Limited EPA Study Finds Low Level of Concern in Samples of Recycled Tyres from Ballfield and Playground Surfaces.Release date: 12/10/2009
Recycled tyre material, or “tyre crumb,” is used in many applications, including as a component in synthetic turf fields and playground installations. In response to concerns raised by the public, EPA conducted a limited “scoping study” of tire crumb, which consisted of collecting air and wipe samples at three locations near EPA laboratories at Raleigh, N.C., Athens, Ga., and Cincinnati, Ohio. Sampling also was conducted in the Washington, D.C. area.
The limited study, conducted in August through October 2008, found that the concentrations of materials that made up tyre crumb were below levels considered harmful.
