Communication from the Commission on the results of the risk evaluation of chlorodifluoro-
methane, bis(pentabromophenyl)ether and methenamine and on the risk reduction strategy for the
substance methenamine

(Text with EEA relevance)

(2008/C 131/04)

Council Regulation (EEC) No 793/93 of 23 March 1993 on the evaluation and control of the risks of
existing substances (1) involves the data reporting, priority setting, risk evaluation and, where necessary,
development of strategies for limiting the risks of existing substances.

In the framework of Regulation (EEC) No 793/93, the following substances have been identified as priority
substances for evaluation in accordance with Commission Regulations (EC) No 1179/94 (2) and (EC)
No 2268/95 (3) respectively concerning the first and the second list of priority substances as foreseen under
Regulation (EEC) No 793/93:

— chlorodifluoromethane,

— bis(pentabromophenyl)ether,

— methenamine.

The rapporteur Member States designated pursuant to those Regulations have completed the risk evaluation
activities with regard to man and the environment for those substances in accordance with Commission
Regulation (EC) No 1488/94 of 28 June 1994 laying down the principles for the assessment of risks to man
and the environment of existing substances (4) and have suggested a strategy for limiting the risks in accord-
ance with Regulation (EEC) No 793/93.

The Scientific Committee on Toxicity, Ecotoxicity and the Environment (SCTEE) and the Scientific Committee
on Health and Environmental Risks (SCHER) respectively have been consulted and have issued an opinion
with respect to the risk evaluations carried out by the rapporteurs. These opinions can be found on the
website of the Scientific Committees.

Article 11(2) of Regulation (EEC) No 793/93 stipulates that the results of the risk evaluation and the recom-
mended strategy for limiting the risks shall be adopted at Community level and published by the Commis-
sion. This Communication provides the results of risk evaluations (5) of chlorodifluoromethane, bis
(pentabromophenyl)ether and methenamine and the strategy for limiting the risks for methenamine.

The results of the risk evaluation and the strategy for limiting the risks set out in this communication are in
accordance with the opinion of the Committee set up pursuant to Article 15(1) of Regulation (EEC)
No 793/93.

Classification (1):

The risk assessment is based on current practices related to the life-cycle of the substance produced in or imported into
the European Community as described in the risk assessment forwarded to the Commission by the Member State
Rapporteur.

The risk assessment has, based on the available information, determined that in the European Community the substance
is mainly used as raw material feedstock for other chemicals such as fluoropolymers and as end product predominantly as
working fluid in vapour compression refrigeration cycles.

Other uses are foam blowing with HCFC-22 which has been banned since 1 January 2004 (2). Emissions deriving from
this use are not considered in the risk assessment.

RISK ASSESSMENT

A. Human health

The conclusion of the assessment of the risks to

WORKERS, CONSUMERS and HUMANS EXPOSED VIA THE ENVIRONMENT

is that there is at present no need for further information and/or testing or for risk reduction measures beyond those
which are being applied. This conclusion is reached because:

— the risk assessment shows that risks are not expected. Risk reduction measures already being applied are considered

sufficient.

The conclusion of the assessment of the risks to

HUMAN HEALTH (physico-chemical properties)

is that there is at present no need for further information and/or testing or for risk reduction measures beyond those
which are being applied. This conclusion is reached because:

— the risk assessment shows that risks are not expected. Risk reduction measures already being applied are considered

sufficient.

B. Environment

The conclusion of the assessment of the risks to the

ATMOSPHERE, AQUATIC ECOSYSTEM and TERRESTRIAL ECOSYSTEM

is that there is at present no need for further information and/or testing or for risk reduction measures beyond those
which are being applied. This conclusion is reached because:

— the risk assessment shows that risks are not expected. Risk reduction measures already being applied are considered

sufficient.

The risk assessment is based on current practices related to the life-cycle of the substance produced in or imported into
the European Community as described in the risk assessment forwarded to the Commission by the Member State
Rapporteurs (1).

