The increasing importance attached to scholastic sports programs has fueled demand for uniform, all-season sports fields, and many communities are considering the installation of artificial turf as a solution. Today's generation of artificial turf fields are typically filled with up to ten tons of ground-up truck and automobile tires. This recycled rubber contains high levels of toxic substances which prohibit its disposal in landfills and oceans.

Recent studies conducted in Connecticut and New York have confirmed the presence of hazardous materials on existing fields. Chemical toxins identified included the metals arsenic, cadmium, chromium, cobalt, lead and zinc, the chemicals acetone, ethylbenzene, tetrachloroethene, toluene and xylene, and phthalates. High temperatures recorded at field level can significantly increase the volatility of some of these chemicals. See the index to our Digest of Independent Science on Public Health Concerns Regarding Synthetic Turf.

While advocates claim the fields are safe, the potential health effects of exposure to these chemicals - endocrine disruption, neurological impairment and cancer - can take years to manifest themselves. Without long-term field testing, no one is in a position to say the exposure is harmless, particularly for children.

And there are other problems: cleaning synthetic turf can require harsh chemicals, and body fluid spills are particularly difficult to handle. Additional concerns about the eventual disposal of artificial fields, potential legal liability and the loss of environmentally beneficial natural turf, which sequesters carbon dioxide and reduces global warming, has convinced many decision makers to reconsider plans for synthetic turf fields.
