For years we've known not to play with peeled paint chips; now, we know not to eat the turf. The US Consumer Product Safety Commission recently announced an investigation potential hazardous levels of lead in artificial turf fields across the country.

Two fields in New Jersey were closed this week after elevated levels of lead were found during an unrelated investigation. The source is likely from lead chromate that is used as pigment and to prevent fading. While the lead could become airborne through wear on the surfaces, further studies are necessary to assess the actual risk.
