This study evaluated the applications of ecotoxicity for management plan on industrial waste, and suggested the strategy for assessment of the ecotoxicological characteristic. From the results of ecotoxicity for waste synthetic resin, sludge, slag, waste dust, etc. 20 industrial wastes, 15 waste samples were analyzed in ecotoxic. In particular, 8 waste samples (about 62%) among the 13 non-hazardous wastes were confirmed ecotoxic. Therefore, the additional studies are necessary by increasing the number of samples and confirming the various types of waste. The correlation coefficient of arsenic and vanadium was highly estimated that 0.68, 0.44, respectively. The ecotoxicity for wastes should be managed as a comprehensive toxic in the future. Because the wastes has the high potential ecotoxic by the possibility of containing hazardous materials with discharge process and the interaction of heavy metals, ions, salt, and pH and so on. The hazardous characteristic of waste for ecotoxicity should be evaluated through the ecotoxic analysis in 3 steps by the proposed procedure for assessment of ecotoxicological characteristic.
