RIVMNational Institute for Public Health and the Environment used a variety of methods to obtain more knowledge about rubber granulate on synthetic turf fields and the possible health effects. RIVM carried out a systematic review to assess all the relevant scientific publications. These findings were combined with field research to clarify which substances are contained in rubber granulate. Another aspect of the research was a laboratory analysis of a selection of the samples taken from synthetic sports fields to determine the extent to which substances can be released in certain circumstances, for example through contact with the skin or ingestion of the granulate. RIVM has conducted the research in collaboration with many other parties.
In March 2017 RIVM published a compilation of the initial 2016 report and all the scientific background documents:' Evaluation of health risks of playing sports on synthetic turf pitches with rubber granulate : Scientific background document.'
