这项工作的主要目的是集中在布尔达河（波兰）的水质分类和1994-2002年期间监测测量获得的污染数据的评价。本研究介绍了选定的化学计量学技术对污染监测数据集的应用，即聚类分析、主成分分析、判别分析和因子分析。获得的结果可以确定具有相似污染特征的自然集群和监测地点组，并确定重要的判别变量。化学计量学分析证实了环境保护局对布尔达河水质纯度的分类，但结果显示监测地点之间的差异更大。这样可以更好地评价监测区域的水质。根据化学计量学方法，还发现在观察的时间段内，一些地点受到城市污染的高度影响，另一些地点受到农业（农田排放）的影响。(c) 2005 Elsevier Ltd版权所有。
The main aim of this work is focused on water quality classification of the Brda river (Poland) and evaluation of pollution data obtained by the monitoring measurement during the period 1994-2002. The study presents the application of selected chemometric techniques to the pollution monitoring dataset, namely, cluster analysis, principal component analysis, discriminant analysis and factor analysis. The obtained results allowed to determine natural clusters and groups of monitoring locations with similar pollution character and identify important discriminant variables. Chemometric analysis confirmed the classification of water purity of the Brda river made by the Inspection of Environmental Protection but the results showed more differentiation between monitored locations. This enables better evaluation of the water quality in a monitored region. On the basis of the chemometric approach, it was also found that some locations were under the high influence of municipal contamination, and some others under the influence of agriculture (discharges from fields) within the observed time period.
