1 SOLUTIONS for present and future emerging pollutants in land and water resources management W. Brack and more than 100 scientists from 39 institutions

2 39 partners 12 mio Euro Start: Duration: 5 years funded by the European Commission (Grant Nr ) Page 2

3 Where are we today? No good ecological status in most European river basins (WFD) Chemicals play a significant role for degradation Priority pollutants often don t explain effects emerging pollutants? Page 3

4 Where are we today? Chemosphere 80 mio known chemicals 14 mio commercially available ca in daily use > compounds in environmental samples Abundance 1e TIC: WER046.D 45 priority pollutants (chemical status) Emerging pollutants (e.g. pharmaceuticals, personal care products, biocides, transformation products) in daily use widespread not regulated, not systematically monitored often polar, ionic, multifunctional ( difficult ) often poorly retained in WWTPs occur in mixtures may exhibit great biological activity Time--> Page 4

5 Where do we want to go? Objectives of SOLUTIONS: Conceptual framework for prioritisation, assessment and abatement of pollutants (eco and human health) Efficient tools for identification of substances and mixtures posing a risk (e.g. River Basin Specific Pollutants, RBSPs): effect-based and analytical tools for early detection and identification integrated models and databases for risk modelling exploiting data from chemical authorisation (e.g. REACH) and monitoring Demonstration in trans-european case studies (Danube, Rhine, Iberian Peninsula) Page 5

6 Where do we want to go? Products: Solutions for prioritisation, assessment and management of emerging pollutants: user-friendly guidelines, computer tools and recommendations abatement options in waste and drinking water management common knowledge base on a wide range of toxicants scenarios and solutions for upcoming risks potential opportunities and obstacles for cooperation of WFD with other policies Page 6

7 Conceptual Framework Many chemicals in the environment but only few determine the risk. Example: mixture toxicity of 15 anti-androgenic compounds in typical environmental concentrations (data from 2005): (Kortenkamp & Faust, 2010) 5 chemicals explain 80% of the risk. Prioritisation and management needs to focus on these chemicals Page 7

8 Conceptual Framework However: Rapidly changing Fungicides viclozoline and procymidone are now forbidden and replaced by other fungicides of unknown antiandrogenic activity. Example: iprodione Required: Concept for aggregate assessment and prioritisation of legacy, present and up-coming pollutants Page 8

9 Conceptual Framework legacy chemicals presently used future chemicals effect-based and chemical monitoring and EDA exposure and risk modelling demonstration and mutual validation in case studies scenarios chemicals knowledge base, abatement options Page 9

10 Criteria for sustainable use Society Predict, prioritize and minimize future risks Chemicals Scenarios and models to predict risks Monitoring Identify and prioritise hazardous chemicals at different scales Modelling Abatement options Selection of abatement options Environment Legal and Policy Instruments Decision support for chemicals and water management Cost-benefit analysis Evaluation of abatament options Criteria for efficient abatement Abatement Options Analysis of policy instruments RBSPs and European Scale Priority Pollutants Sustainable use of Chemicals Solutions-oriented approach: Prioritisation considering abatement options
