    • A Bayesian Approach to Incorporating Spatiotemporal Variation and Uncertainty Limits into Modeling of Predicted Environmental Concentrations from Chemical Monitoring Campaigns 

      Wolf, Raoul; Tollefsen, Knut-Erik (Peer reviewed; Journal article, 2021)
      Environmental monitoring studies provide key information to assess ecosystem health. Results of chemical monitoring campaigns can be used to identify the exposure scenarios of regulatory concern. In environmental risk ...

    • Development of a hybrid Bayesian network model for predicting acute fish toxicity using multiple lines of evidence 

      Moe, Jannicke; Madsen, Anders; Connors, Kristin; Rawlings, Jane; Belanger, Scott; Landis, Wayne; Wolf, Raoul; Lillicrap, Adam David (Peer reviewed; Journal article, 2020)
      A hybrid Bayesian network (BN) was developed for predicting the acute toxicity of chemicals to fish, using data from fish embryo toxicity (FET) testing in combination with other information. This model can support the use ...

    • Evaluation of a Bayesian network for strengthening the weight of evidence to predict acute fish toxicity from fish embryo toxicity data 

      Lillicrap, Adam David; Moe, Jannicke; Wolf, Raoul; Connors, Kristin A.; Rawlings, Jane M.; Landis, Wayne G.; Madsen, Anders L.; Belanger, Scott E. (Peer reviewed; Journal article, 2020)
      The use of sh embryo toxicity (FET) data for hazard assessments of chemicals, in place of acute sh toxicity (AFT) data, has long been the goal for many environmental scientists. The FET test was rst proposed as a ...

    • Knowledge graph embedding for ecotoxicological effect prediction 

      Myklebust, Erik Bryhn; Jimenez-Ruiz, Ernesto; Chen, Jiaoyan; Wolf, Raoul; Tollefsen, Knut-Erik (Journal article; Peer reviewed, 2019)
      Exploring the effects of a chemical compound on a species takes a considerable experimental effort. Appropriate methods for estimating and suggesting new effects can dramatically reduce the work needed to be done by a ...

    • Modelling ROS formation in boreal lakes from interactions between dissolved organic matter and absorbed solar photon flux 

      Wolf, Raoul; Thrane, Jan-Erik; Hessen, Dag Olav; Andersen, Tom (Journal article; Peer reviewed, 2018)
      Concentrations of dissolved organic matter (DOM) are increasing in a large number of lakes across the Northern hemisphere. This browning serves a dual role for biota by protecting against harmful ultraviolet radiation, ...

    • Overvåking av Indre Oslofjord i 2013 

      Berge, John Arthur; Amundsen, Rita; Gitmark, Janne Kim; Gundersen, Hege; Haande, Sigrid; Johnsen, Torbjørn Martin; Kroglund, Tone; Ledang, Anna Birgitta; Lømsland, Evy Rigmor; Staalstrøm, Andre; Hylland, Ketil; Holth, Tor Fredrik; Bratrud, Tage; Bølling, Nicolai; Erdahl, Espen; Hinchcliffe, Christopher; Wisbech, Cathrine; Wolf, Raoul (NIVA-Rapport;6697;, Research report, 2014)
      Rapporten gir en kort oversikt over resultatene fra overvåkingen foretatt for Fagrådet for vann- og avløpsteknisk samarbeid i Indre Oslofjord i 2013. En mer utfyllende presentasjon av resultatene er gitt i en vedleggsrapport ...

    • Overvåking av Indre Oslofjord i 2013 - Vedleggsrapport 

      Berge, John A; Amundsen, Rita; Bratrud, Tage; Bølling, Nicolai; Gitmark, Janne Kim; Gundersen, Hege; Hinchcliffe, Christopher; Holth, Tor Fredrik; Haande, Sigrid; Hylland, Ketil; Johnsen, Torbjørn Martin; Kroglund, Tone; Ledang, Anna Birgitta; Norli, Marit; Lømsland, Evy Rigmor; Staalstrøm, Andre; Wisbech, Cathrine; Wolf, Raoul (NIVA-rapport;6698, Research report, 2014)
      Her rapporteres resultatene fra overvåkingen i Indre Oslofjord i 2013. En mindre omfattende beskrivelse av resultatene er gitt i NIVA rapport nr. 6697. Undersøkelsene omfatter fysiske, kjemiske og biologiske forhold. ...

    • Quantification of an Adverse Outcome Pathway Network by Bayesian Regression and Bayesian Network Modeling 

      Moe, S. Jannicke; Wolf, Raoul; Xie, Li; Landis, Wayne G.; Kotamäki, Niina; Tollefsen, Knut-Erik (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 ...

    • Toxicity of microplastics and natural particles in the freshwater dipteran Chironomus riparius: Same same but different? 

      Scherer, Christian; Wolf, Raoul; Völker, Johannes; Stock, Friederike; Brennhold, Nicole; Reifferscheid, Georg; Wagner, Martin (Peer reviewed; Journal article, 2020)
      Microplastics (MP) are contaminants of emerging concern in aquatic ecosystems. While the number of studies is rapidly increasing, a comparison of the toxicity of MP and natural particulate matter is largely missing. In ...

    • UV radiation affects antipredatory defense traits in Daphnia pulex 

      Eshun-Wilson, Franceen; Wolf, Raoul; Andersen, Tom; Hessen, Dag O; Sperfeld, Erik (Peer reviewed; Journal article, 2020)
      In aquatic environments, prey perceive predator threats by chemical cues called kairomones, which can induce changes in their morphology, life histories, and behavior. Predator‐induced defenses have allowed for prey, such ...

    • Weight of evidence tools in the prediction of acute fish toxicity 

      Belanger, Scott E.; Lillicrap, Adam David; Moe, S. Jannicke; Wolf, Raoul; Connors, Kristin; Embry, Michelle R. (Peer reviewed; Journal article, 2022)
      Acute fish toxicity (AFT) is a key endpoint in nearly all regulatory implementations of environmental hazard assessments of chemicals globally. Although it is an early tier assay, the AFT assay is complex and uses many ...
