Summary of Results

We carried out the deployment of virgin and post-use plastic particles at Ny Ålesund, Svalbard during two campaigns; summer and winter 2017/8 for a period of 6 months each. Five timepoints per campaign were sampled. All samples were transfered to the NILU lab at the FRAM centre and prepared according to established methods to analyse for PBDEs, HCB and PCBs. All samples were measured using the Orbitrap GC-HRMS for ultratrace sensitivity. The estalishment of adsorption kinetics is under way. Additionally we investigated the change of the polymeric composition (weathering) over time using FTIR measurements. Also measurements with electronmicroscope at the University of Tromsø was carried out, to investigate the change of surface characteristics over time under Arctic conditions. 

 

To assess the real environmental contribution of marine plastic litter to the POP load in the Arctic a selection of beach litter collected at Longyearbyen was also investigated. The developed kinetics will potentially enable us to estimate how much time the respective plastic waste has spend in the marine environment.

Tittel: Microplastic as a vector of Persistent organic pollutants in the Arctic Environment

For the Management

Pollutants and microplastic are closely interlinked, and we are able to measure a broad range of pollutants in microplastic samples. 

The ubiquiteous presence of microplastic in the marin environment will also cause an ubiquiteous distribution of pollutants. Microplastic act as a vector of a broad range of pollutants, some of which are normally not prone to Long-Range-transport to the Arctic and fragile parts of the marin eecosystem.

Conclusions

- Arctic conditions cause a different absorption behaviour than observed in temperate regions 

- Adsorbed POP load is considerably lower in Arctic regions compared to temperate regions 

- The produced data will give us a much improved understanding about the amounts of POPs carried to the Arctic via marin plast

- We will improve our understanding about the adsorbtion kinetics of POPs under Arctic conditions c
