灌溉工程使用处理过的废水指南. 第4部分: 监测

[中文适用范围]： 本文件提供了以下方面的建议： ——监测用于灌溉的处理废水（TWW）的质量； ——监测灌溉植物； ——监测土壤的盐度； ——监测邻近环境中的天然水源； ——监测水库水质。 它强调抽样方法及其频率。 关于分析方法，本文件引用了标准方法，或者在没有可用的情况下引用了其他参考文献。 注：如果已经存在监测计划，则可以将这些建议整合到该计划中。 当实施更广泛的风险管理方法时尤其如此，例如世界卫生组织制定的水安全计划（作为卫生安全计划的典范）[16]。 [外文原描述]： This document provides recommendations regarding: — monitoring the quality of treated wastewater (TWW) for irrigation; — monitoring irrigated plants; — monitoring the soil with regard to salinity; — monitoring natural water sources in neighbouring environments; — monitoring the quality of water in storage reservoirs. It puts emphasis on sampling methods and their frequency. Regarding the methods of analysis, this document refers to standard methods or, where not available, to other bibliographical references. NOTE In cases where a monitoring plan already exists, these recommendations can be integrated into this plan. This is notably the case when a broader approach of risk management is implemented, such as the water safety plans (serving as a model for sanitation safety plans) developed by WHO [16] .
