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 comprehensive Risk Assessment Report forwarded to the Commission by
the Member State Rapporteur (2). The risk assessment has, based on the available information, determined that in the
European Community the substance is mainly used as an intermediate for synthesis of industrial chemicals, pharmaceuti-
cals and pesticides, and in the manufacturing of photographic film. Other uses include as a solvent in various extraction
processes and in research and analytical laboratories. 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.

The risk assessment has identified other sources of exposure of the substance to man and the environment, in particular,
the substance is produced during biomass burning and is present in automobile exhaust, which do not result from the
life-cycle of the substance produced in or imported into the European Community. The assessment of the risks arising
from these exposures are not part of this risk assessment. The comprehensive Risk Assessment Reports as forwarded to
the Commission by the Member State Rapporteur does however provide information about these risks.

RISK ASSESSMENT

A. Human health

The conclusions of the evaluation 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 general systemic toxicity as a consequence of dermal exposure arising from use as a solvent and as an

intermediate.

The conclusions of the evaluation of the risks to

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.

(1) The classification of the substances is established by Commission Directive 2000/32/EC of 19 May 2000 adapting to technical
progress for the 26th time Council Directive 67/548/EEC on the approximation of the laws, regulations and administrative provisions
relating to the classification, packaging and labelling of dangerous substances (OJ L 136, 8.6.2000, p. 1).

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 conclusions of the evaluation of the risks to the environment for

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 related to the environmental spheres mentioned above are not expected. Risk

reduction measures already being applied are considered sufficient.

The conclusions of the evaluation of the risks to the environment for

AQUATIC ECOSYSTEM and TERRESTRIAL ECOSYSTEM

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

— concerns for the aquatic and terrestrial ecosystems as a consequence of exposure arising from use of the substance in

the pharmaceutical industry.

The conclusions of the evaluation of the risks to the environment for

MICRO-ORGANISMS IN THE SEWAGE TREATMENT PLANT

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

— concerns for effects on sewage treatment plants as a consequence of exposure arising from the use of the substance

in the pharmaceutical industry.

STRATEGY FOR LIMITING RISKS

The risk assessment has identified other sources of acetonitrile emissions (eg burning of fossil fuels). This is outside the
scope of Council Regulation (EEC) 793/93 and has not been considered in the Risk Reduction Strategy.

for WORKERS

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

Within this framework it is recommended:

— to consider

revising the current occupational exposure limit value adopted under Commission Directive

91/322/EEC (1) to provide an indication that dermal exposure can make a contribution to the worker body burden.

for ENVIRONMENT

— that the European Commission should consider the inclusion of acetonitrile in the priority list of Annex X to
Council and Parliament Directive 2000/60/EC (2) (Water Framework Directive) during the next review of this Annex.

— to facilitate permitting under Council Directive 96/61/EC (1)

(Integrated Pollution Prevention and Control) this
substance should be included in the ongoing work to develop guidance on ‘Best Available Techniques’ (BAT). It is
recommended that Member States should carefully monitor the implementation of BAT by permitting and report
any important developments to the Commission in the framework of the exchange of information on BAT.

— local emissions to the environment should, where necessary, be controlled by national rules to ensure that no risk

for the environment is expected.

the European Community as described in the comprehensive Risk Assessment Report forwarded to the Commission by
the Member State Rapporteur (3).

The risk assessment has, based on the available information, determined that in the European Community the substance
is mainly used as an intermediate in the chemical industry for the production of polyacrylamide. Other uses are as on-
site preparation of polyacrylamide gels and as grouting agents. The main uses of polyacrylamide are in waste water treat-
ment, paper and pulp processing and mineral processing; minor uses include as cosmetic additives and as soil condi-
tioners. 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 conclusions of the evaluation of the risks to

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

— concerns for mutagenicity and carcinogenicity as a consequence of exposure arising from production of the
substance, use as an intermediate in the chemical industry for the production of polyacrylamide, use of polyacryla-

— concerns for neurotoxicity and reproductive toxicity as a consequence of exposure arising from the small and large

scale use of acrylamide based grouts.

