Artificial turf as an alternative to natural grass has become popular in recent years, especially in athletic field applications. Among the benefits often cited are durability and low maintenance costs. Today, new manufacturing technologies are producing surfaces designed to be even softer and more yielding to help prevent injuries. However, many are questioning the safety of long-term exposure to these new surfaces.
Crumb rubber turf is made from recycled tires which are known to contain carcinogenic materials. This has led some to suggest that playing on artificial surfaces made from this material is increasing the risk of cancer for many children.
