摘要：本文描述了一种污染风险优先级方法的发展近况，这种方法用来对比评估不同土地利用和活动区的暴雨污水排放情况。指南用“发生可能性”和“影响严重性”来评估现有数据。通过在总悬浮物、生化需氧量、铅和镉上的应用证实了这种方法的实用性。提议基准方案代表了一种透明、可审计机制，支持多种来源的数据合成并且能够灵活合并使用化学、物理和/或者经济数据集合。实践者在两个关键方面参与开发和实现污染物减排项目。首先通过接收水域扩散污染源和/或污染物基础，一定流域尺度上进行风险比较评估和优先排序。其次，该方法报告合适的污染扩散控制策略选择。

Abstract:This paper describes the development of a pollutant risk prioritisation methodology for the comparative assessment of stormwater pollutants discharged from differing land use types and activities.Guidelines are presented which evaluate available data with respect to ‘likelihood of occurrence’ and ‘severity of impact’.The use of the developed approach is demonstrated through its application to total suspended solids, biochemical oxygen demand, lead and cadmium.The proposed benchmarking scheme represents a transparent and auditable mechanism to support the synthesis of data from a variety of sources and is sufficiently flexible to incorporate the use of chemical, physical and/or ecological data sets.Practitioners involved in developing and implementing pollutant mitigation programmes are assisted in two key ways.Firstly through enabling the risks to receiving waters from diffuse pollutionon a source-by-source and/or pollutant-by-pollutant basisat a catchment scaleto be comparatively assessed and prioritised. Secondly, the methodology informs the selection of appropriate diffuse pollution control strategies.
