1. Further population of metadata and data for contaminantsBy
Dick M.A. Schaap – Technical Coordinator
Roskilde - Denmark, 6th February 2018, Plenary Group meeting EMODnet Chemistry 3

2. Contaminants Approach for marine chemistry measurements
Continuation of approach of gathering and populating relevant measurements data into the SeaDataNet CDI Data Discovery and Access service with CDI metadata format and ODV data format; use of MIKADO and NEMO / Octopus tools
Focus on data concerning:
eutrophication (nutrients, chlorophyll and oxygen)
Contaminants
Micro marine litter
Geographical scope expanded with Barents Sea
Data scope expanded with riverine input of nutrients

3. Which contaminants?
Pharmaceuticals
In the 3 matrices: water, sediment, biota

4. Which contaminants – for biota?
In addition, there is a need to collect also following parameters specifically in biota:
o PCB’s
§ CB28 - 2,4,4'-trichlorobiphenyl
§ CB52 - 2,2',5,5'-tetrachlorobiphenyl
§ CB ,2',4,5,5'-pentachlorobiphenyl
§ CB ,3,3',4,4'-pentachlorobiphenyl
§ CB ,3',4,4',5-pentachlorobiphenyl
§ CB ,2',3,4,4',5'-hexachlorobiphenyl
§ CB ,2',4,4',5,5'-hexachlorobiphenyl
§ CB ,2',3,4,4',5,5'-heptachlorobiphenyl
§ TBSN+ - Tributyltin ion

5. Chemical substances for contaminants
In addition, there is a need to collect also following parameters specifically in biota:
o PBDE’s
§ PBDE28 - 2,4,4'-tribromodiphenyl ether
§ PBDE47 - 2,2',4,4'-tetrabromodiphenyl ether
§ PBDE99 - 2,2',4,4',5-pentabromodiphenyl ether
§ PBDE ,2',4,4',6-pentabromodiphenyl ether
§ PBDE ,2',4,4',5,5'-hexabromodiphenyl ether
§ PBDE ,2',4,4',5,6'-hexabromodiphenyl ether
o PFOS - perfluorooctanyl sulphonic acid
o DDT
§ DDEPP - DDE (p,p')
o BAP – Benzo(a)pyrene
o Antifoulants
§ TBTIN - Tributyltin (TBT)
§ TBSN+ - Tributyltin ion

6. CDI population and maintenance by partners for contaminants:
Gathering of local data and metadata by partners
Mapping and local editing activities
Compiling and validating batches of metadata
Submission to MARIS for import and validation into the operational CDI directory
Maintaining the coupling table between CDI metadata and local data

7. Extra efforts required by data providers for:
Including additional quality information in CDI
Including indication ‘Monitoring <-> Research’
Ensuring coherence of the CDI – ODV relations
Ensuring validity of ODV files => Use OCTOPUS and ODV software for checking ODV files
Do these checks and extra’s for new entries
Review also existing CDIs and ODVs
Follow the inventory as provided as part of the proposal
From now till June 2018 for contaminants data
