It has recently been shown that the presence of carbonaceous geosorbents (CG, including black carbon (BC), unburned coal, and kerogen) can cause strong sorption polycyclic aromatic hydrocarbons (PAHs) in sediments. We studied native PAHs four Norwegian harbor sediments which high fractions (21-56%) total organic (TOC) consisted CG (CGC), as by petrography. PAH coefficients were 1-2 orders magnitude above predictions based on amorphous partitioning alone. In recent studies, such was...
In situ amendment of contaminated sediments using activated carbon (AC) is a recent remediation technique, where the strong sorption contaminants to added AC reduces their release from and uptake into organisms. The current study describes marine underwater field pilot in Trondheim harbor, Norway, which powdered alone or combination with sand clay was tested as thin-layer capping material for polycyclic aromatic hydrocarbon (PAH)-contaminated sediment. Several novel elements were included,...
Living Labs are recognized as a progressive form to foster innovation and the strengthening of collaborative planning. The concept has received strong attention by European Union (EU) research agendas recently. This contribution investigates how Lab approach could be used for design implementation Nature-Based Solutions (NBS). NBS gaining acceptance more sustainable solution reducing exposure natural hazards vulnerability events, such increased flooding in changing climate. However, lack...
Nature-based solutions (NBS) are inspired and supported by nature but designed humans. Historically, governmental stakeholders have aimed to control using a top-down approach; more recently, environmental governance has shifted collaborative planning. Polycentric co-creation procedures, which include large spectrum of stakeholders, assumed be effective in the management public goods than traditional approaches. In this context, NBS projects should benefit from strong models, European Union...
Abstract The use of vegetation as a Nature-based Solution (NbS) for shallow landslide risk reduction is receiving increased attention in the scientific community. Vegetation can contribute to slope stability through both hydrological and mechanical processes. Slope models are valuable tools quantify performance management stabilizing measure. aim this study provide comprehensive overview how effects parametrized existing models. To end, systematic review peer-reviewed literature published...
Vertical pore water profiles of in situ PCBs were determined a contaminated mudflat San Francisco Bay, CA, 30 months after treatment using an activated carbon amendment the upper layer sediment. Pore concentrations derived from measured two passive samplers; polyethylene (PE, 51 μm thick) and polyoxymethylene (POM, 17 at different sediment depths. To calculate PCB contents samplers, equilibrium approach first-order uptake model applied, five performance reference compounds to estimate...
Nature-based solutions (NBS) are becoming increasingly important in both the EU and individual countries’ political agendas, as a sustainable means to reduce risk posed by hydrometeorological hazards. However, use of NBS is increasing, number barriers regarding their practical implementation also become apparent. A review studies have summarized classified barriers, mainly urban settings. PHUSICOS Horizon 2020 Innovation Action demonstrate rural mountain landscapes. Large-scale demonstrator...
The present paper describes a study on the bioaccumulation of native polycyclic aromatic hydrocarbons (PAHs) from three harbors in Norway using polychaete Nereis diversicolor and gastropod Hinia reticulata. First, biota-sediment accumulation factors (BSAFs) were measured laboratory bioassays original sediments. Median BSAFs 0.004 to 0.01 kg organic carbon/kg lipid (10 PAHs 6 organism-sediment combinations), which was factor 89 240 below theoretical BSAF based total sediment contents (which...
Activated carbon (AC) amendment to polluted sediment or soil is an emerging in situ treatment technique that reduces freely dissolved porewater concentrations and subsequently the ecological human health risk of hydrophobic organic compounds (HOCs). An important question capacity amended AC after prolonged exposure field. To address this issue, sorption freshly spiked native HOCs aged under natural field conditions fresh amendments was compared for one two sediments. After 12-32 months...
A large-scale field experiment on in situ thin-layer capping was carried out the polychlorinated dibenzodioxin and dibenzofuran (PCDD/F) contaminated Grenlandsfjords, Norway. The main focus of trial to test effectiveness active caps (targeted thickness 2.5 cm) consisting powdered activated carbon (AC) mixed into locally dredged clean clay. Nonactive (targed 5 clay without AC as well crushed limestone were also tested. Fields with areas 10,000 40,000 m(2) established at 30 100 m water depth....
This work presents the results of an international interlaboratory comparison on ex situ passive sampling in sediments. The main objectives were to map state science passively sediments, identify sources variability, provide recommendations and practical guidance for standardized sampling, advance use regulatory decision making by increasing confidence technique. study was performed a consortium 11 laboratories included experiments with 14 formats 3 sediments 25 target chemicals (PAHs PCBs)....
This paper explores how claims for transformative adaptation toward more equitable and sustainable societies can be assessed. We build on a theoretical framework describing as it manifests across four core elements of the public-sector lifecycle: vision, planning, institutional frameworks, interventions. For each element, we identify characteristics that help track transformative. Our purpose is to governance systems constrain or support choices thus enable targeted demonstrate test...

Planners and engineers increasingly discovered nature as a source of inspiration to mitigate hydro-meteorological risks resulting from extreme weather events. Actors are realizing advantages such solutions known Nature-Based Solutions (NBS) rapidly adapt changing climate patterns related impacts flooding, landslides, mudflows or rockfalls. NBS also provide multiple co-benefits an increased landscape value for society biodiversity. Because their inherent characteristics, implementation more...
Abstract Field‐related influences on polychlorinated biphenyl (PCB) exposure were evaluated by employing caged deposit‐feeders, Neanthes arenaceodentata, along with polyoxymethylene (POM) samplers using parallel in situ and ex bioassays homogenized untreated or activated carbon (AC) amended sediment. The AC amendment achieved a remedial efficiency reducing bioaccumulation 90% the laboratory 44% field transplants. In measurements showed that PCB uptake POM was greater for placed surface...

Polar organic chemical integrative samplers (POCIS) have previously been used to monitor alkylphenol (AP) contamination in water and produced water. However, only the sorbent receiving phase of POCIS (Oasis beads) is traditionally analyzed, thus limiting use for monitoring a range APs with varying hydrophobicity. Here "pharmaceutical" was calibrated laboratory using static renewal setup (from 2-ethylphenol 4-n-nonylphenol) hydrophobicity (log Kow between 2.47 5.76). The sampler over its 28...
The term nature-based solutions (NBS) has gained traction in recent years and been applied many settings. There are few comprehensive assessment frameworks available that can guide NBS planning implementation while at the same time capturing short- long-term impacts benefits of NBS. Here a recently presented framework, which builds on theory change was developed to assess different phases project cycle, seven diverse case studies. studies addressed water quality quantity issues peri-urban...
Abstract The desorption behavior of phenanthrene, pyrene, and benzo[ a ]pyrene was investigated for three Norwegian harbor sediments their respective particle size fractions using the Tenax method. Rate constants rapidly, slowly, very slowly desorbing were on order 10 −1 , −2 to −4 −6 /h, respectively. Relatively small amounts present in rapidly ( F rapid : <6% 3–19% 1–12% ]pyrene). With exception ]pyrene, these values generally lower than median obtained from more 100 literature native...
Contaminant levels in urban harbor sediments vary with contaminant emission levels, sedimentation rates, and sediment resuspension processes such as propeller wash. Levels of polycyclic aromatic hydrocarbons (PAHs) polychlorinated biphenyls (PCBs) are decreasing many harbors, heavily contaminated that accumulated during past decades being buried by less-contaminated sediments. However, PAHs PCBs remain a concern areas where burial is slow or re-expose older layers. Chronostratigraphic core...
