Artificial Turf Wars.

The article reports on the testing of installing artificial turf fields with crumb rubber infill. According to Nancy Alderman, the president of the environmental group Environment and Human Health Incorporated (EHHI) which suggested the infill, the infill has some green credibility because it's made of recycled rubber tires, but it poses a human health risk. Mary Jane Martina, analytical chemist at the Connecticut Agricultural Experiment Station (CAES), the group commissioned to test for any leaching of harmful chemicals as a result of heat or water contact, and her team at CAES found several compounds being emitted by the tire crumbs when subjected to heat, three of which can cause skin and eye irritation in large amounts, and one known carcinogen.
