The European Chemicals Agency’s Risk Assessment and Socio-Economic Analysis Committee received a report from France that proposed lead and fumaric acid in specific products such as jewelry, furniture and footwear for production and/or distribution in the European market. The dimethyl ester content is limited.

With respect to lead, the French report (referred to as Annex XV) has proposed limiting the content of lead and its compounds in jewelry to the regulations on the registration, evaluation, authorization and restriction of chemicals.

This proposed restriction will prohibit the production and/or sale in Europe of all jewellery (precious and fashionable, adult and children's jewelry) with a migration speed greater than 0.09 micrograms per square centimetre per hour.

French authorities worry that children may face serious health problems. Especially when they suck or ingest jewellery, their central nervous system suffers from exposure to lead.
