The European Commission’s Scientific Committee on Health and Environmental Risks (SCHER) has proposed that the levels of Chromium (VI) available by migration from toys be further lowered.
The proposed values are:
- 0.0094 mg/kg for scraped-off toy materials;
- 0.0008 mg/kg for dry, (powder-like or pliable) toy materials; and
- 0.0002 mg/kg for liquid or sticky toy materials
These values are extremely low, and are in fact below the levels at which chromium (VI) can be measured in the laboratory. Chromium (VI) is a very difficult species to measure, and it is only in recent years that methods capable of separating the more toxic hexavalent form from the more common trivalent form have been developed.
There is a school of thought that instituting a limit value below that which can be measured should not happen and that it would be more sensible to have a limit value equivalent to the best available limit of quantification (LOQ), which can of course be lowered as advances in measurement capability develop.
