Toxicity of crumb rubber from artificial turf

Proceedings of the National Academy of Sciences

Researchers report that exposing chicken embryos, a model of higher vertebrate development, to pollutants leached from crumb rubber used in artificial turf infill led to embryonic mass loss and developmental malformations, particularly in the brain and cardiovascular system, as well as gene dysregulation in multiple biological pathways, suggesting the need to reexamine the potential toxicity of crumb rubber used in artificial turf such as playgrounds and athletic fields.
