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) ECB INFODAYS Zagreb, Croatia, 11-13 December 2006
Priority Setting Existing Substances 140 Priority Substances > 2000 HPVCs > 100.000 EINECS substances ECB INFODAYS Zagreb, Croatia, 11-13 December 2006
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. ECB INFODAYS Zagreb, Croatia, 11-13 December 2006
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 ECB INFODAYS Zagreb, Croatia, 11-13 December 2006

Limitations of EUSES • A model is always a “cartoon of reality” • Chemical risk policy of the EC • Model analysis and validation limited • Expertise of user is important • data evaluation (“garbage in - garbage out”) • interpretation of results ECB INFODAYS Zagreb, Croatia, 11-13 December 2006

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 ECB INFODAYS Zagreb, Croatia, 11-13 December 2006
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 ECB INFODAYS Zagreb, Croatia, 11-13 December 2006
