RIVM has conducted research into the health risks of playing sports on synthetic turf fields with an infill of rubber granulate. The results of this research indicate that playing sports on these fields is safe. The risk to health from playing sports on these synthetic turf fields is virtually negligible. While rubber granulate contains harmful substances, these substances are only released from the rubber granulate in very small quantities after ingestion, contact with the skin or evaporation in hot weather. RIVM recommends adjusting the standard for rubber granulate to one that is closer to the standard applicable to consumer products.
