Spredningsberegninger av luftforurensning fra Sunndal Metallverk

Weydahl, Torleif

Rapporten presenterer spredningsberegninger for utslipp til luft fra Hydro Sunndal sitt smelteverk i Sunndalsøra for nåsituasjonen med utslippsmengder som i gjeldende utslippstillatelse, og en situasjon med ny utvidet anodefabrikk. Det er beregnet bakkekonsentrasjoner av SO2, støv, fluorider, PAH og metallkomponenter. Det er også gjort beregninger for utslipp i perioden 23. mai til 15. august 2019 hvor NILU utførte målinger av disse komponentene. Basert på beregningene er det vurdert «lav til moderat» risiko for overskridelse av forskriftens målsettingsverdi for nikkel i området nær anlegget. Ny anodefabrikk har ingen vesentlig betydning for konsentrasjonsnivåer utenfor metallverket som er relevant i forhold til gjeldende grenseverdier eller luftkvalitetskriterier.

Environmental Contaminants in an Urban Fjord, 2023

Ruus, Anders; Grung, Merete; Bæk, Kine; Rundberget, Thomas; Vogelsang, Christian; Beylich, Bjørnar; Lund, Espen; Allan, Ian; Ribeiro, Anne Luise; Hanssen, Linda; Enge, Ellen Katrin

This report presents data from the third year of a new 5-year period of the Urban Fjord programme. The programme started in 2013 and has since been altered/advanced. In 2023 the programme covers sampling and analyses of sediment, blue mussels and cod from the Inner Oslofjord, as well as water and trout from Alna River. In addition, samples of stormwater, and waste water from Bekkelaget wastewater treatment plant, are analysed. A total of ∼230 single compounds/isomers were analysed, and frequent detection was found of specific PFAS compounds in aqueous phases, other specific PFAS compounds in fish liver, certain QACs in particulate phases, certain benzothiazoles in aqueous phases, chlorinated paraffins (MCCP in particular) in sediment and biota, certain siloxanes in biota and particulate phases, metals in all matrices, and PCBs in sediment and biota.

Screening of compounds in tire wear road run off

Hanssen, Linda; Schmidt, Natascha; Nikiforov, Vladimir

Tire related additive chemicals can leach out and enter the environment. Road run-off and recipient waters are particularly prone to contamination by these chemicals, though data from large screening studies is lacking. Here, we present data from water (road run-off & recipients, atmospheric deposition (rain), snow), sediment (marine, snow dumping sites) and biota (blue mussels) samples collected in the Nordic countries. The aim of this study was to provide a first assessment of the presence of tire related chemicals in road run-off and associated samples in the Nordic countries. Tire related additive chemicals were detected in 85 out of 87 samples, with varying concentrations depending on the sample type and location.

The FAIRness of ACTRIS Data Centre

Myhre, Cathrine Lund; Fiebig, Markus; Rud, Richard Olav; Mona, Lucia; Dema, Claudio; Pascal, Nicolas; Henry, Patrice; Picquet-Varrault, Bénédicte; Brissebrat, Guillaume; Boonne, Cathy; O'Connor, Ewan; Tukiainen, Simo

The purpose of this report is to document the status and implementation of FAIRness within ACTRIS Data centre as of March 2023, developed over the period January 2019 – March 2023.

The report is an extended version of ENVRI-FAIR deliverable D8.4 due March 2023 and available through Zenodo: ENVRI-FAIR D8.4: The FAIRness of ACTRIS | Zenodo, only including the work until autumn 2022. This present report adds more information to the implementation of the FAIR principles by ACTRIS Data Centre over the period January 2019 – March 2023. In addition to D8.4, the present report provides a comprehensive external FAIRness assessment covering the entire period 2019 - 2023, along with an evaluation of the implementation in the years 2022 and the first half of 2023. It's important to note that the project deliverable only encompasses the period from 2019 to 2021.
