Past research has shown that mercury associates with offshore oil and gas pipelines as well as other products associated with the infrastructure, deeming such materials “hazardous”. However, the current environmental risk assessments for decommissioning activities of such contaminated materials does not take into account the complexity of the compound's nature and the potential harmful effects on e.g. marine food webs. This review paper has outlined these gaps in our current understanding, as well as providing advice on addressing these gaps to ensure that the marine environmental risk assessments reflect the hazardous nature of mercury-contaminated offshore infrastructure.
