Summary of Results

- Finalisation of the Citizen Science project "Sjekk kunsgressbanen"  which invovled more than 12500 pupils and almost 600 football games at almost 350 pitches

- Hitchhiking rubbercrumbs are removed in considerable amounts by players from the fields

- Established protocols for leachate analysis and extraction of leached compounds from seawater.

- Identified and established analytical methods for relative additive chemicals.

- Conducted leachate studies looking at the leaching of organic compounds (PAHs and additive chemicals) and metals from rubber granulates into seawater.

- Looked at variations in leachate concentration with size fraction (including cryomilled particles, 250-1500 µm and up to pristine soccer pitch particles) and rubber concentration (0.001-0.1 g/mL water).

- Examined the leachate profile variations between pristine rubber particles and rubber particles collected from soccer fields in Tromsø and Trondheim.

- Conducted a time-series leachate (0-30 days) to look at effect of leachate time on concentrations.

- Analysed leachate used in copepod exposure experiments. 

- Contaminats and additives were determined in both the rubber and seawater leachate with phenolic compounds dominating in the rubber leachate and metals in the ruber itsself

- Leaching is not affected by particle size

- Analysed the body burden of copepods exposed to rubber leachates.

 

 production of rubber leachates from 3 rubber types (Tromsø field, Trondheim field, Ragnsell medium pristine/new)

-  concentration gradients of leachates in filtered seawater: stocks (100%), 10%, 1% and 0.1%

-  preparation of leachates in all concentrations for chemical analyses and use in exposure experiments

-   exposure experiments with two species of planktonic marine copepods (Acartia longiremis, Calanus finmarchicus) in the low concentrations (10, 1 and 0.1%), to complement previous experiments (2017) with higher concentrations (5-100%)

-  determination of mortality rates in a long-term exposure over 2 weeks

-     preliminary data analysis of mortality data

-     exposure experiment with brown crabs (Cancer pagurus) in december 2018

- Organisation of a two day Science Session on MArine Plastic in the RActic at Arctic Frontiers 2019 and at NEST conference at Svlbard in February 2018

- One proposal to NFR MILJØFORSK call "Environmental behaviour of tire wear particles and their impacts on ecosystems

exposed to multi-stressors (ENTIRE)"

For the Management

Rubber crumb is a source of a number of pollutants which easily leach out into seawater. High mortality rates were observed for different plankton species, typical in Arctic waters (Calanus finmarchicus and Acartia longiremis). The prevention of rubber crumbs leaving artificial soccerfields uncontrolled, is a prerequisite for an efficient regulation of rubber crumb emissions and limitations of harmful effects to the marine environment.

Conclusions

 

Rubber crumb is a source of a number of pollutants which easily leach out into seawater. High mortality rates were observed for different plankton species, typical in Arctic waters (Calanus finmarchicus and Acartia longiremis). The prevention of rubber crumbs leaving artificial soccerfields uncontrolled, is a prerequisite for an efficient regulation of rubber crumb emissions and limitations of harmful effects to the marine environment. The impact on species higher in the food chain, as fex the brown crab, will be investigated in 2019 together with publishing and proposal writing.
