Impact/Purpose:
The SOPs described in this document support the multi-agency federal research plan to characterize tire crumb rubber. The federal research action plan has three phases: (1) literature review and data gaps analysis; (2) tire crumb characterization research; and (3) human exposure characterization research. This document focuses on field and laboratory procedures used for the characterization of recycled tire crumb rubber materials and the pilot studies developed to characterize potential human exposures. The tire crumb rubber samples were collected from tire recycling plants and synthetic fields around the United States. The characterization of the tire crumb rubber samples included a wide range of chemical and microbial analyses and physical properties. The chemical laboratory analytes included metals, volatile organic compounds (VOCs), and semi-volatile organic compounds (SVOCs). The SOPs included in the appendices are formatted for field and laboratory use containing details used to collect and analyze the samples from tire recycling facilities and synthetic turf fields around the U.S.
Description:
This compilation of field collection and laboratory SOPs was assembled for the U.S. Environmental Protection Agency's (EPA) Tire Crumb Rubber Characterization Study (TRCS) Pilot Study. This study was developed to address data gaps associated with the safety and use of recycled tire crumb rubber in synthetic turf fields and playgrounds in the United States. The SOPs described in this document contribute to a multi-agency federal research action plan (https://www.epa.gov/chemical-research/federal-research-recycled-tire-crumb-used-playing-fields) to study key environmental human health questions associated with tire crumb rubber on synthetic turf fields and playgrounds. The federal agencies participating in the study include the EPA, the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (CDC/ATSDR), and the U.S. Consumer Product Safety Commission (CPSC).
