Where it has received a relatively good amount of related attention is in concerns over potential exposure to hazardous chemicals when recycled tire products, or “tire crumbs,” are used as ground cover for artificial turf playing fields. Most of that concern stemmed from reports of soccer goalies developing blood cancer when the 2015 FIFA Women’s World Cup was being played on artificial turf.