The conclusions of the evaluation of the risks to

CONSUMERS

— is that risks can not be excluded at any exposure, as the substance is identified as a non-threshold carcinogen. The
adequacy of existing controls and the feasibility and practicability of further specific measures should be considered.
However, the risk assessment indicates that risks are already low. This should be taken into account when consid-
ering the adequacy of existing controls and the feasibility and practicability of further specific risk reduction
measures.

The conclusions of the evaluation of the risks to

HUMANS EXPOSED VIA THE ENVIRONMENT

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

— concerns for neurotoxicity, reproductive toxicity, mutagenicity and carcinogenicity as a consequence of exposure

resulting from the use of acrylamide based grouts in large scale construction applications.

In addition to the conclusion given above, risks cannot be excluded considering the remaining uses, as the substance is
identified as a non-threshold carcinogen. The adequacy of existing controls and the feasibility and practicability of

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

— concerns for the aquatic ecosystem as a consequence of exposure arising from the use of acrylamide based grouts in
construction applications, and to indirect exposure of other organisms through contaminated water from the same
use.

The conclusion of the assessment of the risks to the

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

— concerns for use of acrylamide-based grouts in construction applications. The information and/or testing requirement

is:

— information to refine the risk evaluation for the environment.

The need to obtain this information was re-evaluated in light of the risk reduction strategy and is no longer required
(see section II Strategy for limiting risks).

STRATEGY FOR LIMITING RISKS

for HUMAN HEALTH and the ENVIRONMENT

It is recommended:

— to consider at Community level marketing and use restrictions in Council Directive 76/769/EEC (1) for the use of

acrylamide (2) in grouts for small and large-scale applications,

— further work may be necessary to determine if derogations can be justified,

— the marketing and use restrictions proposed will eliminate the need for more information to refine the risk evalua-

tion for the environment.

for WORKERS

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

Within this framework it is recommended:

— to establish at community level occupational exposure limit values for acrylamide.

for CONSUMERS

— The existing legislative measures for consumer protection, in particular the provisions under Directive 76/769/EEC
(Marketing and Use Directive) as regards substances that are carcinogenic, mutagenic and toxic to reproduction
(CMR substances), and Directive 2001/95/EC of the European Parliament and of the Council (general product
safety) (3) as regards products which are considered sufficient to address the risks identified.

The risk assessment has identified other sources of exposure to the substance, relevant for man and the environment,
which do not result from the life cycle of the substance produced in or imported into the European Community, in par-
ticular, the substance is produced during combustion of fossil fuels. The assessment of the risks arising from these expo-

STRATEGY FOR LIMITING RISKS

The risk assessment has identified other sources of acrylonitrile emissions (e.g. burning of fossil fuels). This is outside the

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 the extent needed and shall apply.

Within this framework it is recommended:

— to establish at community level occupational exposure limit values for Acrylonitrile

for CONSUMERS and HUMANS EXPOSED VIA THE ENVIRONMENT

— The existing legislative measures for the protection of consumers and humans exposed via the environment, in par-
ticular the provisions under the Directive 76/769/EEC (marketing and use Directive) as regards CMR substances,
Directive 2001/95/EC (general product safety) as regards products, and Directive 96/61/EC (integrated pollution
prevention and control) are considered sufficient to address the risks identified.

for the ENVIRONMENT

— to facilitate permitting under Directive 96/61/EC (integrated pollution prevention and control) this substance should
be included in the ongoing work to develop guidance on ‘best available techniques’ (BAT). It is recommended that
Member States should carefully monitor the implementation of BAT by permitting and report any important devel-
opments to the Commission in the framework of the exchange of information on BAT,

— local emissions to the environment should, where necessary, be controlled by national rules to ensure that no risk

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

The risk assessment has, based on the available information, determined that in the European Community the substance
is mainly used as an intermediate in the production of poly-acrylates. Other uses are as an ingredient in adhesives and
its occurrence as a residual monomer in adhesives, paints, binding agents, printing inks, sanitary towels, panty-liners and
nappy pants. Polyacrylates are mainly used as co-builders in phosphate free washing agents, in flocculating agents and
for treatment of drinking and waste water. 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.

