June 3, 2009 --The government is reconsidering whether playgrounds and sporting fields made from recycled tires could harm children's health. A group of scientists with the Environmental Protection Agency are raising new concerns following a limited study of play surfaces made from recycled rubber. They are urging the heads of their agency to approve a larger study.
The recycled rubber surfaces help reduce injures in play areas. They are also weatherproof and inexpensive. But research suggests that the bits of shredded tire can contain carcinogens and other harmful chemicals.
