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.
