Detection of macroplastic on beaches using drones and object-based image analysis
(NIVA-rapport;7553, Research report, 2020)This pilot study demonstrates UAV-based image collection being a promising technology for plastic detection in beach zones and we recommend object-based image analysis and UAV-based data collection being further developed ... -
Detection of Transient Denitrification During a High Organic Matter Event in the Black Sea
(Peer reviewed; Journal article, 2019)N2 production by denitrification can occur in anoxic water or potentially inside organic particles. Here we compare data from the Black Sea, a permanently anoxic basin, during two organic matter regimes: suspended particulate ... -
Detection of tris(2,3-dibromopropyl) phosphate and other organophosphorous compounds in Arctic rivers
(Journal article; Peer reviewed, 2018)The flame-retardant tris(2,3-dibromopropyl) phosphate (TDBrPP) was in the 1970s banned for uses in textiles that may be in contact with the skin, owing to strong suspicions that the substance was a human carcinogen. The ... -
Detektion af miljø-DNA med ‘quantitative Polymerase Chain Reaction’ (qPCR) sammenlignet med ‘droplet digital Polymerase Chain Reaction’ (ddPCR)
(NIVA-rapport;7872-2023, Research report, 2023)Detektion af miljø-DNA (engelsk: ‘environmental DNA’, forkortet: ‘eDNA’) kan gøres med blandt andet qPCR og ddPCR, hvor ddPCR ved detektion af DNA fra virus eller bakterier i human patologiske studier er blevet demonstreret ... -
Determining the effects of the discharge effluent from the Karmøy aluminium smelter using an integrated biological effects approach
(NIVA-rapport;7772-2022, Research report, 2022)The report describes a monitoring programme using field transplanted mussels to determine the potential biological effects of the effluent discharge from the Karmøy aluminium smelter operated by Hydro Aluminium in Norway. ... -
Determining the risk of calcium oxide (CaO) particle exposure to marine organisms
(Peer reviewed; Journal article, 2020)Calcium oxide (CaO) is being considered as a possible treatment for both the control of echinoderm populations and the treatment against sea lice infestation in Norwegian salmon farms. CaO particles produce an exothermal ... -
Detoxifying CO2 capture reclaimer waste by anaerobic digestion
(Journal article; Peer reviewed, 2014)The decrease in toxicity of carbon capture reclaimer monoethanolamine (MEA) waste (MEAw) during anaerobic degradation of such waste together with easily degradable organics was investigated. Samples were collected from a ... -
Detrital carbon production and export in high latitude kelp forests
(Peer reviewed; Journal article, 2020)The production and fate of seaweed detritus is a major unknown in the global C-budget. Knowing the quantity of detritus produced, the form it takes (size) and its timing of delivery are key to understanding its role as a ... -
Development and testing of a prototype indicator-based tool for identification of potential problem areas for marine litter in Europe's seas
(Peer reviewed; Journal article, 2023)We demonstrate a prototype multi-metric indicator-based assessment tool (i.e. Marine Litter Assessment Tool - MALT) for mapping and identification of ‘problem areas’ and ‘non-problem areas’ regarding the occurrence of ... -
Development of a Bayesian network for probabilistic risk assessment of pesticides
(Peer reviewed; Journal article, 2021)Conventional environmental risk assessment of chemicals is based on a calculated risk quotient, representing the ratio of exposure to effects of the chemical, in combination with assessment factors to account for uncertainty. ... -
Development of a hybrid Bayesian network model for predicting acute fish toxicity using multiple lines of evidence
(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 ... -
Development of a Norwegian monitoring program for Macroplastic and Litter
(NIVA-rapport;7798-2022, Research report, 2022)The Norwegian Environment Agency (NEA) aims to strengthen environmental monitoring of macroplastic and litter pollution in Norway. Macroplastic and litter are items above 25 mm. Monitoring of litter in the Northern Fulmar ... -
Development of a qPCR assay to detect and quantify ichthyotoxic flagellates along the Norwegian coast, and the first Norwegian record of Fibrocapsa japonica (Raphidophyceae)
(Journal article; Peer reviewed, 2018)Blooms of ichthyotoxic microalgae pose a great challenge to the aquaculture industry world-wide, and there is a need for fast and specific methods for their detection and quantification in monitoring programs. In this ... -
Development of species-specific eDNA-based test systems for monitoring of freshwater crayfish
(NIVA-rapport;7447, Research report, 2019)This MONIS 5 report focuses on freshwater crayfish and was funded by the Danish Environmental Protection Agency. The aim of the present study was to develop species-specific systems for tracking environmental DNA (eDNA) ... -
Development of species-specific eDNA-based test systems for monitoring of non-indigenous Decapoda in Danish marine waters
(NIVA-rapport;7544, Research report, 2020)We report the development of seven eDNA-based species-specific test systems for monitoring of marine Decapoda in Danish marine waters. The seven species are 1) Callinectes sapidus (blå svømmekrabbe), 2) Eriocheir sinensis ... -
DI (density index). Density of marine macroinvertebrates as indicator of environmental status
(NIVA-rapport;6654, Research report, 2014)DI (density index) is a new index for fauna density. DI was specially developed for classifying status of low-density faunas. Indices for diversity and sensitivity in those cases may function poorly, due to accidental fauna ... -
