Kids at risk by ground-up tires in playgrounds?
Government studies material in play areas after scientists raise concerns

SAN FRANCISCO - The federal government is reconsidering whether sports fields and playgrounds made from ground-up tires could harm children's health after some Environmental Protection Agency scientists raised concerns, documents show.

The EPA is concluding a limited study of air and surface samples at four fake-surface fields and playgrounds that use recycled tires — the same material used under the Obama family's new play set at the White House.

Although the EPA for years has endorsed recycled-rubber surfaces as a means of decreasing playground injuries, its own scientists now have pointed to research suggesting potential hazards from repeated exposure to bits of shredded tire that can contain carcinogens and other chemicals, according to internal EPA documents.

The scientists cited gaps in scientific evidence, despite other reviews showing little or no health concern, and urged their superiors to conduct a broad health study to inform parents on kids' safety.

Results from the agency's limited study, which began last year, are expected within weeks.

"From everything I've been able to see, I'm not sure there's an imminent hazard but it's something we're investigating," said Michael Firestone, EPA's head of children's health protection. "It's critical to take a look at all the data together."

The government hasn't decided whether broader testing is necessary.

Easy on the bones, great for recycling
Synthetic sports surfaces are easy on the bones and great for recycling, increasingly popular for their resiliency and for their weatherproof, low-maintenance qualities. But communities from New Jersey to Oregon have raised concerns about children touching, swallowing or inhaling lead, metals and chemicals like benzene, zinc and breathable particles from synthetic fields and play yards.

Last week, New York state officials said they found no significant health or environmental concerns in a study of leaching and breathable air above sports fields with so-called tire crumb, tiny rubber infill pellets that help anchor the synthetic grass blades. Other local studies have reached similar conclusions, examining artificial grass or tire crumb. Several have recommended additional research.

"If they really find it's something toxic, I would be concerned," said Alejandro Arroyo, a teacher watching his high school students from June Jordan School for Equity play soccer at San Francisco's Crocker Amazon Park. The scent of tire rubber wafted over the busy, five-field complex as a dozen third-graders flopped onto artificial turf infused with gravel-sized, black rubber.

"We practice here, we eat lunch here," Arroyo said. "Everybody does that. It's a family park."

Scrap tire mulch cushions the ground under the Obamas' new play set at the White House. It was recommended by the National Recreation and Park Association, which relies on the industry's safety assurances and recommendations by the Consumer Product Safety Commission for cushioning the impact of falls, said Richard Dolesh, public policy officer for the park association.

But New York City officials say their new sports fields no longer will use tire crumbs. Connecticut asked the EPA to study the matter shortly after the EPA's Denver regional office recommended the same.

(Seems like a good use of old tires but further studies are needed.)
