(NIVA-rapport;7284, Research report, 2018)Kristiansand kommune tok i 2016 initiativ til å få utarbeidet et forurensningsregnskap for deler av Kristiansandsfjorden. Det var et mål å skaffe mer kunnskap om alle relevante forurensningskilder og forurensningsbidraget ... -
Urbanhydrologi i Sverige. Litteraturstudie om forskningsresultater. VA-26/83
(NIVA-rapport;1561, Research report, 1983)I Sverige er det satset relativt mye på forskning om urban hydrologi. Rapporten refererer de mest interessante resultater av denne forskningen på delfeltene korttidsnedbør, overvannsavrenning og snøsmelting. For de enkelte ... -
Use of High Throughput Sequencing and Light Microscopy Show Contrasting Results in a Study of Phytoplankton Occurrence in a Freshwater Environment
(Journal article; Peer reviewed, 2014)Assessing phytoplankton diversity is of primary importance for both basic and applied ecological studies. Following the advances in molecular methods, phytoplankton studies are switching from using classical microscopy to ... -
Use of macroinvertebrates to classify water quality. Report No 2 A: Acidification
(NIVA-rapport;3338, Research report, 1995)Norwegian watercourses are becoming increasingly acidified. Small animals on the river bottom can be used to classify the biological damage caused by acidification, The report describes the classification systems developed ... -
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 belief networks in pollution abatement planning. Example from Morsa catrchment, South Eastern Norway
(NIVA-rapport;5213, Research report, 2006)A Bayesian belief network approach is used to conduct decision analysis under uncertainty of nutrient abatement measures in the Morsa catchment, South Eastern Norway, structuring available cost-effectiveness studies, ... -
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 ... -
