The health of thousands of children may be at risk from long-term exposure to toxic chemicals from artificial turf that has become a popular replacement for grass on sporting ovals and school playgrounds around the country. Australian scientists have raised the alarm over the potential dangers of the fake grass, and called for a moratorium on its use until its safety can be established….But Mariann Lloyd-Smith, of the National Toxics Network, a non-government group of scientists and community members, said: ”Children are at greatest risk because of their activities – particularly hand-to-mouth ingestion. And we know that children are so much more susceptible to hazardous materials.”
