Use of models for the environmental risk assessment of veterinary medicines in European aquaculture: current situation and future perspectives
(Journal article; Peer reviewed, 2019)Veterinary Medicinal Products (VMPs) are used in intensive aquaculture production to treat a wide range of bacterial and parasitic infestations. Their release into the environment poses concerns regarding their potential ... -
Using a Bayesian Network Model to Predict Risk of Pesticides on Aquatic Community Endpoints in a Rice Field—A Southern European Case Study
(Peer reviewed; Journal article, 2023)Bayesian network (BN) models are increasingly used as tools to support probabilistic environmental risk assessments (ERAs), because they can better account for uncertainty compared with the simpler approaches commonly used ... -
Using a chain of models to predict health and environmental impacts in Norway from a hypothetical nuclear accident at the Sellafield site
(Peer reviewed; Journal article, 2020)When a nuclear accident occurs, decision makers in the affected country/countries would need to act promptly to protect people, the environment and societal interests from harmful impacts of radioactive fallout. The decisions ... -
Using Bayesian hierarchical modelling to capture cyanobacteria dynamics in Northern European lakes
(Peer reviewed; Journal article, 2020)Cyanobacteria blooms in lakes and reservoirs currently threaten water security and affect the ecosystem services provided by these freshwater ecosystems, such as drinking water and recreational use. Climate change is ... -
Using biomarkers in wastewater to monitor community drug use: A conceptual approach for dealing with new psychoactive substances
(Journal article; Peer reviewed, 2014)Data obtained from the analysis of wastewater from large-scale sewage treatment plants has been successfully applied to study trends in the use of classical illicit drugs such as cocaine, but the dynamic nature of the new ... -
Using carbon dioxide gas to lower the pH of tunnelling waste water – laboratory test and assessment of toxic potential
(NIVA-rapport;6634, Research report, 2014)Building of tunnels produces waste water that often is highly alkaline. Such water can be toxic to aquatic organisms, and pH should be lowered before discharge to recipient. A reactor tank was built to test the use carbon ... -
Using ecosystem models to inform ecosystem-based fisheries management in Europe: a review of the policy landscape and related stakeholder needs
(Peer reviewed; Journal article, 2023)The need to implement an ecosystem-based fisheries management (EBFM) is enshrined in numerous regulations and strategies, at both global and European level. In practice, it is challenging to implement EBFM because it ... -
Using environmental monitoring data from apex predators for chemicals management: towards better use of monitoring data from apex predators in support of prioritisation and risk assessment of chemicals in Europe
(Peer reviewed; Journal article, 2022)A large number of apex predator samples are available in European research collections, environmental specimen banks and natural history museums that could be used in chemical monitoring and regulation. Apex predators ... -
Using Food Webs and Metabolic Theory to Monitor, Model, and Manage Atlantic Salmon—A Keystone Species Under Threat
(Peer reviewed; Journal article, 2021)Populations of Atlantic salmon are crashing across most of its natural range: understanding the underlying causes and predicting these collapses in time to intervene effectively are urgent ecological and socioeconomic ... -
Using in situ sensor-based monitoring to study impacts of climate change on river water quality and element fluxes
(NIVA-rapport;7812-2023, Research report, 2022)The report contains an analysis of high-frequency sensor data from two rivers included in the Norwegian River Monitoring Programme; Storelva in southern Norway and Målselva in northern Norway. The main aim of the report ... -
Using mussel as a global bioindicator of coastal microplastic pollution
(Journal article; Peer reviewed, 2019)The ubiquity and high bioavailability of microplastics have an unknown risk on the marine environment. Biomonitoring should be used to investigate biotic impacts of microplastic exposure. While many studies have used mussels ... -
Using Passive Samplers to Track per and Polyfluoroalkyl Substances (PFAS) Emissions From the Paper Industry: Laboratory Calibration and Field Verification
(Peer reviewed; Journal article, 2021)Per and polyfluoroalkyl substances (PFAS) are becoming more stringently regulated and as such, a more diverse suite of environmental monitoring methods is needed. In this work a polar organic chemical integrative sampler ... -