The risk assessment has identified other sources of exposure to the substance, relevant for man and the environment, in
particular, during the use of acrylate based grouting agents, as a decomposition product during the production of
printed circuit boards and during the removal of paints using gas flames, which do not result from the life-cycle of the
substance produced in or imported into the European Community. The assessment of the risks arising from these expo-
sures are part of 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 specific measures to limit the risks. This conclusion is reached because of:

— concerns for respiratory tract irritation and corrosivity as a consequence of single inhalation exposure arising from
production and processing, production of adhesives containing the substance and use of adhesives containing the
substance,

— concerns for local effects as a consequence of repeated inhalation exposure arising from production of adhesives

containing the substance and use of adhesives containing the substance,

— concerns for general systemic toxicity as a consequence of repeated inhalation exposure arising from production and

use of adhesives containing the substance.

The conclusion of the assessment of the risks to

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

B. Environment

The conclusions of the evaluation of the risks to the environment for

AQUATIC ECOSYSTEM

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

sufficient.

The conclusion of the assessment of the risks to

MICRO-ORGANISMS IN THE SEWAGE TREATMENT PLANT

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 risk to municipal waste water treatment plants
as a consequence of exposure from the use of the substance for wet polymerisation including the production of
super absorber polymers.

The information and/or test requirements are

— Further data reflecting integrity of native ciliate populations in sewage.

STRATEGY FOR LIMITING RISKS

for WORKERS

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 the extent needed and shall apply.

Within this framework it is recommended:

— to establish at community level occupational exposure limit values for acrylic acid.

— that employers using adhesives containing acrylic acid should take note of the practical non-binding guidance, to be
developed by the Commission as foreseen under Article 12(2) of Council Directive 98/24/EC (1) (chemical agents
Directive), and of any sector specific guidance developed at national level based on this guidance.

for ENVIRONMENT

it is recommended that:

for Acrylic Acid released from chemical grouts:

— to establish a harmonised European testing and assessment scheme for chemical grouts,

— to regulate general conditions for use of chemical grouts at EU level, including requirements on comprehensive
training of planners and field personnel, whereas local aspects should be considered by the respective local supervi-
sory authorities,

— local emissions to the environment should, where necessary, be controlled by national rules to ensure that no risk

for the environment is expected;

for Acrylic Acid used in wet polymerisation processes at downstream user sites (processing capacity > 500 t/a) and in
SAP production:

— that the European Commission should consider the inclusion of acrylic acid in the priority list of Annex X to Direc-
tive 2000/60/EC (water framework Directive) during the next review of this Annex and should consider measures
such as harmonised requirements for prior authorisation of discharges and emissions into water for the respective
plants,

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 comprehensive Risk Assessment Report forwarded to the Commission by
the Member State rapporteur (2).

The risk assessment has, based on the available information, determined that in the European Community the substance
is mainly used as an intermediate in the polymer industry. The major uses of 1,3-butadiene are in the manufacture of
synthetic rubber such as styrene-butadiene rubber (SBR) and polybutadiene rubber, thermoplastic resins such as acryloni-
trile-butadiene-styrene (ABS), and styrene-butadiene latex. It is also used as a chemical intermediate in the production of
neoprene for automotive and industrial rubber goods, in the production of methylmethacrylate-butadiene-styrene (MBS)
polymer, which is used as a polyvinyl chloride (PVC) reinforcing agent, and for producing adiponitrile, a nylon
precursor. 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 conclusions of the evaluation 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 mutagenicity and carcinogenicity as a consequence of exposure arising from production and use as an

intermediate in the polymer industry.

