The Bolesław-Bukowno mining area in Poland is highly polluted by elements such as Zn, Pb, Cd and As. The reactivity and mobility of toxic elements such as Tl are poorly known. Here, we studied by sequential extraction the mobility of As, Cd, Co, Cr, Cu, Mn, Mo, Pb, Tl and Zn in sediments from two water reservoirs near Bukowno. Results show that available As, Co, Mn, Pb and Zn are found in carbonate minerals. Available Cd, Cu and Tl are found in sulphides and organic matter. The extractability of As, Cr, Mo and Tl was rather poor. By contrast, 85 % of total Cd, Pb and Zn was mobile. We discuss Tl and Mo association in carbonate sediments from ore deposits.

波兰矿区碳酸盐沉积物中有毒元素的迁移率。

波兰博莱斯瓦夫-布科诺矿区受到锌、铅、镉、砷等元素的严重污染。人们对铊等有毒元素的反应性和迁移性知之甚少。在这里，我们通过顺序提取研究了布科诺附近两个水库沉积物中砷、镉、钴、铬、铜、锰、钼、铅、铊和锌的迁移率。结果表明，碳酸盐矿物中含有有效的As、Co、Mn、Pb和Zn。有效的镉、铜和铊存在于硫化物和有机物中。As、Cr、Mo、Tl 的萃取率较差。相比之下，总 Cd、Pb 和 Zn 的 85% 是可移动的。我们讨论了矿床碳酸盐沉积物中 Tl 和 Mo 的伴生。
