General Process
• Priority setting:
– Production volume only, e.g. OECD HPV Chemicals
Programme (currently 5235 substances on OECD
HPV List)
– Risk based priority setting system e.g. ESR
(EURAM), PBT Chemicals, WFD,
– According to use only (BPD)
Priority Setting Existing Substances
140
Priority
Substances
> 2000 HPVCs
> 100.000 EINECS substances
Priority lists:
factors which should be taken into account
• the effects of the substance to man or the environment;
• the exposure of man or the environment to the substance;
• the lack of data on the effects of the substance on man and the
environment;
• work already carried out in other fora;
• other Community legislation and/or programmes relating to
dangerous substances.
EURAM using IUCLID data
Substance may obtain high scores if, for example
– it is produced in large volumes
– is used in a dispersive manner
– persists in the environment
– is highly toxic to humans, animals or plants
– has long term/chronic effects
– is carcinogenic, mutagenic or toxic to reproduction (CMR)
– little is known about its properties, use or effects

Introduction of :
Instrument for the quantitative assessment of the
risks posed by new and existing chemical
substances and biocides to man and the
environment.
EUSES is a coordinated effort of:
• EU Member States
• The European Commission (DG ENV)
• The European Chemicals Bureau (JRC-ECB)
• The European Chemical Industry

Limitations of EUSES
• Chemical risk policy of the EC
• A model is always a “cartoon of reality”
• Model analysis and validation limited
• Expertise of user is important
– data evaluation (“garbage in - garbage out”)
– interpretation of results
Tools for Risk Assessment of Chemicals
IUCLID4
International Uniform Chemical Information Database
TGD
Technical Guidance Documents
EUSES
Available to download for free at ECB website:
http://ecb.jrc.it/documents
What have we learned from using the TGD?
• THEOREM:
– Where there is “Clear guidance” there is less discussion
– Where there is “Some guidance” there is more discussion
– Where there is “Little Guidance” there is lots of discussion
• CORROLARY:
– The more discussion the more room for inconsistent decisions
and the slower the decision making
TGD and EUSES under REACH ?
• Basic principles will apply
• Industry will have to demonstrate safe use of chemicals
through Risk Assessment
• Manufacturers/Importers vs (Downstream) Users: who
does what
• Challenge to develop appropriate guidance
• Use of QSARs and category approaches
