Abstract The paper presents the first data on the concentrations of heavy metals (Cd, Pb, Zn, Cu, Ni, Cr, Mn) and 137Cs and their contamination ratios (CR) in the most abundant species of macrophytes in the Vistula Lagoon. No significant differences in the concentrations of heavy metals and 137Cs between macrophyte taxa or the influence of rivers flowing into the Vistula Lagoon on heavy metal concentrations in the area were found. The concentrations of heavy metals in macrophyte taxa varied in the following ranges: Cd – 0.1–0.7 mg kg−1 d.w.; Pb – 0.5–5.0 mg kg-1 d.w.; Zn – 29–390 mg kg-1 d.w.; Cu – 2.5–8.3 mg kg-1 d.w.; Ni – 0.4–6.8 mg kg−1 d.w.; Cr – 0.5–2.8 mg kg−1 d.w.; Mn – 380–8500 mg kg−1 d.w. Since the 1990s, a decline or stable state of heavy metal concentrations in bottom sediments has been observed, reflecting changes in the environment of the Vistula Lagoon. The linear sedimentation rate in the Vistula Lagoon was 3.3 mm y−1. The results presented in the paper can serve as a baseline for assessing changes in the environmental status of the Vistula Lagoon, which may occur as a result of future investments, including building a new navigable canal through the Vistula Spit.

大型植物中的重金属和 137Cs 水平以及沉积物中的时间分布——河口环境状况评估的应用(维斯瓦泻湖——波罗的海南部)

摘要 本文首次提供了维斯杜拉泻湖中最丰富的大型植物物种中重金属(Cd、Pb、Zn、Cu、Ni、Cr、Mn)和 137Cs 的浓度及其污染率 (CR) 的数据。大型植物类群之间的重金属和 137Cs 浓度或流入维斯瓦泻湖的河流对该地区重金属浓度的影响均未发现显着差异。大型植物类群中重金属的浓度在以下范围内变化:Cd – 0.1–0.7 mg kg-1 dw;铅 – 0.5–5.0 mg kg-1 dw;锌 – 29–390 mg kg-1 dw;铜 – 2.5–8.3 mg kg-1 dw;Ni – 0.4–6.8 mg kg−1 dw;Cr – 0.5–2.8 mg kg−1 dw;Mn – 380–8500 mg kg−1 dw 自 1990 年代以来,已观察到底部沉积物中重金属浓度下降或处于稳定状态,反映了维斯瓦泻湖环境的变化。Vistula Lagoon 中的线性沉降率为 3.3 mm y-1。论文中提出的结果可以作为评估维斯瓦泻湖环境状况变化的基准,这可能是未来投资的结果,包括通过维斯瓦河口建造一条新的通航运河。
