"Studies have shown that rubber crumb taken from synthetic turf fields contain hazardous materials such as volatile organic chemicals, including polycyclic aromatic hydrocarbons, and semi volatile organic chemicals (SVOCs). Over the past several years, worldwide public health concerns have been raised about the potential exposure of athletes to these compounds through inhalation, ingestion, or dermal contact with tire crumb rubber."

"With Dr. Vasilis Vasiliou and Dr. Anne Marie Jukic, we will be using mass spectrometry-based metabolomics and questionnaire data to assess human exposure and short-term health effects, leading the way for functional studies and interventions."

" 'Goalkeepers get it in their sides, hips, elbows, abrasions from sliding on the stuff. So if they have an open sore, not only the black dots but the dust particles that you can't even see when the tire crumb breaks down so small get in there. I'm sure you eat it and inhale it,' she said. 'Just in a 10-minute warmup, our keepers will hit the ground anywhere from 50 to 100 times.' "

"Since the investigation, Griffin said many more people have reached out to add names to her list."

" 'At this point, we see indicia, which we always see before there’s adequate proof of causation,' plaintiff's attorney Ted Tredennick with Daniels & Tredennick in Houston told Bloomberg BNA.

'We see clusters of people getting the same type of disease with the only common link being exposure to these fields,' he said. 'This comes before the science establishes causal links.' "

"As athletes with cancer continue to come forward, the government is investigating whether synthetic fields are truly safe."

"Existing studies by federal, state and local government agencies 'were not designed, nor were they sufficient in size or scope, to draw conclusions about the safety of all fields across the nation,' EPA spokeswoman Laura Allen told The Huffington Post. 'They cannot fully answer questions about what if any potential risks might be posed from exposure.' "

A natural experiment is being conducted in which thousands of children are being exposed on playing fields to rubber 1) known to contain carcinogens and 2) documented to produce cancer in workers in the tire manufacturing plants.

"And there are some serious health concerns. It’s not just about injury, either. What's in those little rubber pellets? I don't know. And I don’t want my kids to be the ones that suffer because they're the guinea pigs of some of these big turf companies wanting to make a ton of money. I think it’s not okay."

" 'We certainly didn't think that it was harmful because we never questioned what was in it, what the make of it was,' Leahy says. 'It was just a new surface that had a bit of cushioning.' "

"According to the report, the study revealed nearly 100 chemicals were found in the 14 samples they analyzed. The study also revealed 11 carcinogens in the turf samples, as well as 20 known skin irritants.

'I knew there were heavy metals in them but I never expected 96 chemicals,' said Nancy Alderman, President of Environment and Human Health, Inc."
