1. Annual Meeting, June 15-16 2015, Istanbul, Turkey Use of CHASE assessment tool with EMODNet Chemistry data EMODnet Chemistry Martin M. Larsen, Aarhus University Jesper H. Andersen, Tore Høgåsen NIVA Denmark

2. Annual Meeting, June 15-16 2015, Istanbul, Turkey Test run with all Danish data: Current status # data“good”“modererate”“bad” Water (not shown) 138 00 Sediments 6247132 Biota 1129958 Biological-effects 15960

3. Annual Meeting, June 15-16 2015, Istanbul, Turkey The CHASE model: What is CHASE For each contaminant measured, calculate the ratio to a threshold value (CR): For each substance group, calculate the Contaminant Score (CS): Contaminant scores was collected for water, biota, sediment and biological effects

5. Annual Meeting, June 15-16 2015, Istanbul, Turkey The CS for each Data type: Sediment Biota Bio. Marker

6. Annual Meeting, June 15-16 2015, Istanbul, Turkey The CS for each Data type: All together

9. Annual Meeting, June 15-16 2015, Istanbul, Turkey So what happened: Combining sediment, biota and biological effects Better geographical coverage Sediment and Biological effect data available for open sea Easy to include water data Only works if Threshold values are comparable ! Several stations can be included in each ”assessment unit” (typically 20x20 km grid coastal)

10. How to procede: Aggree on substances and thresholds (sea-wise) Currently Cd, Pb, Hg, PAHs, TBT others ? EU EQS limits ”natural” for EU areas (Baltic, North Sea), combined with OSPAR/HELCOM assessment criteria Is the classification suggested ok or use other limits? 0,5 (High)– 1 (Good) – 5 (Poor) – 10 (Bad) Include local/national limits for other areas/parameters And when it all have been integrated… Decide if combined CHASE results can be DIVA’ed Annual Meeting, June 15-16 2015, Istanbul, Turkey Planning for the last year
