标准摘要
[中文适用范围]: 本国际标准为评估受污染土壤和土壤材料表征的生物利用度的方法的选择和应用提供了指导。 本国际标准没有给出最佳适用方法的选择,但规定了所用方法的边界条件和原则,并给出了方法开发的最低要求。 从此类方法获得的结果可用作风险评估方法中生物利用度的估计。 在本国际标准中,当仅为了简化而引用术语“土壤”时,应考虑更广泛的术语“土壤和土壤材料”。 本国际标准中考虑的污染物是金属(包括准金属)和有机污染物(包括有机金属化合物)。 本国际标准也适用于源自自然地质和土壤过程的金属(自然土壤地球化学含量)。 本国际标准也适用于沉积物。 注:基于土壤或土壤材料中污染物总量的生物可利用部分的评估程序有助于制定基于风险的土壤评估程序的监管要求。 根据设想的保护目标,推荐了现有方法的应用并讨论了其局限性,旨在促进可用于土壤和场地评估的可行标准方法的开发和引入。 需要这些方法来量化影响生物利用度的因素。 [外文原描述]: ISO 17402:2008 provides guidance for the selection and application of methods to assess bioavailability for the characterisation of contaminated soil and soil materials. ISO 17402:2008 does not give a selection of the best applicable methods, but specifies boundary conditions and principles of methods to be used and gives the minimal requirements for the development of methods. The results obtained from such methods can be used as an estimate of bioavailability in a risk-assessment approach. The contaminants considered in ISO 17402:2008 are metals, including metalloids, and organic contaminants, including organometal compounds. This International Standard is also applicable to metals originating from natural geological and pedological processes (natural pedo-geochemical content). ISO 17402:2008 can also be applied to sediments.
