本国际标准规定了测定土壤和土壤中苯氧基链烷酸的方法 质量浓度为50纳克/升的饮用水（详细信息见附件A表A.1）。实例 表1中给出了可以通过该方法测定的苯氧基链烷酸。 该方法可适用于表1中未提及的化合物或其它类型的水。然而，它是 有必要验证该方法对这些特殊情况的适用性（见附录B）。 表1-通过该方法测定的植物处理剂

This International Standard specifies a method for the determination of phenoxyalkanoic acids in ground and drinking water in mass concentrations W 50 ng/l (detailed information is given in Table A.1 of annex A). Examples of phenoxyalkanoic acids which can be determined by this method are given in Table 1. This method may be applicable to compounds not mentioned in Table 1 or to other types of water. However, it is necessary to verify the applicability of this method for these special cases (see annex B). Table 1 — Plant treatment agents determined by this method
