NORDUST : Nordic Road Dust Project
Road dust is an important contributor to airborne particle pollution, especially in the Nordic countries where high road surface wear, due to studded tyre use as well as winter maintenance and operations including sanding and salting are important contributors. Even though the road dust problems are similar, the countries have tackled different parts of the problem with different research approaches, resulting in a complex knowledgebase in need of compilation. A former project, NORTRIP, started this work and implemented the knowledge into an emission model with a specially elaborated road dust focus. The model work has been used to identify knowledge gaps, intended to be filled within the NorDust project.Laboratory tests and controlled and uncontrolled field measurements as well as parametrisation and modelling have been used as tools to find, describe and implement issues concerning road dust formation, suspension and dynamics and road operation effects on emissions in facilities and sites in finland and Sweden. The NORTRIP model has been implemented and evaluated in Iceland, not previously involved in the model development, to identify input data needs.The project has resulted in an array of findings, of which some have been possible to implement in new parametrisations in the NORTRIP model. In the complex research area of road dust dynamics, the project has also resulted in a lot of practical experiences concerning experimental and measurement designs and evaluation possibilities that future research will be able to benefit from.

Tiltaksutredning for lokal luftkvalitet i Tromsø
Tiltaksutredningen, med handlingsplan og tiltak, skal bidra til å redusere luftforurensningen til et nivå som tilfredsstiller kravene i forurensningsforskriften. Tiltaksutredningen omfatter en kartlegging av luftkvaliteten i Tromsø ved trafikkberegninger og utslipps- og spredningsberegninger for PM10, PM2,5 og NO2 for Dagens situasjon 2016 og Framtidig situasjon 2023 med og uten tiltak mot svevestøv. Basert på resultatene fra beregningene og i samarbeid med oppdragsgiver og arbeidsgruppen, er det foreslått en revidert handlings- og beredskapsplan som skal behandles politisk.

Assessment of additives used in plastic in seabirds
Liver samples from 10 herring gulls (Larus argentatus) were investigated for a broad range of chemicals used as additives in plastic products. The aim of this study was to clarify if the ingestion of plastic by seabirds would cause additives to leach out and get taken up by the organism, posing a potential harm. After chemical trace analyses of the liver samples, considerable concentrations of S/MCCPs and dechloranes were detected. Of the other additive classes analysed for, only sporadic detections were observed. In general, the results from chemical analysis of additives used in plastic do not indicate a relationship between gastric contents (plastic occurrence in the stomach) and additive concentration in the liver, in respect to the chemical compounds investigated here.

Europe's urban air quality — re-assessing implementation challenges in cities
This report analyses the implementation of EU air quality legislation at the urban level and identifies some of the reasons behind persistent air quality problems in Europe's cities. It is produced in cooperation with 10 cities involved in a 2013 Air Implementation Pilot project: Antwerp (Belgium), Berlin (Germany), Dublin (Ireland), Madrid (Spain), Malmö (Sweden), Milan (Italy), Paris (France), Plovdiv (Bulgaria), Prague (Czechia) and Vienna (Austria).

Screening new PFAS compounds 2018
This screening project has focused on the occurrence of conventional and emerging PFASs in terrestrial and marine environments, including the Arctic. Conventional PFASs were found to be wide-spread in the environment and for the first time in Norway reported in wolf, a top predator from the terrestrial environment. Otters living in close proximity to human settlements and preying on the marine food chain, are heavily contaminated with PFASs. Areas where ski-testing activities are common are a potential “hotspot” where PFASs can enter the food chain. The difference in PFAS-profile between the samples indicates that the diversity in samples are necessary to reveal the complete picture of PFASs in the environment.

Grenseområdene Norge-Russland. Luft- og nedbørkvalitet, årsrapport 2018.
Smelteverkene i NV-Russland slipper ut store mengder svoveldioksid (SO2) og tungmetaller. Utslippene påvirker luft- og nedbørkvalitet i grenseområdene. Miljøovervåkingen viser at grenseverdier for SO2 er overholdt i kalenderåret 2018, samt sesongmiddel vinter 2017/18. Målsettingsverdier for Ni og As er overholdt.
