Coal conversion solid wastes were sieved and leached according to procedures of the ASTM, EPA and a nitric acid extraction procedure designed by the authors. Leachates from all size fractions were analysed for organics, heavy metals and acute toxicity to Daphnia magna. The ASTM-A procedure leached the least material, and the HNO/SUB/3 extraction the most. The quantity of metal leached increased with decreasing particle size. None of the solid waste samples would be considered hazardous according to the Resource Conservation and Recovery Act; however, slag leachates from one type of sample contained Fe at more than 100 times the secondary drinking water standard. EPA leachates and ASTM-A sludge leachates were strongly toxic to Daphnia magna. A linkage was developed between normalised metal concentration, Daphnia magna toxicity and EPA drinking water standards.
