EXCERPTS FROM THE ARTICLE:
A new study led by Yale’s Gaboury Benoit, Professor of Environmental Chemistry and Engineering, could add to those concerns. It looks at the chemical makeup of rubber tire infill - made from recycled shreds of old tire - and rubber tire mulch, also made from recycled rubber tires.
One of the study’s findings is that of the 96 chemicals detected, almost half of them had no toxicity screenings to determine their health effects. The other chemicals underwent incomplete toxicity assessments. And of those, 20 percent are considered probable carcinogens. Additionally, 40 percent are found to be irritants causing problems for either breathing, the skin or the eyes.
