An environmental watchdog group in New Jersey recently issued a warning regarding excessive amounts of lead in artificial turf.
The warning has reportedly been issued to some of the largest manufacturers and sellers of artificial turf throughout the country.
The group, the Center for Environmental Health, has warned the companies that they will file suits unless the products are recalled and reformulated.
The group issued the warning after New Jersey officials found high levels of lead in some synthetic surfaces.
After the findings, federal authorities suggested leading testing be done on all sports fields.
A lab hired to do the testing went beyond sports fields and also tested indoor and outdoor carpeting, artificial lawns and playground grass.
Excessive amounts of lead were found in all the areas that were tested.
The group reported that the amount of lead exceeded 600 parts per million, which is the maximum amount of lead permitted in paint.
