  1. COHIBA preliminary results for implementation HELCOM BSAP Ms. Eva Brorström-Lundén, IVL Swedish Environmental Research Institute 32rd Meeting of the Helsinki Commission 9-10 March 2011, Helsinki, Finland

  2. COHIBA deliveries for BSAP implementation

  3. Baltic wide screening of discharges • Coordinated sampling programme in 8 EU countriesfor screening the sources of 11 BSAP substances/ substance groups • WWTPs, treated effluents; sewage sludge; landfill leachate and storm water • HELCOM BSAP substances or substance groups observed • All 11 priority substances observed in majority of the samples • Notable seasonal variations in effluent quality • No remarkable differences observable between industrial and municipal effluents • Whole effluent toxicity testing an excellent tool to assess the overall ecotoxicity of effluents • Acute and chronic toxicity like also high hormone-disrupting activity occurs in treated effluents • Proposal for HELCOM Recommendations

  4. Status of marine ecosystem Poor status of Baltic marine ecosystemHeavily disturbed by hazardous substances

  5. Major sources and pathways of HBCDD

  6. How to choose effective measures for emission reduction of hazardous substances? • different types of measures • measures for a single substance or cross-substances

  7. Cost effectiveness of different measures: case of PFOS • Substitution should tackle the biggest sources • Cost-effectiveness of End-of-Pipe depends on target substance spectrum Substitution at industrial sources End of pipe at urban sources Photographic industries EoP measure at Municipal waste water treatment plants (activated carbon) Semi-conductor industries Cross substance effect (+PFOA) Metal Plating CSE (+PFOA, NP) Cost effectiveness of different measures for PFOS

  8. Future main deliveries • Screening of discharges, summary • by summer 2011 • Sources, emission and inputs to the Sea • an advanced compilation by summer 2011 • Measures • in draft guidance documents for each substance, April 2011, • final guidances and draft recommendations by Sept. 2011 • Final conference • 11-12 October 2011, Helsinki • Final reports by early 2012