The conclusions of the evaluation of the risks to

CONSUMERS and HUMANS EXPOSED VIA THE ENVIRONMENT

is that there is a need to limit the risks. This conclusion is reached because:

— risks can not be excluded for all exposure scenarios, as the substance is identified as a non-threshold carcinogen. The
adequacy of existing controls and the feasibility and practicability of further specific measures should be considered.
However, the risk assessment indicates that risks are already low. This should be taken into account when consid-
ering the adequacy of existing controls and the feasibility and practicability of further specific risk reduction
measures.

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 the extent needed and shall apply.

Within this framework it is recommended:

— to establish at community level occupational exposure limit values for methyl methacrylate,

— that employers using methyl methacrylate for the uses identified as a concern in the risk assessment (part I) should
take note of the practical non-binding guidance to be developed by the Commission as foreseen under Article 12(2)
of Directive 98/24/EC (chemical agents Directive), and of any sector specific guidance developed at national level
based on this guidance;

for ENVIRONMENT

for Methyl methacrylate used in wet polymerisation processes at downstream user sites (processing capacity > 5000 t/a)
it is recommended:

— that the European Commission should consider whether to include methyl methacrylate on the priority list of Annex
X to Directive 2000/60/EC (water framework Directive) during the next review of this Annex and should consider
measures such as harmonised requirements for prior authorisation of discharges and emissions into water for the
respective plants.

— to facilitate permitting under Directive 96/61/EC (integrated pollution prevention and control) this substance should
be included in the ongoing work to develop guidance on ‘best available techniques’ (BAT). It is recommended that
Member States carefully monitor the implementation of BAT by permitting and report any important developments
to the Commission in the framework of the exchange of information on BAT,

— local emissions to the environment should, where necessary, be controlled by national rules to ensure that no risk

for the environment is expected.

The risk assessment is based on current practices related to the lifecycle of the substance produced in or imported into
the European Community as described in the comprehensive Risk Assessment Report forwarded to the Commission by
the Member State rapporteur (2).

The risk assessment has, based on the available information, determined that in the European Community the substance
is mainly used as an intermediate for synthesis of other chemicals, in solvents, and adhesives, paints, lacquers, varnishes
and in the mineral oil, fuel and polymer industries. Other uses reported are in the pulp, paper and board industry,
textile industry, agricultural industry and electrical and electronic industry.

The risk assessment has identified other sources of exposure of the substance to man and the environment, in particular
the use and combustion of petroleum products, which do not result from the life-cycle of the substance produced in or
imported into the European Community. The assessment of the risks arising from these exposures is not part of this risk
assessment. The comprehensive Risk Assessment Reports as forwarded to the Commission by the Member State Rappor-
teur does however provide information that could be used to assess these risks.

RISK ASSESSMENT

A. Human health

The conclusions of the evaluation 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 acute toxicity as a consequence of dermal exposure arising from spraying painting or the use of adhe-

sives,

— concerns for acute toxicity (headache, dizziness, feeling of intoxication, sleepiness and impaired functional perfor-
mance) as a consequence of inhalation exposure arising from production and use as an intermediate, production of
products containing the substance and use of products containing the substance,

— concerns for eye irritation as a consequence of exposure arising from production of products containing the
substance and use of products containing the substance in the sectors of manual cleaning, use of adhesives, printing
and painting (mechanical coating),

— concerns for general systemic toxicity as a consequence of inhalation exposure arising from production of products
containing the substance and use of products containing the substance in the sectors of manual cleaning, use of
adhesives, printing and painting (mechanical coating),

(1) The classification of the substance is established by Commission Directive 91/325/EEC of 1 March 1991, adapting to technical
progress for the 12th time Council Directive 67/548/EEC on the approximation of the laws, regulations and administrative provisions
relating to the classification, packaging and labelling of dangerous substances (OJ L 180, 8. 7. 1991, p. 1).

The conclusions of the evaluation of the risks to

CONSUMERS

1.

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

— concerns for acute toxicity (headache, dizziness, feeling of intoxication, sleepiness and impaired functional perfor-
mance) and eye irritation as a consequence of inhalation exposure or eye exposure to vapours arising from spray
painting and carpet laying.

