Ecotoxicity Assessment of Substrates from a Thermally Active Coal Tailing Dump Using Tests for <i>Daphnia magna</i>

Abstract

The aim of the study was to compare the ecotoxicity of waste materials formed from a mixture of construction materials with tailings obtained from the thermally active Ema coal tailing dump located in the city of Ostrava, Czech Republic. The ecotoxicity assessment was performed using acute lethality tests on the crustacean Daphnia magna. The test results are relevant for further possibilities of using technogenic substrates from tailings after mining activities and are an integral part of a comprehensive assessment of their biological effects on the environment.
