Canadian goldenrod (Solidago canadensis L.) is a plant that grows in a variety of environmental conditions. It shows high capability to spread in various habitats, including fallow lands and brownfield land. The research aimed at analyzing the content of Pb and Zn in the underground (roots, rhizomes) and aboveground parts (stems, leaves, inflorences) of Solidago canadensis (SC) originating from two locations that are clearly different in terms of metal content in soil. Statistically significant differences were determined in the content of Pb and Zn in soil and particular morphological parts of the plant, depending on the sampling location. It has been shown that in the conditions of increased (compared with natural) Pb and Zn content in the soil, SC may serve as a bioaccumulator of these metals. It was determined that SC can be used as a phytostabilizer of Pb and Zn in soils heavily contaminated with these elements. The content of Zn in the aboveground parts of SC indicates that this plant can also be used for phytoextraction of soils contaminated with this metal.
加拿大一枝黄花（Solidago canadensis L.）是一种生长在多种环境条件下的植物。它具有在各种栖息地（休耕地和棕地）中扩散的高能力。该研究旨在分析来自两个土壤金属含量明显不同的地点的 Solidago canadensis（SC）的地下（根、根茎）和地上部分（茎、叶、花序）中 Pb 和 Zn 的含量。根据采样地点的不同，土壤和植物特定形态部分中 Pb 和 Zn 的含量存在显著差异。结果表明，在土壤中 Pb 和 Zn 含量增加（与自然相比）的情况下，SC 可能是这些金属的生物蓄积体。研究还表明，SC 可以用作严重污染土壤中 Pb 和 Zn 的植物稳定剂。SC 地上部分的 Zn 含量表明，该植物还可以用于提取受这种金属污染的土壤。
