Request to National Toxicology Program to Conduct Toxicological Studies on Health Impacts of Chemicals Released from Synthetic Turf

The Office of Environmental Health Hazard Assessment (OEHHA) has requested that the National Toxicology Program (NTP) to conduct toxicological studies to enhance our understanding of the health impacts of chemicals released from synthetic turf, with an emphasis on the crumb rubber in the fields.  There is an urgent need for such toxicological information given that exposures are ongoing and involve children.  OEHHA is conducting a Synthetic Turf Study that will provide exposure information and ultimately a health impacts assessment.  There are many chemicals released from crumb rubber.  Some chemicals have toxicity information, but little toxicity data on many released chemicals, and there is very limited information on crumb rubber as a whole.  OEHHA requested NTP to conduct short-term in vivo and in vitro toxicology studies on crumb rubber.  Information gained from such studies would help OEHHA evaluate health impacts associated with the use of crumb rubber in synthetic turf fields and playground mats.
