Vintage toys are still in use today by some families, unaware that they may pose a health risk to their children as many older toys frequently contain toxic heavy metals, particularly lead and cadmium, and in concentrations that exceed current regulations. Degradation of these toys through time release small plastic particles, paint flakes, embedded metals or metal compounds, exposing any that may come in contact with them. Many older toys before 1978 were cast in lead or decorated with lead paint, but it wasn't until 2011 when accessible parts of toys was reduced to 100 parts per million, or 90 parts per million in paint or similar surface coatings. Some toys that were tested were barbies, little people sets, and my little pony figures, where pigments appeared to be the major culprit containing these toxins. Although many countries have restrictions now on the acceptable levels of toxins in toys, some imported toys are still exceeding these levels and are being distributed to the public.
