NTP Synthetic Turf/Recycled Tire Crumb Rubber Research: NTP Studies
NTP is conducting research to enhance the understanding of potential health impacts of chemicals released from synthetic turf with an emphasis on the crumb rubber. NTP’s research program is in response to a request in November 2015 from the California Office of Environmental Health Hazard Assessment as part of its Environmental Health Study of Synthetic Turf. In conjunction with the extensive characterization of human exposure potential conducted as part of the California Office of Environmental Health Hazard Assessment study and the Federal Research Action Plan, the NTP’s research program will substantially contribute to what is known about potential human health effects of playing on synthetic turf fields made from recycled tires.
|Chemical characterization||Identify the chemical composition of the crumb rubber.|
|In vitro assays||Cell-based tests to assess the bioaccessibility and biological effect of crumb rubber constituents.|
|Female mouse 14-day||Short-term in vivo studies via oral gavage, dosed feed, or mixed bedding to assess the potential for systemic exposure to crumb rubber constituents with assessment of limited toxicological endpoints.|
