Abstract :

Leachate samples from fly ash and bottom ash obtained by gasification of solid wastes were analyzed by non-targeted screening using liquid chromatography-quadrupole-time of flight-mass spectrometry (LC-QTOF-MS). The results were used to determine which organic compounds could contribute to the toxicity of the leachates of solid waste gasification. Subsequently, the effects of the leachate on mortility and immobility of Daphnia mangna were evaluated as a method for monitoring water quality, and as a screening method for toxicity assessment of solid waste re-utilization.
