Lead is used to soften plastic, but can break down with the plastic to form dust which children may inhale, according to PIRG. In August of 2009, regulations were passed that said children's toys and products could not contain more than 300 ppm of lead. This threshold was lowered to 100 ppm in 2011, but existing inventories that may have met the older limit were still allowed to be sold.
PIRG said this Morphobot toy from GreenBrier International Inc. violates the current 100 ppm limit because it tested at 180 ppm of lead.