The risk assessment has, based on the available information, determined that in the European Community the substance
is mainly used as a flame retardant additive in the manufacture of polymers, mainly for use in electrical equipment, and
drapery and upholstery textiles. Other minor uses reported are as a flame retardant additive in styrenic rubbers, polycar-
bonates, polyamides and terephthalates and in hot melt adhesives.

It was not possible to obtain information on the use of the total volume of substance produced in or imported into the
European Community, therefore, some uses may exist which are not covered by this risk assessment.

RISK ASSESSMENT

A. Human health

The conclusion of the assessment of the risks to

WORKERS

is that there is a need for further information and/or testing. This conclusion is reached because:

— there is a need for better information to adequately characterise the risks regarding developmental neurotoxic effects

of the substance.

The information requirements are:

— a further developmental neurotoxicity study in mice or rats.

The conclusion of the assessment of the risks to

CONSUMERS

is that there is at present no need for further information and/or testing or for risk reduction measures beyond those
which are being applied already.

This conclusion was reached in the risk assessment report because consumer exposure was considered negligible. While
recent information indicates that consumers may be exposed to bis(pentabromophenyl)ether released from consumer
products, this exposure has not yet been quantified and considered in the risk assessment based on the current hazard
profile available.

The conclusion of the assessment of the risks to

HUMANS EXPOSED VIA THE ENVIRONMENT

is that there is a need for further information and/or testing. This conclusion is reached because:

— there is a need for better information to adequately characterise human exposure and the risks regarding develop-

mental neurotoxic effects of the substance.

The information requirements are:

— a suitable human bio-monitoring programme, including breast milk and blood, and the need for a trend analysis with

annual reporting over a ten year time period,

— further developmental neurotoxicity study in mice or rats.

The conclusion of the assessment of the risks to

HUMANS HEALTH (physico-chemical properties)

is that there is at present no need for further information and/or testing or for risk reduction measures beyond those
which are being applied. This conclusion is reached because:

— the risk assessment shows that risks are not expected. Risk reduction measures already being applied are considered

sufficient.

B. Environment

The conclusion of the assessment of the risks to the

AQUATIC AND TERRESTRIAL ECOSYSTEM

is that there is a need for further information and/or testing. This conclusion is reached because:

— there is a need for better information to adequately characterise the concerns regarding the persistent, bioaccumulative

and toxic properties of the substance.

The information requirements are:

— environmental monitoring, programme including birds, sewage sludge, sediment, and air to establish the trends in
levels of contamination for the substance and its more toxic and bioaccumulative degradation products, with annual
reporting over a 10 year time period.

The conclusion of the assessment of the risks to the

ATMOSPHERE

is that there is at present no need for further information and/or testing or for risk reduction measures beyond those
which are being applied. This conclusion is reached because:

— the risk assessment shows that risks are not expected. Risk reduction measures already being applied are considered

sufficient.

RISK ASSESSMENT

A. Human health

The conclusion of the assessment of the risks to

WORKERS

is that there is a need for specific measures to limit the risks. This conclusion is reached because of:

— concerns for skin sensitisation as a consequence of dermal exposure arising in all scenarios,

— concerns for systemic toxicity as a consequence of repeated dermal exposure arising from formulation of phenolic

resin systems,

— concerns for developmental toxicity as a consequence of repeated dermal exposure arising from formulation of
phenolic resin systems, from production of fuel tablets, and from production of formulations used in corrosion
prevention and as photo chemicals.

For WORKERS

STRATEGY FOR LIMITING RISKS

The legislation for workers' protection currently in force at Community level is generally considered to give an adequate
framework to limit the risks of the substance to workers to the extent needed and shall apply.

For CONSUMERS

The existing legislative measures for the protection of consumers, in particular the provisions under Council Directive
76/768/EEC ( 1) as regards cosmetics and Directive 2001/95/EC as regards products, are considered sufficient to address
identified risks to consumers.

(1) A Commission Proposal for a recast of the Directive 76/768/EEC was adopted on 5 February 2008.