2.

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

— concerns for effects on reproduction as a consequence of inhalation exposure.

The information and/or test requirement is:

— information on the relationship between the observed effects on reproduction and the duration of the exposure

leading to these effects.

The need to obtain this information was re-evaluated in light of the risk reduction strategy and is no longer required
(see section II Strategy for limiting risks).

The conclusions of the evaluation of the risks to

HUMANS EXPOSED VIA THE ENVIRONMENT

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

— concerns for effects on humans due to the contribution of commercial product toluene to the formation of ozone

and other harmful substances, i.e., smog formation.

The conclusion of the assessment of the risks to

HUMAN HEALTH (physicochemical properties)

substances, i.e. smog formation.

The conclusion of the assessment of the risks for

MICRO-ORGANISMS IN THE SEWAGE TREATMENT PLANT

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

— concerns for sewage treatment plants as a consequence of exposure arising from processing of the substance as well

as in the use sectors of industry use as basic chemicals.

STRATEGY FOR LIMITING RISKS

The risk assessment has identified other sources of toluene emissions (e.g. gasoline and crude oil). This is outside the
scope of Regulation (EEC) No 793/93 and has not been considered in the risk reduction strategy.

for WORKERS

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 the extent needed and shall apply.

Within this framework it is recommended:

— that the Commission Scientific Committee on Occupational Exposure Limits (SCOEL) review the new information

contained in the risk assessment report and recommend whether there is a need to revise the current OEL.

for CONSUMERS

It is recommended:

— to consider at Community level marketing and use restrictions in Directive 76/769/EEC for the substance as such or

in preparations for use in adhesives and spray paint.

— The marketing and use restrictions proposed will eliminate the need for more information on reproduction as a

consequence of inhalation exposure.

for ENVIRONMENT and HUMANS EXPOSED VIA THE ENVIRONMENT

It is recommended:

— that the European Commission should consider the inclusion of toluene in the priority list of Annex X to Directive
2000/60/EC (water framework Directive) during the next review of this Annex but that, in the meantime, toluene
should be considered as a relevant List II substance in Council Directive 76/464/EEC (1) on pollution caused by
certain dangerous substances discharged into the aquatic environment of the Community, thus requiring the estab-
lishment of national quality objectives, monitoring and eventual reduction measures, as to ensure that concentrations
in surface water systems do not exceed the quality objective,

(1) OJ L 129, 18.5.1976, p. 23.

Member States should carefully monitor the implementation of BAT by permitting and report any important devel-
opments to the Commission in the framework of the exchange of information on BAT,

The risk assessment is based on current practices related to the lifecycle of the substance produced in or imported into
European Community as described in the comprehensive Risk Assessment Report forwarded to the Commission by the
Member State rapporteur (3).

The risk assessment has, based on the available information, determined that in the European Community the substance
is mainly used as an intermediate for synthesis of herbicides and as a process solvent in closed systems. Other uses
reported include as a solvent, dye carrier in textile industry, additive in dielectric fluids and corrosion inhibitor. It was
not possible to obtain information on the use of the total volume of substance produced in or imported into the Euro-
pean Community, therefore, some uses may exist which are not covered by this risk assessment.

The risk assessment has identified other sources of exposure of the substance to man and the environment, in particular,
from certain 1,2,4-trichlorobenzene containing dielectric fluids still in use in existing electrical equipment and environ-
mental formation of 1,2,4-trichlorobenzene as a decomposition product of other, more complex organo-chlorine
compounds, which do not result from the life-cycle of the substance produced in or imported into the European Com-
munity. The assessment of the risks arising from these exposures are not part of this risk assessment.

The comprehensive Risk Assessment Reports as forwarded to the Commission by the Member State rapporteur does
however provide information that could be used to assess these risks.

The risk assessment indicates that it should be further investigated if the substance should be considered in relation to
national or international programmes addressing persistent organic pollutants.
