Microbial dynamics in RAS water: Effects of adding acetate as a biodegradable carbon-source
(Journal article; Peer reviewed, 2019)This study evaluated the effect of an abrupt increase in easily biodegradable carbon (acetate) on bacterial activity and abundance in the water of recirculating aquaculture systems (RAS). The study included a batch experiment ... -
The MicroClimate Screen – A microscale climate exposure system for assessing the effect of CO2, temperature and UV on marine microalgae
(Peer reviewed; Journal article, 2022)Global warming and anthropogenic activities are changing the ocean, inducing profound impacts on marine life and ecosystems from changing physical and chemical factors in and above the water column. Rising surface temperatures, ... -
Microcystin profiles in European noble crayfish Astacus astacus and water in Lake Steinsfjorden, Norway
(Peer reviewed; Journal article, 2024)Lake Steinsfjorden, an important noble crayfish (Astacus astacus) habitat, is often affected by blooms of Planktothrix spp. that produce microcystins (MCs). A poor correlation between MCs by ELISA in the water and in ... -
Microcystins in European Noble Crayfish Astacus astacus in Lake Steinsfjorden, a Planktothrix-Dominated Lake
(Peer reviewed; Journal article, 2020)Lake Steinsfjorden, an important Norwegian location for noble crayfish (Astacus astacus), is often affected by cyanobacterial blooms caused by microcystin (MC)-producing Planktothrix spp. The impact of MCs on noble crayfish ... -
Microcystis, Raphidiopsis raciborskii and Dolichospermum smithii, toxin producing and non-toxigenic cyanobacteria in Yezin Dam, Myanmar
(Peer reviewed; Journal article, 2021)Yezin Dam is a man-made reservoir located close to Yezin village in Myanmar. Its water is used for irrigation, domestic purposes and as drinking water for many urban communities in the watershed area. In recent years, ... -
Microfiber Hotspots’ Association with Ships in a Remote Port before and during Covid-19
(Peer reviewed; Journal article, 2023)During monthly water quality monitoring of Norwegian coastal waters, the sea surface waters off Brønnøysund, a remote port in Norway, exhibited an unexpectedly high abundance of microfibers. We further conducted monitoring ... -
Microplastic retention by marine vegetated canopies: Simulations with seagrass meadows in a hydraulic flume
(Peer reviewed; Journal article, 2021)Marine canopies formed by seagrass and other coastal vegetated ecosystems could act as sinks of microplastics for being efficient particle traps. Here we investigated for the first time the occurrence of microplastic ... -
Microplastic variability in subsurface water from the Arctic to Antarctica
(Peer reviewed; Journal article, 2022)Comparative investigations of microplastic (MP) occurrence in the global ocean are often hampered by the application of different methods. In this study, the same sampling and analytical approach was applied during five ... -
Microplastics could be marginally more hazardous than natural suspended solids - A meta-analysis
(Peer reviewed; Journal article, 2023)Microplastics (MP) are perceived as a threat to aquatic ecosystems but bear many similarities to suspended sediments which are often considered less harmful. It is, therefore pertinent to determine if and to what extent ... -
Microplastics distribution in the Eurasian Arctic is affected by Atlantic waters and Siberian rivers
(Peer reviewed; Journal article, 2021)Plastic pollution is globally recognised as a threat to marine ecosystems, habitats, and wildlife, and it has now reached remote locations such as the Arctic Ocean. Nevertheless, the distribution of microplastics in the ... -
Microplastics in arctic invertebrates- Status on occurrence and recommendations for future monitoring
(Peer reviewed; Journal article, 2022)Few studies have been published on occurrence and distribution on microplastics (MPs) in invertebrates from the Arctic. We still need to develop harmonised methods to enable good comparison between studies taking into ... -
Microplastics in beach sediments and cockles (Anadara antiquata) along the Tanzanian coastline
(Peer reviewed; Journal article, 2020)Little is known about the prevalence of microplastics (MPs) in East Africa. In the present study, sediments were sampled at 18 sites along the Tanzanian coast that exhibit different levels of anthropogenic activity and ... -
Microplastics in grey seal (Halichoerus grypus) intestines: Are they associated with parasite aggregations?
(Journal article; Peer reviewed, 2019)Between 2012 and 2015, 13 grey seals were recovered from trammel nets targeting monkfish and rays off the south coast of Ireland. Incidence and distribution of microplastics were investigated along the intestines of bycaught ... -
Microplastics in marine environments: Occurrence, distribution and effects
(NIVA-rapport;6754, Research report, 2014)This report reviews the current understanding of the occurrence, distribution and effects of microplastics on the marine environment. Most members of the public are aware of, or have seen the impacts of, litter pollution ... -
Microplastics in Norwegian coastal areas, rivers, lakes and air (MIKRONOR1)
(NIVA-rapport;7811-2023, Research report, 2022)The Norwegian Environment Agency (Miljødirektoratet, NEA) tasked the Norwegian Institute for Water Research (NIVA) to initiate Norway’s National microplastic monitoring program. The program “Microplastics in Norwegian ... -
Microplastics in road dust – characteristics, pathways and measures
(NIVA-rapport;7526, Research report, 2020)The expected main contributors to road dust-associated microplastic particles (RAMP) are rubber compounds in tyre treads, polymers used to strengthen the bitumen used in road pavement and thermoplastic elastomers used in ... -

Microplastics in sea-surface waters surrounding Sweden sampled by manta trawl and in-situ pump
(Peer reviewed; Journal article, 2020)Microplastics were sampled in open surface waters by using a manta trawl and an in-situ filtering pump. A total of 24 trawl samples and 11 pump samples were taken at 12 locations around Sweden. Overall, the concentration ... -
Microplastics Removal from a Plastic Recycling Industrial Wastewater Using Sand Filtration
