Quantification of an Adverse Outcome Pathway Network by Bayesian Regression and Bayesian Network Modeling
(Peer reviewed; Journal article, 2020)The adverse outcome pathway (AOP) framework has gained international recognition as a systematic approach linking mechanistic processes to toxicity endpoints. Nevertheless, successful implementation into risk assessments ... -
Quantification of Riverbank Macroplastic Contamination in The Lower Citarum River
(Peer reviewed; Journal article, 2022)Plastic waste generation has been increasing over the last decades. Rivers represent complex environments where plastics may be stored and remobilized. Studies on riverine plastic, including riverbank contamination, are ... -
Quantification of the environmental impact of lumpfish farming through a life cycle assessment
(Peer reviewed; Journal article, 2021)Infestations by the salmon louse (Lepeophtheirus salmonis Krøyer) represents the major fish health problem that the Atlantic salmon (Salmo salar) industry has to face. Sea lice infestation has a large impact on the economy ... -
Quantifying ecological and social drivers of ecological surprise
(Journal article; Peer reviewed, 2018)1.A key challenge facing ecologists and ecosystem managers is understanding what drives unexpected shifts in ecosystems and limits the effectiveness of human interventions. Research that integrates and analyses data from ... -
The Quantitative Analysis of Water Mass during Winter on the East China Sea Shelf Using an Extended OMP Analysis
(Peer reviewed; Journal article, 2022)The distribution and quantification of water masses on the East China Sea (ECS) shelf is important for identifying and understanding historical climate-driven changes in ocean properties and circulation in the region. We ... -
Quantitative assessment of visual microscopy as a tool for microplastic research: Recommendations for improving methods and reporting
(Peer reviewed; Journal article, 2022)Microscopy is often the first step in microplastic analysis and is generally followed by spectroscopy to confirm material type. The value of microscopy lies in its ability to provide count, size, color, and morphological ... -
Quantitative fatty acid signature analysis reveals a high level of dietary specialization in killer whales across the North Atlantic
(Peer reviewed; Journal article, 2023)1. Quantifying the diet composition of apex marine predators such as killer whales (Orcinus orca) is critical to assessing their food web impacts. Yet, with few excep- tions, the feeding ecology of these apex predators ... -
Radiation Adverse Outcome pathways (AOPs): examining priority questions from an international horizon-style exercise
(Peer reviewed; Journal article, 2024)Purpose: The Organisation for Economic Co-operation and Development (OECD) Adverse Outcome Pathway (AOP) Development Programme is being explored in the radiation field, as an overarching framework to identify and prioritize ... -
Radiation effects and ecological processes in a freshwater microcosm
(Peer reviewed; Journal article, 2019)Ecosystem response to gamma radiation exposure depends on the different species sensitivities and the multitude of direct and indirect pathways by which individual organisms can be affected, including the potential for ... -
RADIBIO. Degradation of recalcitrant chlorinated organics by combination of radiochemical and biochemical oxydation
(NIVA-rapport;2781, Research report, 1992)The method have been tested for degrading chlorogranics (AOX) in kraft bleach effluents with a removal efficiency of aproximately 75%. With optimization, a theoretical outline indicates that is should be possible to remove ... -
