Bryophyte species composition and 26 common physico-chemical and inorganic chemical parameters were assessed at 23 selected sites in the Maritsa River (BG) over a 4-year period. Principal components analyses (PCA) of both bryophytes and water variables distinguished different locations in the ecosystem. The data imply that the content of elements measured in bryophytes represents river contamination, while species compositional patterns reflect hydromorphology and general degradation. This study for the first time combined aquatic bryophyte occurrence, the bioaccumulation of 17 macro-and microelements in 17 species, and 26 water factors by principal components analysis (PCA) in an assessment of river pollution.
在 4 年的时间里，在马里察河（BG）的 23 个选定地点评估了苔藓植物的物种组成和 26 个常见的物理化学和无机化学参数。苔藓植物和水质变量的主成分分析（PCA）区分了生态系统中的不同位置。数据表明，苔藓植物中测量元素的含量代表了河流污染，而物种组成模式则反映了水力学形态和一般退化。本研究首次将水生苔藓植物的出现、17 种大型和微量元素的生物积累以及 26 种水因子通过主成分分析（PCA）结合起来，评估了河流污染。
