The aim of the study was to estimate the ability of ten tree and bush species to tolerate and accumulate Cd, Cu, Pb, Zn, and As species [As(III), As(V), and total organic arsenic] in industrial sewage sludge extremely contaminated with arsenic (almost 27.5 g kg(-1)) in a pot experiment. The premise being that it will then be possible to select the most promising tree/bush species, able to grow in the vicinity of dams where sewage sludge/flotation tailings are used as landfill. Six of the ten tested tree species were able to grow on the sludge. The highest content of total As was observed in Betula pendula roots (30.0 ± 1.3 mg kg(-1) DW), where the dominant As species was the toxic As(V). The highest biomass of Quercus Q1 robur (77.3 § 2.6 g) and Acer platanoides (76.0 § 4.9 g) was observed. A proper planting of selected tree species that are able to thrive on sewage sludge/flotation tailings could be an interesting and promising way to protect dams. By utilizing differences in their root systems and water needs, we will be able to reduce the risk of fatal environmental disasters.
本研究的目的是通过盆栽试验，评估10种乔木和灌木物种耐受和积累镉、铜、铅、锌以及砷物种[砷（III）、砷（V）和总有机砷]的能力，试验所用工业污水污泥被砷严重污染（砷含量近27.5 g·kg⁻¹）。前提是届时将有可能选出最有前景的乔木/灌木物种，它们能够在使用污水污泥/浮选尾矿作为填埋物的大坝附近生长。10种受试乔木物种中有6种能够在污泥上生长。白桦根中总砷含量最高（30.0±1.3 mg·kg⁻¹干重），其中主要的砷物种是有毒的砷（V）。观察到欧洲栓皮栎（77.3±2.6 g）和挪威槭（76.0±4.9 g）的生物量最高。合理种植能够在污水污泥/浮选尾矿上茁壮成长的选定乔木物种，可能是保护大坝的一种有趣且有前景的方法。通过利用它们根系和水分需求的差异，我们将能够降低致命环境灾难的风险。
