“…PBDE congener profiles in sediments are dominated by higher brominated congeners such as BDE-209 and DBDPE. This is different from profiles in biota samples, which are dominated by lower brominated congeners, such as BDE-47 and BDE-99 [34]. In marine sediments, BFRs were detected in Canada [35], San Francisco Bay, USA [36], Gulf of Lion, France [37], Northern Arabian Gulf [38], East Java Province, Indonesia [39], Goseong Bay, Korea [40], South China [41], and the Scheldt estuary, the Netherlands [42].…”

Polybrominated diphenyl ethers (PBDEs) and 'novel' brominated flame retardants (NBFRs) are synthetic chemicals widely used in consumer products to enhance their ignition resistance. Since in most applications, these chemicals are used additively, they can transfer from such products into the environment. PBDEs have been classified as significant pollutants in the environment. Knowledge of PBDE and NBFR physicochemical properties provides information about their potential environmental fate and behaviour. This chapter highlights the most important physiochemical properties such as molecular weight, vapour pressure, octanol/air partitioning coefficient, octanol/water partition coefficient, water solubility and organic carbon/water partitioning coefficient that influence the distribution pattern of these contaminants in the environment. In addition, this chapter provides an evaluation of the concentrations of these chemicals in various environmental media such as indoor and outdoor air, indoor dust, soil and sediment, sewage sludge, biota and food, and human tissues.

Piet, G.J 1 ., Boon, A 2 . Jongbloed, R 1 ., van der Meulen, M 2 ., Tamis, J 1 . van der Wal, J.T 1 .Teal ,L SummaryThis development of the framework and approach for a Cumulative Effects Assessment (CEA) is based on a literature review. From this we adopted several definitions that guided this development.• A CEA is understood as "a systematic procedure for identifying and evaluating the significance of effects from multiple sources/activities and for providing an estimate on the overall expected impact to inform management measures. The analysis of the causes (source of pressures and effects), pathways and consequences of these effects on receptors is an essential and integral part of the process".• Cumulative effects are "the incremental impact of the action when added to the other past, present and reasonably foreseeable actions". In this approach we only consider a (cumulative) effect significant if it has an impact on a relevant ecosystem component.Therefore our framework and approach for a CEA is based on all human activities that may have a potential impact on any relevant (from a policy perspective) ecosystem component at an appropriate spatio-temporal scale.The literature also identified some key challenges that need to be addressed for CEA to evolve into a consistent, appropriate tool to assist decision-making. These challenges included• A clear distinction of the receptor-led CEA from the dominating stressor-led Environmental Impact Assessment (EIA) approaches and• Enabling CEA to provide ecosystem-relevant information at an appropriate regional scale.Therefore this CEA is explicitly developed to be a receptor-led and fully integrated framework, i.e.involving multiple occurrences of multiple pressures (from single and/or different sources) on multiple receptors, as opposed to other existing approaches dealing with only a subset of those pressures or receptors, hence our use of the phrase iCEA for integrated CEA. As a proof of concept for this iCEA we selected one receptor, the ecosystem component marine mammals.From the literature review we adopted (and slightly modified) a risk-based framework for defining and undertaking cumulative effects assessments which is aligned to the work in the OSPAR IntersessionalCorrespondence Group on Cumulative (ICG-C) Effects and the ICES Working Group on IntegratedAssessments of the North Sea (WGINOSE), thereby ascertaining this framework and approach is wellplaced within ongoing international North Sea initiatives. Furthermore, the CEA framework in this study should contribute to national North Sea policymaking, with a specific focus on the Marine Strategy framework Directive (MSFD). This literature review is presented in Chapter 1.Our iCEA framework consists of four phases each corresponding to a chapter in this report:1. Conception. This is where purpose and scope are defined (see Chapter 2). 3. Execution (importance). Here we establish the relative importance of each impact chain using a risk-based approach that calculates "Impact Risk", i.e. the contribution of...

“…As a "sink" for almost all types of pollutants, marine environment is the ultimate gathering place of PBDEs, which have been detected in seawater, sediments, and marine organisms (Jiang et al, 2019). And it was reported that PBDEs were several orders of magnitude higher in organisms than that in water because of their lipophilicity (Lee and Kim, 2015). Recently, a number of studies have focused on the in uence and toxicity of PBDEs on marine organisms at physiological, biochemical, and molecular levels.…”

In this work, Phaeodactylum tricornutum was used to investigate the toxicity of 4,4'-dibromodiphenyl ether (BDE-15). Results showed that BDE-15 inhibited the photosynthetic activity and growth of P. tricornutum significantly with 24, 48, 72, and 96 h EC50 values of 1.03, 0.44, 0.41, and 0.42 mg L-1, respectively, indicating that it was a highly toxic substance. Moreover, BDE-15 could cause cell deformation, and a series of physiological, biochemical, and molecular changes in the cells. Under the exposure of BDE-15, contents of chlorophyll a and soluble protein decreased significantly, but reactive oxygen species (ROS) were accumulated in the algal cells, which may cause or intensify the peroxidation of membrane lipids. For alleviating the toxicity of excessive ROS, activities of antioxidant enzymes increased dramatically when this diatom was exposed to BDE-15. Thus, it is concluded that the overproduction of ROS may be regarded as one of the major factors in BDE-15 toxicity.
