Abstract. Heavy-metal contamination of Pinus pinaster, P. sylvestris, Quercus robur, and Q. rotundifolium was studied in four abandoned historic Cu deposits from Italy (Libiola, Caporciano), Portugal (Sao Domingos), and Slovakia (L'ubietova). The highest Cu and Mn contents in anthropogenic soil were described in Libiola and Caporciano whereas the highest Pb, Zn, As, and Sb contents in Sao Domingos. The anthropogenic soil in L'ubietova shows the highest Co contents. The area of Sao Domingos is the most acidified. There are important differences between the bioaccumulation of plants from individual deposits. Bioavailability of the heavy metals is generally independent of the pH values. The high Ca and Mg contents in soil are able to block the transport of heavy metals to the plant tissues. The bioconcentration factor values of all plant taxa, in all deposits, indicate a predominant strategy of excluders. Only Ag shows excellent bioconcentration ability. In L'ubietova, Pinus sylvestris has a strategy as an accumulator of Pb (2.43) and Zn (2.49); Pinus pinaster of Mn (4.97), Cd (1.85), and Co (5.62) and Quercus rotundifolium of Mn (3.54) in Sao Domingos. The predominantly low translocation factor values indicate that in most cases the heavy metals are accumulated in roots; only in a few rare cases do they migrate to shoots (e.g. Zn in Pinus sp. from all localities, Co in P. pinaster in Sao Domingos).

<i>Pinus</i> sp. 重金属生物富集特性的比较。和 <i>Quercus</i> sp。在选定的欧洲铜矿床中

摘要。在来自意大利(Libiola、Caporciano)、葡萄牙(Sao Domingos)和斯洛伐克(L'ubietova)的四个废弃的历史铜矿床中研究了 Pinus pinaster、P. sylvestris、Quercus robur 和 Q. rotundifolium 的重金属污染。在 Libiola 和 Caporciano 中描述了人为土壤中最高的 Cu 和 Mn 含量,而在 Sao Domingos 中描述了最高的 Pb、Zn、As 和 Sb 含量。L'ubietova 的人为土壤中 Co 含量最高。圣多明各斯地区酸化程度最高。来自单个沉积物的植物的生物积累之间存在重要差异。重金属的生物利用度通常与 pH 值无关。土壤中高钙和镁含量能够阻止重金属向植物组织的运输。所有植物分类群的生物浓度因子值,在所有存款中,表明排除者占主导地位。只有 Ag 显示出优异的生物浓缩能力。在 L'ubietova 中,Pinus sylvestris 具有作为 Pb (2.43) 和 Zn (2.49) 的蓄积者的策略;圣多明各斯的 Mn (4.97)、Cd (1.85) 和 Co (5.62) Pinus pinaster 和 Mn (3.54) 圆叶栎。主要的低易位因子值表明,在大多数情况下,重金属在根部积累;只有在极少数情况下,它们才会迁移到枝条上(例如,所有地区的松属中的锌,圣多明各斯松树中的 Co)。62) 和 Quercus rotundifolium of Mn (3.54) in Sao Domingos。主要的低易位因子值表明,在大多数情况下,重金属在根部积累;只有在极少数情况下,它们才会迁移到枝条上(例如,所有地区的松属中的锌,圣多明各斯松树中的 Co)。62) 和 Quercus rotundifolium of Mn (3.54) in Sao Domingos。主要的低易位因子值表明,在大多数情况下,重金属在根部积累;只有在极少数情况下,它们才会迁移到枝条(例如,所有地方的松属中的锌,圣多明各斯松树中的钴)。
