Thousands of playgrounds and sports fields around the country have been covered with crumb rubber from recycled tires, and some experts and lawmakers are concerned about possible health effects on children. Dr. Homero Harari, with the Institute for Exposomic Research at Mount Sinai in New York, spoke to The Guardian about the chemicals found in used tires. “The main concern is that there was a lack of safety testing prior to the introduction of the material in playing surfaces,” Harari said. “As scientists, we normally apply the precautionary principle – when we know that there’s concern about a substance or chemical, we normally try to avoid it.” Crumb rubber often breaks apart, spreading into the air children breathe and getting swallowed when kids put their hands in their mouths.

Lauren Petrick, PhD, Assistant Professor in the Department of Environmental Medicine at Public Health and member of the TCEEE was one of 11 investigators who presented their research during the “Early Stage Investigator Poster Presentations” session at the 30th annual meeting of the National Institute of Environmental Health Sciences Environmental Health Science Research Centers (EHSRC). The meeting was held at the University of Iowa from June 19-21st, 2019. Dr. Petrick’s presentation “Prospective exposomic analysis of archived newborn blood spots in childhood leukemia” highlighted her study examining approximately 300 childhood acute lymphoblastic leukemia cases and controls that used remainder blood spots from neonatal screening tests. They had been archived for up to 35 years to look for biomarkers of later development of leukemia. Dr. Petrick found metabolites at birth that were predictive of developing childhood leukemia years later and that point to maternal and neonatal nutrition as potential risk factors.
