1. Report Of further work on Prioritization 5th meeting WG-E

2. Start 4th WG-E meeting comments on Subgroup work:
JRC/UK proposal complementary to INERIS prioritisation exercise
JRC/UK proposal open to comment
Comments received from DK, SE, ECPA, CEFIC
Principles of prioritisation in general accepted (all comments)
Proposed PS: adding substances classified as being hazardous for aquatic environment R50-R53 (DK); some substance groups and substances (SE)
European representative-ness, but only SPIN-database keeps additional information on tonnage / use
Check data- availability for plant protection products, data have been provided by EU review reports
Sub-group of WG-E “Emission of Priority Substances” started work and may contribute
SPIN Database = database from Nordic countries
 So far (17/03/2009) JRC has not received new data from Subgroup-WG-E “Emissions of Priority Substances”

3. JRC Draft Universe of Chemicals
INPUT (external)
INERIS (INERIS data)
UK (UK data)
NORMAN (emerging substances)
European Parliament proposals
Substances / Substance groups proposed by SE
INPUT (JRC)
ClassLab (R50-R53)
Registration date of List of REACH pre-registered substances
Substance identification data from EINECS
Structures and substance identification data from JRC QSSAR databases Data compilation
Information provided by NORMAN projects = Network of reference laboratories, research centres and related organisations for monitoring of emerging environmental substances»
To the EINECS substances JRC has updated the list containing structural information for 72,561 chemicals and it is now available for download along with supporting information on the generation and quality control of structures
On substances groups, for some substances proper CAS number is missing
HPVC under REACH will be evaluated after 2010
Data merge by CAS, if available

4. Draft Universe of Chemicals - Results
CAS - merge
Number of records
total
1255
Source INERIS
897
Source not INERIS
358
Substance identification completed
1123
Organics (QSAR potentially for PBT assessment applicable)
992
No CAS available (mainly substance categories) 64
Note that the total number of substances (358) arriving form external proposals are higher than expected.
No CAS available for substances categories e.g. organotin compounds
Data available at  >
> WORKSHOP PRIORITISATION PS > UNIVERSE OF CHEMICALS

6. Draft Universe of Chemicals
Proposed next steps
Completion of substance identification
Proposal to group substances for prioritization (such like organic-tin-compounds, plant protection products
Integration of databases (such like footprint – hazard properties of plant protection products DSSTOX
Integration of QSAR to fill data gaps
Next meeting of Sub-group “Prioritization of substances”? (May, 2009)
Groups of substances according to an EU wide representativeness e.g. pesticides by chemical class and mode of action
DSSTOX Distributed Structure-Searchable Toxicity (DSSTox) Public Database Network is a US EPA database
