Pitches with artificial turf can be used at all hours and all year. They are therefore very space efficient and become increasingly common. But questions have been raised about the environmental issues that may arise from them. It has previously been known that artificial turf is a source of unwanted chemicals and recently they have been identified as the second biggest source of leakage of micro-plastic particles in Sweden. Such particles could affect biota negatively if they are released into nature. Since the state of knowledge was uncertain about migration of micro-plastic particles from artificial turf via their drainage, tests were made in draining wells at a selected number of artificial turf fields in municipality of Södertälje. To be able to answer if artificial turf is considered to have an environmentally damaging effect, a review of requirements and laws related to them were also made. Estimated quantities of granulate found during tests showed small amounts and conclusions were made that there must be another migration than through the drainage that contributes to the large leakage of micro particles of plastic from artificial turf. However, the study shows that the granulate can migrate through the drainage system and thus make it through to aquatic environments. Review of requirements and laws showed that environmental aspects linked to artificial turf several times are undefined and unclear and sometimes completely missing. Questions are raised if artificial turf should be seen as an activity where notification, authorization and supervision based on the environmental perspective are used, and which parties who have the responsibility in the matter. With additional information about that part of the filling material produced in Sweden and thus posted on artificial turf fields around the country are classified as waste, again raises questions about responsibility but also about governing agencies and their position on the subject. Concluding proposals are given for measures that could help to municipalities' efforts to minimize the risk of migration of rubber granules to nature.
