The role of water and bottom sediment pollution of a river subjected to a strong industrial anthropo-pressure in coastal plants was investigated. The work presented the influence of polluted environment on accumulation of metal(loid)s (including arsenic and its species) in Stuckenia pectinata L., Galium aparine L., and Urtica dioica L. The study provided important information on the contents of organic and inorganic arsenic species in selected plants and their response to heavy metal and arsenic contamination. The As(III), As(V), AB (arsenobetaine), MMA (monomethylarsonic acid), and DMA (dimethylarsinic acid) ions were successfully separated on the Hamilton PRP-X100 column with high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS) techniques. The Pollution Load Index and geo-accumulation Index (I) values clearly indicate significant pollution of the examined ecosystem with heavy metals. The chemometric analysis with the concepts of (Dis)similarity Analysis, Cluster Analysis, and Principal Component Analysis helped to visualize the variability of the As species concentrations and to analyse correlations between sampling point locations and analyte contents.
研究了一条受到强烈工业人为压力的河流的水和底泥污染对沿海植物的影响。本工作研究了受污染环境对节节菜（Stuckenia pectinata L.）、拉拉藤（Galium aparine L.）和荨麻（Urtica dioica L.）中金属（类）元素（包括砷及其形态）积累的影响。该研究提供了关于选定植物中有机和无机砷形态含量及其对重金属和砷污染响应的重要信息。采用高效液相色谱-电感耦合等离子体质谱（HPLC-ICP-MS）技术，成功地在 Hamilton PRP-X100 柱上分离出 As(III)、As(V)、AB（砷甜菜碱）、MMA（一甲基砷酸）和 DMA（二甲基砷酸）离子。污染负荷指数和地积累指数（I）值清楚地表明，所研究的生态系统受到重金属的严重污染。基于（不）相似性分析、聚类分析和主成分分析概念的化学计量分析有助于可视化砷形态浓度的可变性，并分析采样点位置与分析物含量之间的相关性。
