The Ecology Center, a Michigan-based non-profit environmental organization, was contacted by the Safe Healthy Playing Fields regarding concerns about metals and other chemicals of concern that may be in rubber shred-based poured-in-place (PIP) playgrounds and athletic fields. The Ecology Center has been conducting ongoing analysis of samples provided by Safe Healthy Playing Fields, concerned community members, investigative reporters and other interested parties.
The results of these sample sets are comparable to dozens of other PIP playgrounds we have tested over the last two years. Rubber shred materials sampled were very heterogeneous in terms of lead levels. Dissection of individual shreds with lead greater then 1,000 ppm illustrates that lead is uniformly distributed through a single rubber shred. This study did not assess the fate, release rate or potential exposures from lead-containing shred.
A summary of the test results from the 96 shreds is show below:
WUSA TV in Washington DC reported on the study and the subsequent closure of the two playgrounds identified with high lead levels.
