Migration analysis of chemical additives from indoor consumer plastic products
NILU has, on behalf of the Norwegian Environment Agency, performed chemical analyses of a selection of chemical additives in indoor consumer plastic products. The goal was to identify content and migration of the chemical additives in and from the products to particles and surfaces of the products at room temperature. The plastic products included; furniture wrap, wall papers, table cloths, shower curtains, floor tiles, mattresses, pillows, carpet underlays and a bathtub mat. Targeted chemicals were organophosphorous flame retardants (OPFRs), brominated flame retardants (BFRs) including tetrabromobisphenol A (TBBPA), chlorinated paraffins (CPs) and dechloranes. MCCPs and SCCPs were found in ‰ to % levels in PVC containing products. Four of the OPFRs were found in up to ‰ levels in adhesive foils to be put on furniture or floor/walls and mattresses. None of the targeted brominated compounds nor melamine were detected in the product samples.

The atmosphere and cryosphere have recently garnered considerable attention due to their role in transporting microplastics to and within the Arctic, and between freshwater, marine, and terrestrial environments. While investigating either in isolation provides valuable insight on the fate of microplastics in the Arctic, monitoring both provides a more holistic view. Nonetheless, despite the recent scientific interest, fundamental knowledge on microplastic abundance and consistent monitoring efforts are lacking for these compartments. Here, we build upon the work of the Arctic Monitoring and Assessment Programme's Monitoring Guidelines for Litter and Microplastic to provide a roadmap for multicompartment monitoring of the atmosphere and cryosphere to support our understanding of the sources, pathways, and sinks of plastic pollution across the Arctic. Overall, we recommend the use of existing standard techniques for ice and atmospheric sampling and to build upon existing monitoring efforts in the Arctic to obtain a more comprehensive pan-Arctic view of microplastic pollution in these two compartments.

Microplastics in Norwegian coastal areas, rivers, lakes and air (MIKRONOR1)
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 coastal areas, rivers, lakes and air (MIKRONOR)”, was designed to target the multitude of environments in the Norwegian coastal, freshwater and terrestrial ecosystems. The primary aim is to provide information on levels and types of microplastics in aquatic environments as well as in air and build on the baseline data already generated for a number of these environments on previous assignments by NEA.
This report contains the first results of coastal sites, open marine waters, lakes, rivers and air including high-volume water samples (freshwater and marine, n=48), Ferrybox samples (marine, n=20), blue mussels (marine, n=71), vertical plankton net samples (marine, n=29) and 24 air samples (precipitation n= 12 and active air sampling n = 12).
