Evaluation of biological methods for a future methodological implementation of the Hazard criterion H14 'ecotoxic' in the European waste list (2000/532/EC).
The ecotoxicological characterization of waste is part of its assessment as hazardous or non-hazardous according to the European Waste List. For this classification 15 hazard criteria are derived from the Council Directive 91/689/EEC on hazardous waste. Some of the hazard criteria are based on the content of dangerous substances. The criterion H14 'ecotoxic' lacks of an assessment and testing strategy and no specific threshold values have been defined so far. Based on the recommendations of CEN guideline 14735 (2005), an international round robin test (ring test) was organized by the German Federal Environment Agency in order to define suitable test methods for the biological assessment of waste and waste eluates. A basic test battery, consisting of three aquatic and three terrestrial tests, was compiled. In addition, data were submitted for ten additional tests (five aquatic (including a genotoxicity test) and five terrestrial ones). The tests were performed with three representative waste types: an ash from an incineration plant, a soil containing high concentrations of organic contaminants (polycyclic aromatic hydrocarbons) and a preserved wood waste. The results of this ring test confirm that a combination of a battery of biological tests and chemical residual analysis is needed for an ecotoxicological characterization of wastes. With small modifications the basic test battery is considered to be well suitable for the hazard and risk assessment of wastes and waste eluates. All results and documents are accessible via a web-based data bank application.
