In April 2024, the Environmental Protection Agency (EPA), in partnership with the CDC, ATSDR, and CPSC, published the largest
study on tire crumb rubber in synthetic turf fields conducted in the U.S. The research assessed chemical exposure levels in athletes using these fields. The findings indicated low chemical exposure, with no significant differences in polycyclic aromatic hydrocarbon (PAH) levels between users of synthetic turf and natural grass. Additionally, blood tests showed no significant increase in metal exposure for turf users, aligning with levels found in the general population. The study concluded that exposure to chemicals from recycled tire crumb rubber is minimal and comparable to natural grass, supporting results from prior research. Overall, the study reassures that synthetic turf fields do not pose significant health risks related to chemical exposure.
