The tests simulating the acid rain environment and natural rain water were conducted to gain insight regarding the behavior of the elements during weathering and to determine their toxicity characteristics. In the tests using TCLP method, the solubility levels of Fe, Zn and Mn detected in the leachate of the whole brick pieces were in agreement with the drinking water standards. In the tests using ASTM method, no detectable level of any element was found in the leachates of the whole brick pieces and of ground brick. In the tests using TCLP method, the solubility concentrations of the elements such as Fe, Zn, Cu, Cr, Ni, and Mn from the leachate of the ground brick were higher than those of the whole brick pieces. However, only Fe, Ni and Mn concentrations were determined to be higher than those allowed in the drinking water standards.EnglishAcid rainFly ashManganeseManganese removal (water treatment)NickelPotable waterRainSolubilityTestingToxicityZincDrinking water standardsFly ash brickGain insightMn concentrationsPotentially toxic elementsSolubility levelToxic elementsToxicity characteristicsBrickConference paper
