Abstract:

Expanding oil and gas and shipping activities in the absence of sufficient baseline data on the sensitivity of Arctic marine biota to oil related compounds makes environmental risk assessment for the Arctic challenging. Arctic benthic macroinvertebrates can be applied as relevant and sensitive bioindicators of chemicals stress and are important food sources for higher trophic levels. This thesis revised the applicability of exposure assessment methods to oil related compounds in Arctic and temperate species, based on which one Arctic bioindicator species and one potential tool for the assessment of oil impacts on sediment were proposed for their further validation under Arctic conditions. It also underlined the need for standard sediment test protocols and baseline studies as an integral part of environmental risk assessment in the Arctic, and provided several recommendations based on existing guidelines and a comparative study of bioaccumulation data from field and laboratory studies with Arctic species.
