Ecotoxicological Evaluation of Industrial Waste Materials and Anorganic Composites Containing Waste Materials

Abstract

This work sums up results of tests of ecotoxicity that were made on different kind of industrial waste materials like classical ash, fluid and fly ash, slags as well as anorganic composites containing waste materials. Composites might be used for building materials in the future. Ecotoxicological tests were used for evaluation of ecotoxicity, represented by 4 trophic levels, with several bioindicators evaluated at different exposure time periods. The battery of classical tests includes a growth inhibition test of the freshwater alga Raphidocellis subcapitata, an immobilization test of the cladoceran Daphnia magna and freshwater fish Poecilia reticulata and a test of inhibitive effects on the root growth of white mustards Sinapis alba. Tests with enchytraeidae, collembolan and lettuce were chosen from group of contact tests. It was realized confrontation between classical test with seeds of mustard and contact tests with seeds of lettuce. Results of ecotoxicity tests were determination of percentage of mortality, immobilization, stimulation or inhibition of growth for testing organisms. It was made comparison of results individual ecotixicity tests. Results of classical aquatic tests were compared with contact tests realized in artificial ground
