The report for authorities and scientists provides an overview of substances that can be released into the marine environment from various offshore industries and estimates the quantities of pollutant inputs. These may be relevant as additional contaminants according to European Commission Decision (EU) 2017/848 for Descriptor 8, Criterion D8C1. In addition to the potential hazardous substances from the offshore wind and offshore oil and gas industries, which were published in sub-reports 1 and 2 of the RESOW project, three other offshore sources are considered in this report: Mariculture, maritime transport and (historically) dumped munitions.

The report for industry and permitting authorities provides an overview of the best available techniques to prevent emissions of hazardous substances from the offshore wind industry into the marine environment during installation, operation and decommissioning. In addition to risk management through the use of proper procedures, timely inspection and knowledgeable personnel, the report identifies the technical measures and techniques that are currently available, tested and economically feasible, as well as the current legislative background. The areas covered are technical installation, storage, bunkering, fire protection, corrosion protection, discharges from open systems, antifouling, cleaning and substitution of hazardous substances.

Der vorliegende Bericht dient der Informationssammlung und Zusammenfassung in Bezug auf die Bergung von gefährlicher oder wassergefährdender Ladung aus Schiffswracks aus den zwei vergangenen Weltkriegen. Auf diese Weise soll die Grundlage für die Aufstellung einer Strategie zur systematischen Vorgehensweise bei der Identifizierung und Bergung solcher gefährlichen Ladungen aus Schiffswracks geschaffen werden. Durch weitere Vertiefung und Detaillierung kann in einem Folgeprojekt ein Handlungs- und Leitfaden ausgearbeitet werden, der für Behörden und Bergungsunternehmen verwendbar ist.

Within the RESOW project potential emissions of hazardous substances from the offshore industry into the North Sea and Baltic Sea are investigated. This report gives an overview on potential emissions of hazardous substances from the oil and gas industry, which are associated to the different activities on the offshore platforms. Emissions from drilling fluids, cuttings piles, accidental spills, produced water and corrosion protection materials are investigated. The individual substances are further investigated on their hazardous potential for the aquatic environment. Information from man-made chemicals was only available in a highly aggregated form and no information on individual substances could be retrieved from the aggregated data. Only for produced water information on individual substances could be obtained. The assessment criteria for the determination of hazardous potential is based on PBT criteria, H-phrase related to aquatic toxicity, SIN-list (Substitute It Now), OSPAR list of possible concern, OSPAR list of priority substances, the ECHA list of endocrine disruptive substances and the Water Framework Directive river basin specific pollutants and priority substances respectively listed in annex 6 and 8 of the German Ordinance on the Protection of Surface Waters, which represent the national implementation of the Water Framework Directive.

The report for industry and permitting authorities provides an overview of the hazardous substances that can be released into the marine environment during the installation, operation and decommissioning of offshore wind turbines, including transformer stations, converter platforms and cables. The substances relevant to operation were identified and listed. These substances were assessed for their potential risk to the aquatic environment based on the following criteria: ⁠PBT⁠ criteria, H-phrases for aquatic toxicity, listing on ⁠REACH⁠, ⁠OSPAR⁠, ChemSec and ECHA contaminant lists. Applications in open systems such as galvanic corrosion protection and fire extinguishing foams, but also accidents with fuels and hydraulic oils are possible sources of emissions of hazardous substances into the marine environment.

As stated by HELCOM Expert Group on Marine Mammals (EG MAMA; portal.helcom.fi, 2021), limited information is available on the occurrence, (eco)toxicity, and potential health effects of contaminants of emerging concern (CECs) in marine mammals. CECs are introduced into the environment by various anthropogenic activities andsome of these substances may have the potential to enter marine, freshwater and/or terrestrial food webs, where they can accumulate. Currently, exposure information is often missing and there is an urgent need for sufficient occurrence and effects data to be able to assess CECs and initiate risk mitigation measures where appropriate. The objective of the project was to screen for potentially hazardous CECs in marine mammals from the Baltic Sea using state-of-the-art wide-scope target and suspect screening analytical methodologies. For this purpose, 11 pooled livers and one non-pooled muscle sample from 11marine mammals' samples (Harbour porpoise (Phocoena phocoena), Common dolphin (Delphinus delphis), Grey seal (Halichoerus grypus), Harbor seal (Phoca vitulina)) were provided by HELCOM contracting parties from Germany, Sweden, Denmark and Poland.

Dieser Bericht fasst die wesentlichen Arbeiten der Umweltprobenbank des Bundes im Jahr 2020 zusammen. Die Umweltprobenbank des Bundes unterstützt die Umsetzung des Vorsorgeprinzips mit einer wissenschaftlichen Infrastruktur, einer umfassende Datenbasis zur Bestimmung und Bewertung des Ist-Zustandes der Umwelt und einer langfristigen Beobachtung der in der Umwelt stattfindenden chemischen, physikalischen und biologischen Entwicklungsprozesse. Dafür sammeln Fachleute Humanproben ausgewählter Standorte gemeinsam mit ökologisch repräsentativen Umweltproben, archivieren sie bei tiefkalten Temperaturen und führen Untersuchungen auf gesundheits- und umweltrelevante Stoffe durch. Auf diese Weise wird auch eine Kontrolle der Wirksamkeit umweltpolitischer Maßnahmen möglich, beispielsweise bei Beschränkungen der Verwendung von Stoffen.
