Unsafe Playfields
Artificial Surfaces Pose Risks

A majority of professional and college athletes strongly prefer natural turf because those playing on synthetic turf suffer about 50 percent more knee and ankle injuries.
Other playfields use “crumb rubber” infill made of ground-up used tires formerly considered hazardous waste. Thus, sports players may be exposed to dozens of chemical compounds, most of which have never been tested for health impact; some of those tested are believed to cause cancer, birth defects, developmental and reproductive disorders and infertility.
