ABSTRACT

The goal of this paper was to analyze changes in the spatial pattern of metals in water and determining the factors that may be associated with that distribution using the asymmetric eigenvector maps and redundancy analyses in the Matanza Riachuelo river (MRR), Argentina. Data from 2008 and 2014 of metal concentrations (As, Cd, Cu, Cr, Ni, and Pb), water quality parameters and land cover variables from 38 samplings sites in the MRR were collected. The results obtained showed that the general spatial pattern of distribution of all the metals analyzed did not differ between both years and that the water flow was a factor that structured the distribution of metals in the river. The present study showed the utility of using these multivariate analyses to assess the dynamics of the spatial distribution of a group of metals in an urban basin.

使用多元分析评估地表水中金属污染的空间格局变化:案例研究来自阿根廷布宜诺斯艾利斯的一个城市盆地

摘要

本文的目的是分析水中金属的空间格局变化,并使用非对称特征向量图和阿根廷Matanza Riachuelo河(MRR)的冗余度分析来确定可能与该分布有关的因素。收集了MRR中38个采样点的金属浓度(As,Cd,Cu,Cr,Ni和Pb),水质参数和土地覆盖变量的2008年和2014年数据。所获得的结果表明,所分析的所有金属的总体空间格局在两年之间没有差异,并且水流量是构成河流中金属分布的一个因素。本研究表明,使用这些多元分析来评估城市盆地中一组金属的空间分布动态是有用的。
