9. What further information is needed on environmental risks of dental amalgams?
The SCHER opinion states:
3.4 Question 4
If the Committee under its work finds out that more information is needed, for one or more questions, the Committee is asked to provide a detailed list on what this kind of information is needed to carry out the tasks.
From the responses given in the previous sections, it is clear
that the information presently available does not allow to
comprehensively assessing the environmental risks and indirect
health effects from the use of
dental amalgam in the
Member States of the EU 27.
To allow this type of assessment, the following information is
- More specific information on possible
regional-specific differences in the use, release and fate
of Hg originating from
dental amalgam. This
includes detailed quantitative information on the use and
release pattern in all EU 27 countries, possible
country-specific abatement measures, and differences in the
fate of mercury due to
regional-specific municipal wastewater treatment and sludge
- A comprehensive and updated data compilation on the
effects to humans and (various) environmental species of Hg
- A more comprehensive evaluation of atmospheric
emissions and further deposition of
crematoria, taking into account EU-wide practices and
possible region-specific local scenarios.
- A comprehensive literature review of the
bioaccumulation and biomagnification of
different EU conditions.
- A detailed comparison of the relative contribution of
dental Hg to the overall
mercury pool –
originating from intended and non-intended Hg – in the
