本文概述了教科文组织国际水文计划支持的一系列拟议的综合科学倡议讲习班的第一个讲习班。讲习班汇集了水文学家、环境化学家、微生物学家、稳定同位素专家和自然资源管理人员，目的是就评估流域尺度上的微生物降解过程和反应性迁移的方法交流新的想法。重点是流域尺度上的扩散污染和化合物特异性同位素分析（CSIA）在农用化学品生物降解过程评估中的应用。主要成果是确定水停留时间分布与污染物降解率之间的联系，确定需要更好地了解化合物特定微生物降解同位素分异因素，以及CSIA在确定关键降解过程中的潜力。在自然资源管理方面，制定了一个框架，其中确定了CSIA技术实际上具有独特的能力，可以作为与扩散污染评估问题有关的一系列尺度（微观到扩散）的过程的分布式综合指标。版权所有©2006约翰威利父子有限公司
A summary is provided of the first of a series of proposed Integrated Science Initiative workshops supported by the UNESCO International Hydrological Programme. The workshop brought together hydrologists, environmental chemists, microbiologists, stable isotope specialists and natural resource managers with the purpose of communicating new ideas on ways to assess microbial degradation processes and reactive transport at catchment scales. The focus was on diffuse contamination at catchment scales and the application of compound‐specific isotope analysis (CSIA) in the assessment of biological degradation processes of agrochemicals. Major outcomes were identifying the linkage between water residence time distribution and rates of contaminant degradation, identifying the need for better information on compound specific microbial degradation isotope fractionation factors and the potential of CSIA in identifying key degradative processes. In the natural resource management context, a framework was developed where CSIA techniques were identified as practically unique in their capacity to serve as distributed integrating indicators of process across a range of scales (micro to diffuse) of relevance to the problem of diffuse pollution assessment.
