本研究通过对口蹄疫动物尸体处置场渗滤液（FMD渗滤液）的化学分析和生态毒性试验，为开发口蹄疫渗滤液环境风险评价工具提供基础数据。在化学分析方面，评估了，，，韩国标准方法检测从动物尸体掩埋场释放到地下水的渗滤液的指标和NRN（茚三酮-活性氮），一个新建议的筛选测试指标，以检测口蹄疫渗滤液对地下水的污染。对于生态毒性试验，发光细菌（V. fischeri）、微藻（P. subcapitata）和水蚤（D.大）被选为测试物种。通过相关性分析，确定了监测FMD渗滤液污染的较好指标。通过回归分析，确定了口蹄疫渗滤液污染样品中各指标对费氏弧菌半数最大毒性效应的浓度。本研究结果可应用于口蹄疫渗滤液的风险评估，并建立口蹄疫渗滤液风险管理的指导方针。
In this study, chemical analysis and ecotoxicity tests of leachate from disposal site for foot-and-mouth disease carcasses (FMD leachate) were conducted to collect fundamental data that will be used to develop environmental risk assessment tools for FMD leachate. For chemical analysis, concentration of , , Korea standard method indicators for detection of leachate released from animal carcasses burial site into groundwater and NRN (Ninhydrin-Reactive Nitrogens), a newly suggested screening test indicator to detect groundwater contamination by FMD leachate, were assessed. For ecotoxicity tests, luminescent bacteria (V. fischeri), micro-algae (P. subcapitata) and water flea (D. magna) were selected as test species. Correlation analysis between the concentration of , , NRN and the toxicity to V. fischeri was performed to identify the better indicators to monitor FMD leachate contamination. From regression analysis, the concentration of the indicators in FMD leachate contaminated sample that induced halfmaximal toxic effect to V. fischeri was evaluated. Results obtained from this study can be applied to assess the risk by FMD leachate and to establish the guideline to manage risk in relation to FMD leachate.
