The Amu Darya River, one of the most important water resources for Uzbekistan and Turkmenistan, was declared a World Disaster Zone in 1991. The great increase in irrigation and the use of pesticides has led to both a lack of water and drinking water contamination. The aim of the present study, part of an EU project on water management guidelines, was to evaluate the leachability of 71 organic pesticides commonly employed in the area, and to assess compounds that could potentially contaminate the river and impair drinking water quality. A multivariate approach is proposed for the pesticide screening, condensing information from different environmental partition indexes (GUS, "modified LEACH", LIN) into a single ranking, the Global Leachability Index (GLI). For a selected data set in water medium this super-index identifies three classes with a risk potential for pesticide leachability, and allows the selection of a small number of chemicals for an analytical survey.
阿姆河是乌兹别克斯坦和土库曼斯坦最重要的水资源之一，1991年被宣布为世界灾区。灌溉用水的大幅增加和农药的使用导致了水资源短缺和饮用水污染。本研究是欧盟水管理指南项目的一部分，旨在评估该地区常用的71种有机农药的淋溶性，并评估可能污染河流和损害饮用水质量的化合物。本文提出了一种多变量方法用于农药筛选，将来自不同环境分配指数（GUS、“改良LEACH”、LIN）的信息浓缩为一个单一排名，即全球淋溶性指数（GLI）。对于水介质中的选定数据集，这个超级指数识别出具有农药淋溶风险潜力的三类物质，并允许选择少量化学品进行分析调查。
