WASHINGTON (Sept. 1, 2016) —Three federal agencies have published a research protocol for their study evaluating the safety of recycled crumb rubber used in athletic fields and playgrounds.
The 251-page protocol — released jointly Aug. 5 by the U.S. Environmental Protection Agency (EPA), the Center for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (CDC/ATSDR) and the Consumer Product Safety Commission (CPSC) — follows the joint action plan the agencies released in February 2016 to evaluate the health and environmental effects of chemicals released by crumb rubber in the ground.
Several studies already exist that examine the possible effects of exposure to crumb rubber infill, the protocol states in its executive summary.
“While, in general, these studies have not provided evidence for these health concerns, the existing studies do not comprehensively evaluate all aspects of exposure associated with these use scenarios,” the summary said.
The research protocol is designed to implement three crucial research elements described in the action plan. These are:
- Conducting a literature review and data gaps analysis;
- Performing tire crumb-rubber characterization research; and
- Performing human-exposure characterization research.
