Abstract/OtherAbstract:
Synthetic athletic tracks and turf areas for outdoor sporting grounds may release contaminants due to the chemical composition of some components. A primary example is that of zinc from re-used scrap tires (main constituent, styrene butadiene rubber, SBR) - that might be harmful to the environment. Thus methods for the risk assessment of those materials need to be developed. Laboratory leaching methods like batch and column tests are widely used to examine the soil-groundwater pathway. We tested several components for artificial sporting grounds with batch tests at a liquid-to-solid (LS) ratio of 2 L/kg and column tests with an LS up to 26.5 L/kg. We found a higher zinc release in the batch test eluates for all granules, ranging from 15 % higher to 687 % higher versus data from column tests for SBR granules. The accompanying parameters, especially the very high turbidity of a special ethylene propylene diene monomer rubber (EPDM), or thermoplastic elastomer (TPE) eluates, reflect the stronger mechanical stress of batch testing. This indicates that the batch test procedure might not be suitable for the risk assessment of synthetic sporting ground components. Column tests on the other hand represent field conditions more closely and allow for determination of the time dependent contaminants release.
