There is a pressing need for region-specific information on the response of polar species to contaminants. The Protocol on Environmental Protection to the Antarctic Treaty states “…regular and effective monitoring shall take place to allow assessment of the impacts of ongoing activities, including the verification of predicted impact…”. Although the Treaty only applies to the Antarctic, similar requirements exist for the Arctic; thus, our comments below apply to both polar regions. Without ecotoxicological information all the effort that is directed towards contaminants monitoring is largely meaningless as it does not tell us whether the levels detected pose an environmental risk.
