    Thursday, July 2, 2015, 8:00 PM - Heading outdoors to take part in sports and play is a part of daily active lifestyle, typically encouraged and applauded for an array of health benefits.

    But a new study says that all depends on where you play.

    Toxic particles found in playgrounds and sports field contain cancer-causing chemicals, according to new research.

    The tiny particles, known as "crumb rubber" or "in-fill," are made from recycled tires, and used to surface playground flooring and synthetic turf fields.

    The recycled rubber is often seen laid down in tile formations beneath playground equipment. Tire crumb materials are spread five to eight centimetres thick over field surfaces and packed between ribbons of green plastic used to simulate green grass.

    According to the Yale University-led study, half of the compounds found in the substance are considered toxic. Most of the particles are carcinogens or irritants, which can cause respiratory issues including asthma.

    "Tires are a hazardous waste, and I find it surprising that if we have them converted into a consumer product, they're no longer considered a hazardous waste," said Dr. Gaboury Benoit, a Yale University professor and leader of the study.

    The study was commissioned by a group of doctors and public health professional after they received numerous inquiries and concerns in regards to children's exposure to the crumb rubber in playgrounds and sports fields across the United States.

    Playground turf made from recycled rubber is considered to be a more durable, softer playing surface, minimizing the risk of injuries from falls. Turf is also more cost-effective than natural grass, making it an appealing alternative for school board budgets.

    Manufacturers have long defended that fake grass fields made with ground rubber are safe. But as more research is done, an alarming number of health issues associated with the artificial turf may build a case against it.

    In a separate study by the University of Washington, of 124 soccer players identified as having some form of cancer, 85 players were goalies. All 124 people previously played on fields made of synthetic turf.

    Studies arguing for and against the use of rubber in synthetic play areas and fields have been ongoing, with little evidence to substantiate the claim that all artificial fields increase the risk of cancer.

    In 2014, players from the United States Women's National Soccer team sued soccer organization FIFA, when it was announced the all games at the 2015 Women's World Cup in Canada would be played on artificial turf instead of grass.

    “I don’t think there’s anything that compares to a well-taken care of grass pitch,” said Alex Singer, a defender for the Washington Spirit, a women’s pro team in the U.S. “Grass feels good. It smells good. It’s good for my body as well.”

    The suit against FIFA was later dropped, and all games played out on turf.
