Do DOM quality and origin affect the uptake and accumulation of lipid-soluble contaminants in coastal filter feeders? An experimental simulation of teflubenzuron exposure to blue mussels
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-25)The increased export of terrestrial dissolved organic matter (terrDOM) to coastal marine ecosystems may affect local filter feeders and the local food web via the altered uptake of organic material and associated contaminants. To compare terrDOM to marine DOM (marDOM) as contaminant vectors to coastal biota, we exposed blue mussels (Mytilus sp.) to the different DOM types in combination with ... -
Food and chemical substances relevant for monitoring - Scientific Opinion of the Scientific Steering Committee of the Norwegian Scientific Committee for Food and Environment
(Research report; Forskningsrapport, 2022-06-09) -
Food and chemical substances relevant for monitoring. Report from the Scientific Steering Committee of the Norwegian Scientific Committee for Food and Environment.
(Research report; Forskningsrapport, 2022)At request from the Norwegian Food Safety Authority (NFSA), VKM has identified food groups and food items consumed by the Norwegian population that are relevant for monitoring regarding content of one or more undesirable chemical substances (Figure 1). Undesirable chemical substances were defined as chemical substances in food that may constitute a potential health risk.<p> <p>VKM has created ... -
Genome editing in food and feed production – implications for risk assessment
(Research report; Forskningsrapport, 2021-10-29)The Norwegian Scientific Committee for Food and Environment (VKM) initiated this work to examine the extent to which organisms developed by genome-editing technologies pose new challenges in terms of risk assessment. This report considers whether the risk assessment guidance on genetically modified organisms, developed by the European Food Safety Authority ... -
Genome editing in food and feed production – implications for risk assessment. Opinion of the Steering Committee of the Norwegian Scientific Committee for Food and Environment
(Forskningsrapport; Research report, 2021-10-29)I denne rapporten vurderer Vitenskapskomiteen for mat og miljø (VKM) utfordringer knyttet til helse- og miljørisikovurdering av genomredigerte organismer til mat- og fôrproduksjon. VKM har gått gjennom veiledningen for risikovurdering av genmodifiserte organismer (GMO) som Den europeiske myndighet for næringsmiddeltrygghet (EFSA) har utviklet, og vurdert om veiledningen også kan brukes til å ... -
Implications of Coastal Darkening for Contaminant Transport, Bioavailability, and Trophic Transfer in Northern Coastal Waters
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-13)The increased transport of terrestrially derived organic material (tOM) from catchments to rivers and lakes is leading to browning of northern freshwaters.(1) Although the same environmental drivers can be expected to lead to widespread increases in tOM and subsequent darkening in adjacent coastal systems,(2) this has received considerably less attention, and long-term monitoring data for detecting ... -
Land-cover, climate and fjord morphology drive differences in organic matter and nutrient dynamics in two contrasting northern river-fjord systems
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-31)Climate and land-use changes are leading to impacts on individual ecosystems as well as shifts in transfer dynamics between interconnected systems. At the land-ocean interface, changes in riverine inputs of organic matter (OM) and nutrients have the potential to lead to shifts in coastal carbon and nutrient cycling with consequences for ecosystem structure and function. In this study, we assess OM ... -
Matproduksjon, mattrygghet og miljø - innspill om kunnskapsbehov til gjennomføringen av det grønne skiftet - Uttalelse fra hovedkomiteen i Vitenskapskomiteen for mat og miljø (VKM)

Microplastics; occurrence, levels and implications for environment and human health related to food. Opinion of the Steering Committee of the Norwegian Scientific Committee for Food and Environment
(Research report; Forskningsrapport, 2019-10-12)The steering committee of VKM has self-initiated a mandate for an opinion on microplastics based on recently published international and/or national reports complemented with literature from December 2016 to February 2019. The mandate requested a summary of the state of knowledge on the presence of microplastics in the environment and the implications for the ecosystem, terrestrial and aquatic ... -
Protocol and description of literature searches for the risk-benefit assessment of fish in the Norwegian diet. The Steering Committee of the Norwegian Scientific Committee for Food and Environment
(Research report; Forskningsrapport, 2020)Fish contains nutrients that are positive for our health. At the same time, it contains varying levels of undesirable substances that can have a negative effect on health. Undesirable substances can be found in different levels in most types of food. In a risk-benefit assessment, both the nutrients and the undesirable substances are assessed and it is evaluated whether it in total gives a more ... -
Ranking of substances for monitoring in foods, drinks and dietary supplements - based on risk and knowledge gaps
(Research report; Forskningsrapport, 2019)The Norwegian Food Safety Authority (NFSA) requested the Norwegian Scientific Committee for Food and Environment (VKM) to provide an overview of substances in foods, drinks and dietary supplements that may constitute a potential health risk for humans, based on the VKM members’ expert judgements. VKM was further requested to perform a ranking of these substances. Additionally, VKM should ...
