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
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
Status of marine ecosystem Poor status of Baltic marine ecosystemHeavily disturbed by hazardous substances
How to choose effective measures for emission reduction of hazardous substances? • different types of measures • measures for a single substance or cross-substances
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
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• by summer 2011 • Sources, emission and inputs to the Sea • an advanced compilation by summer 2011 • Measures • in draft guidance documents for each substance, April 2011, • final guidances and draft recommendations by Sept. 2011 • Final conference • 11-12 October 2011, Helsinki • Final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
