydrocarbons and oil that are comparable to pelagic species. Results support use of passive sampling methods to quantify dissolved oil for interpreting oil toxicity tests and suggest models for predicting time-dependence of toxicity warrant re-evaluation. Graphical abstract: Unlabelled Image Highlights: Toxicity tests performed on dispersant and hydrocarbons with two deepsea species Coral more than an order of magnitude more sensitive to dispersant than shrimp Sensitivity of both species to hydrocarbons within a factor of two Passive sampling used to quantify dissolved oil exposures in CEWAF test Deepsea species exhibit comparable acute sensitivities to pelagic organisms.
