Maternal transfer and occurrence of siloxanes, chlorinated paraffins, metals, PFAS and legacy POPs in herring gulls (Larus argentatus) of different urban influence
(Peer reviewed; Journal article, 2021)Urban herring gulls (Larus argentatus) are exposed to contaminants from aquatic, terrestrial and anthropogenic sources. We aim to assess if differences in urbanisation affect ecological niche and contaminant concentrations ... -
Measurement of naphthenic acids in the receiving waters around an offshore oil platform by passive sampling
(Journal article; Peer reviewed, 2014)Polar organic chemical integrative samplers (POCIS) were deployed in the vicinity of an offshore oil installation and analyzed for naphthenic acids (NAs). The POCIS accumulated a range of mono‐ to tetracyclic NAs, with ... -
Measuring amines in Norwegian surface waters
(NIVA-rapport;6781, Research report, 2015)In summer 2012 we carried out a survey of amine concentrations in 21 Norwegian lakes with the aim of assessing the prevalence of amines in Norwegian lakes and identifying the main factors affecting concentrations of these ... -
Measuring riverine macroplastic: Methods, harmonisation, and quality control
(Peer reviewed; Journal article, 2023)River systems are a key environmental recipient of macroplastic pollution. Understanding the sources of macroplastic to rivers and the mechanisms controlling fate and transport is essential to identify and tailor measures ... -
Mechanical removal of macrophytes in freshwater ecosystems: Implications for ecosystem structure and function
(Peer reviewed; Journal article, 2021)Macrophytes are generally considered a nuisance when they interfere with human activities. To combat perceived nuisance, macrophytes are removed, and considerable resources are spent every year worldwide on this practice. ... -
Mechanisms for metal nodule formation on sediment surfaces of limed lakes
(NIVA-rapport;6875, Research report, 2015)The water chemical and biological effects of liming have been fairly well documented. One of the research projects revealed relatively large (up to 1-3 cm in diameter) metal nodules on the sediment surface of some of the ... -
Membrane bioreactors (MBRs): Activated sludge filterability and full-scale MBR functioning
(Journal article; Peer reviewed, 2013)Despite continuous developments in the field of MBR technology, membrane fouling together with the associated energy demand and related costs issues remain major challenges. The efficiency of the filtration process in an ... -
Membrane bioreactors - A review on recent developments in energy reduction, fouling control, novel configurations, LCA and market prospects
(Journal article; Peer reviewed, 2017)Membrane bioreactor (MBR) technology is considered a well-established, mature technology with many full-scale plants around the world treating municipal and industrial wastewater. However, membrane fouling and energy ... -
Mercury concentration trend as a possible result of changes in cod population demography
(Journal article; Peer reviewed, 2017)Mercury (Hg) in Atlantic cod (Gadus morhua) is one of many parameters that are monitored through OSPAR's Joint Assessment and Monitoring Programme. Time series for cod in the Inner Oslofjord (Norway) go back to 1984. Until ... -
Mercury in air and soil on an urban-rural transect in East Africa
(Peer reviewed; Journal article, 2022)There are large knowledge gaps concerning concentrations, sources, emissions, and spatial trends of mercury (Hg) in the atmosphere in developing regions of the Southern Hemisphere, particularly in urban areas. Filling these ... -
Mercury in fish from Norwegian lakes: The complex influence of aqueous organic carbon
(Journal article; Peer reviewed, 2018)Mercury (Hg) concentrations in water and biota are often positively correlated to organic matter (OM), typically measured as total or dissolved organic carbon (TOC/DOC). However, recent evidence suggests that higher OM ... -
Mercury in the Barents region – River fluxes, sources, and environmental concentrations
(Peer reviewed; Journal article, 2023)Arctic rivers are receiving increased attention for their contributing of mercury (Hg) to the Arctic Ocean. Despite this, the knowledge on both the terrestrial release sources and the levels of Hg in the rivers are limited. ... -
Mercury in the submerged macrophytes Potamogeton crispus and Chara virgate from the brackish, industrial affected Gunneklevfjorden, southern Norway
(Journal article; Peer reviewed, 2016)Kvikksølv i krustjønnaks Potamogeton crispus og kransalgen Chara virgate i Gunneklevfjorden, en industripåvirket brakkvannsfjord i Norge. Total kvikksølv (Tot-Hg) og metylkvikksølv (Met-Hg) ble analysert månedlig fra mai ... -
Mercury isotope analysis of sediments from Gunneklevfjorden – Method evaluation and a preliminary investigation of sources
(NIVA-rapport;7417, Research report, 2019)Gunneklevfjorden in south Norway is an aquatic system where the pollution history includes decades of local industry releases and emissions. An accurate estimate of the importance of ongoing and historic sources is critical ... -
Mercury Risk Evaluation, Risk Management and Risk Reduction Measures in the Arctic (ARCRISK) – Inception Report
(NIVA-rapport;7489, Research report, 2020)The project “Risk evaluation, risk reduction and risk management action plans for mercury in the Arctic – a circumpolar management approach” (ARCRISK) has been developed to address mercury pollution in the Arctic. The main ... -
Mercury–Organic Matter Interactions in Soils and Sediments: Angel or Devil?
(Journal article; Peer reviewed, 2019)Many studies have suggested that organic matter (OM) substantially reduces the bioavailability and risks of mercury (Hg) in soils and sediments; however, recent reports have supported that OM greatly accelerates Hg methylation ... -
Mesocosm study with thermally treated (TCC) and water-based drill cuttings (WBM)
(NIVA-rapport;7033, Research report, 2016)Mesocosm and bottle slurry experiments were conducted to assess and compare the effects of thermally treated cuttings (TCC) versus cuttings with water-based mud (WBM) on benthic communities. While WBM has been discharged ... -
Mesokosmos-forsøk med avgang fra Titania - effekt på bløtbunnsfauna
(NIVA-rapport;7223, Research report, 2017)Det er utført et mesokosmos-forsøk med gruveavgang fra Titania A/S, og den foreliggende rapporten har til hensikt å vurdere effekter på bløtbunnsfaunaen. Tilsetting av 2 cm avgangsmasser ga en betydelig reduksjon i tettheten ... -
Meta-analysis of multidecadal biodiversity trends in Europe
