The National Toxicology Program (“NTP”) recently announced that it intends to join the crowded playing field (pun intended) of state, federal, and international agencies that are evaluating the potential human health risks associated with synthetic turf fields. Synthetic turf fields have been the subject of ongoing assessment by U.S. EPA, the Agency for Toxic Substances and Disease Registry, the Consumer Product Safety Commission, California’s Office of Environmental Health Hazard Assessment, and the European Union’s chemicals agency. However, the NTP intends to focus specifically on the tire crumb rubber used in those turf fields and to conduct short-term in vivo and in vitro toxicology studies on the crumb rubber.
As more schools and other public facilities install synthetic turf fields, the potential health effects of the infill is an issue that is attracting increased attention. The NTP believes that its proposed study will help to fill what it views to be an important data gap. Although existing health study have not identified an elevated health risk from playing on artificial turf fields, these studies have generally focused on the potential health effects of exposure to lead other materials released from the artificial grass blades and/or exposure to possible emissions associated with the turf field in its entirety. NTP and U.S. EPA have noted that there are limited studies on the effects of exposure to the tire crumb materials specifically which will be the focus of the NTP study.
