Comprehensive multipathway risk assessment of chemicals associated with recycled ("crumb") rubber in synthetic turf fields

Michael K.Peterson, et al., November 2017

Abstract

Background: Thousands of synthetic turf fields in the US are regularly used by millions of individuals (particularly children and adolescents). Although many safety assessments have concluded that there are low or negligible risks related to exposure to chemicals found in the recycled rubber used to make these fields, concerns remain about the safety of this product. Existing studies of recycled rubber's potential health risks have limitations such as small sample sizes and limited evaluation of relevant exposure pathways and scenarios.

Objective: Conduct a comprehensive multipathway human health risk assessment (HHRA) of exposure to chemicals found in recycled rubber.

Synthetic Turf and Crumb Rubber: Investigation of Reported Cancer among Soccer Players in Washington State

January 2017
The primary objectives of the investigation were to: Determine whether the number of cancer diagnoses among the soccer players reported to the project team was higher than would be expected if rates of cancer among these soccer players were similar to rates among all Washington residents of the same ages. Describe individuals reported to the project team in terms of their demographics, factors related to cancer and history of playing soccer and other sports.

Playing Sports on Synthetic Turf Fields with Rubber Granulate is Safe

Publication date: December 20, 2016
Modification date: January 31, 2017

New research by the Dutch National Institute for Public Health and the Environment (RIVM) shows it is safe for people to play sports on synthetic turf fields with an infill of rubber granulate. Rubber granulate contains numerous substances which were found to be released from the granulate in very low quantities. This is because the substances are more or less ‘enclosed’ in the granulate, which means that the effect of these substances on human health is virtually negligible.

Information Sheet: Recycled Rubber Cancer Cases

Gradient, October 2016
The Concern: Amy Griffin, associate head coach for the University of Washington women's soccer team, "has been informally tracking American soccer players with cancer since 2009" (1). She has identified 220 cases to date, 166 of them soccer players. The two most frequent cancer diagnoses are lymphoma and leukemia. The diagnoses date back to 1994, with the ages 5-24 specifically mentioned (2). The concern is that exposure to chemicals in recycled rubber has caused the identified cancer cases.
