Modelling Microplastics in the River Thames: Sources, Sinks and Policy Implications
(Peer reviewed; Journal article, 2021)With widespread, long-term historical use of plastics and the presence of microplastics in a range of new and existing products, there is rising concern about their potential impacts on freshwater ecosystems. Understanding ... -
Modelling phosphorus loading and algal blooms in a Nordic agricultural catchment-lake system under changing land-use and climate
(Peer reviewed; Journal article, 2014)A model network comprising climate models, a hydrological model, a catchment-scale model for phosphorus biogeochemistry, and a lake thermodynamics and plankton dynamics model was used to simulate phosphorus loadings, total ... -
Modelling ROS formation in boreal lakes from interactions between dissolved organic matter and absorbed solar photon flux
(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, ... -
Modelling study of soil C, N and pH response to air pollution and climate change using European LTER site observations
(Journal article; Peer reviewed, 2018)Current climate warming is expected to continue in coming decades, whereas high N deposition may stabilize, in contrast to the clear decrease in S deposition. These pressures have distinctive regional patterns and their ... -
Modelling the effects of climate and land-use change on the hydrochemistry and ecology of the River Wye (Wales)
(Journal article; Peer reviewed, 2018)Interactions between climate change and land use change might have substantial effects on aquatic ecosystems, but are still poorly understood. Using the Welsh River Wye as a case study, we linked models of water quality ... -
Modelling the influence from biota and organic matter on the transport dynamics of microplastics in the water column and bottom sediments in the Oslo fjord
(Peer reviewed; Journal article, 2021)The fate of microplastics (MP) in seawater is heavily influenced by the biota: the density of MP particles can be changed due to biofouling, which affects sinking, or MP can be digested by zooplankton and transferred into ... -
Modes of action and adverse effects of gamma radiation in an aquatic macrophyte Lemna minor
(Journal article; Peer reviewed, 2019)High dose rates of ionizing radiation have been reported to cause adverse effects such as reduction in reproduction and growth, and damage to protein and lipids in primary producers. However, the relevant effects of ionizing ... -
Modifisering av ANC- og tålegrenseberegninger ved å inkludere sterke organiske syrer
(NIVA-rapport;5030, Research report, 2005)ANC (syrenøytraliserende kapasitet)-verdier i forsurede vannforekomster er korrigert til ANCoaa for å få mer biologisk relevante verdier i forsurede vannforekomster med høyt innhold av humus (organisk karbon; TOC) . Metoden ... -
Molands- og Langangsvassdraget i Aust-Agder - næringsstofftilførsler, vannkvalitet, plankton og fiskebestander
(NIVA-rapport;3647, Research report, 1997)Molands- og Langangsvassdraget er undersøkt i 1994-1996 mht. vannkvalitet, plankton, fiskebestander og næringssalttilførsler. I følge SFTs klassifiseringssystem må vannkvaliteten på de ulike stasjonene i vassdragene ... -
