What is Leaching and Toxicity Behavior of Coal–biomass Waste Cocombustion Ashes about?

## Abstract Land disposal of ash residues, obtained from the cocombustion of Greek lignite with biomass wastes, is known to create problems due to the harmful constituents present. In this regard, the leachability of trace elements from lignite, biomass, and blends cocombustion ashes was investigated by using the Toxicity Characteristic Leaching Procedure (TCLP) of the US Environmental Protection Agency (US EPA). In this work, the toxicity of the aqueous leachates and the concentrations of the metals obtained from the leaching procedure were measured using the Microtox test (__Vibrio fischeri__) and inductive coupled plasma‐atomic emission spectrometer (ICP‐AES), respectively. The toxic effects of most leachates on __Vibrio fischeri__ were found to be significantly low in both 45% and 82% screening test protocols. However, the liquid sample originating from olive kernels fly ash (FA4) caused the highest toxic effect in both protocols, which can be attributed to its relatively high concentrations of As, Cd, Co, Cu, Mn, Ni, and Zn. © 2006 Wiley Periodicals, Inc.
