the highest share of purification and pyrolytic treatment of coal (49%, hazardous waste 66.8 kt) 07 : Wastes from organic chemical processes (40%, 414 kt) Percentage of waste Approximately 20% considered as hazardous by H14 Ecotoxicity tests are applied Prioritization of tests (aquatic Only aquatic tests on leaching extracts vs terrestrial) Leaching/extraction test used UNE 12457-2 Aquatic tests Protocol used No calculation methods are used Illustrative examples - Advantages Spain highlights that there are often problems due to the fact that wastes are complex matrices (coloured, oily, particulates, precipitates, etc.). Qualitative Considering that often the ecotoxicity test is the assessment of the only real bioassay performed on waste, as it is by method(s) far the cheapest, it seems reasonable to use a test battery. The applied toxicity tests (Daphnia magna, Vibrio fischeri) are relatively economic and simple. The Daphnia test is in general
