Scope
This standard specifies the terms and definitions, test substance information, test principle, reference substances, overview of test methods, test procedure, quality assurance and quality control, data and report for the aerobic and anaerobic transformation test of chemicals in soil. This standard is used to evaluate the aerobic and anaerobic transformation of chemical substances in soil; it is used to determine the transformation rate of chemical substances under the action of plants and soil microorganisms, as well as the nature, formation rate, and degradation rate of transformation products. This standard is applicable to all chemicals (including radiolabeled or non-labeled substances) that are low volatility, water-soluble or water-insoluble, and can be accurately measured. This standard is not applicable to chemical substances that are highly volatile in soil and cannot be retained in soil under the test conditions.
本标准规定了化学品土壤中好氧厌氧转化试验的术语和定义、受试物信息、试验原理、参比物质、试验方法概述、试验程序、质量保证与质量控制、数据与报告。本标准用于评价化学物质在土壤中的好氧和厌氧转化；用于测定化学物质在植物和土壤微生物作用下的转化率，以及转化产物的性质和生成率、降解率。本标准适用于低挥发性的、水溶性或非水溶性、能够被精确测定的所有化学品(包括放射性标记物或非标记物)。本标准不适用于在土壤中具有易挥发性，且本试验条件下无法在土壤中保留的化学物质。

This standard specifies the method for testing aerobic and anaerobic transformation of chemicals in soil, including terms and definitions, test substance information, test principle, reference substances, test procedure, quality control, and data reporting. It is applicable to low-volatility, water-soluble or water-insoluble chemicals, and is used to evaluate transformation rates, the nature of transformation products, and their formation and degradation rates. The test is conducted under constant temperature and dark conditions using static or dynamic flow systems, analyzing parent substances and transformation products, and calculating parameters such as half-life through mass balance. The standard is not applicable to volatile substances and provides detailed requirements for soil selection, handling, storage, and test conditions.
