Identification of wastes hazardous to the environment in mirror entries of the AVV

The ecotoxicological characterisation of waste according to the European Waste List is part of the assessment as hazardous or non-hazardous. So far, no methodological details have been fixed concerning the hazard criterion H14 (‘ecotoxic’). Using the recommendations of the CEN Guideline 14735 (2005), experiences made in an international ring test sponsored by UBA, and a proposal for the ecotoxicological characterisation of wastes, 24 representative waste samples with different properties were identified, sampled according to standard procedures, and – with one exception (galvanic sludge) – ecotoxicologically tested. Selection criteria for testing of these waste samples were the mirror entry, the quantitative and economic relevance, coverage of the European Waste List, the opinion of different German federal states, waste properties, specifics of recycling or disposal as well as problems with their classification. No chemical investigation of the waste samples was performed. The samples were characterised according to their properties in the ABANDA data base. Based on the project results, recommendations for sampling and sample preparation are provided. For ecotoxicological characterisation, three eluate tests (algae test, Daphnia test, umu genotoxicity test) and three solid waste tests (plant test with Brassica napus, earthworm avoidance test, bacteria contact test) were performed. All investigations were performed as limit tests. According to a literature review, suitable limit concentrations were identified: LID4 for eluates and LID8 for solid wastes. Algae, plants and bacteria were the most sensitive test organisms. None of the waste eluates showed any indication of genotoxicity. Further studies are required to evaluate the sensitivity of the umu genotoxicity test. It is proposed to perform a plausibility check of the H14-classification.
