Sadly, I have read about a number of young athlete deaths that have a connection to artificial turf. This ‘crumble’ does appear to have carcinogenic agents in it. And athletes are frequently down on the turf inhaling whatever has been disturbed from the turf. I do believe there should be a study, cataloging the deaths and comparing the type of ‘crumble’ used in the turf. It's the only way to learn and prevent possible harm to our kids. And if the study finds ‘no harm’, then so be it. Just don't let the ‘crumble’ makers fund the study.

Chemicals are also used to control weeds and insects in playing fields that have real grass, so I’m not sure they would be all that much safer.

The ‘crumble’ is old tires, with the exception of some fields with a white crumble called ‘Nike Grind’ - which is the material used on the soles of shoes.

I suppose the actual inhalation of the crumble could cause a problem.

But nothing in life is risk free.
