Contaminations of soil and water resources with various organic and inorganic compounds are of great importance on account of the close relationship between the living organisms and their feeding. That is due to direct impact in supplying food for living organisms in terms of environmental and human health aspects. In this regard, the present study aimed to investigate the phytoremediation potential of H. strobilaceum and S. herbacea in contaminated soils. For this purpose, soil and plant samples were collected from around the sewage channel in Eshtehard industrial region of Iran. Sampling started at the edge of the channel and ended in a distance of 500 m from the channel. The distance of 1000 m from channel was considered as the control point. ICP-OES was used for the measurement of heavy metals. The obtained results showed that the highest and lowest amounts of soil lead (Pb) were 17.6 and 2.33 mg kg−1, respectively. For Cadmium (Cd), the values ranged from 0.341 to 0.11 mg kg −1 at 21–50 cm depth for the control point. For the plants, the highest and lowest amount of Pb belonged to H. strobilaceum shoot (10.38 mg kg −1) and S. herbacea root (7.54 mg kg −1), respectively. The maximum (1.64 mg kg−1) and minimum (0.36 mg kg−1) Cd concentration was observed in the root and shoot of H. strobilaceum, respectively. In both species, Translocation Factor (TF) for Pb and Cd was greater than 1 and less than 1, respectively. Cd Bio Concentration Factor (BCF) in the roots of both species was estimated to be greater than 1 while for Pb, this index was smaller. Bio Accumulation Factor (BAF) in the shoots of Pb and Cd for both plants were lower and greater than 1, respectively. In general, the results revealed that the highest concentrations of Cd and Pb are absorbed and stored by the underground organs of H. strobilaceum and S. herbacea and these plants have the ability to remove Pb and Cd from contaminated soils.

某工业城镇周边的金针草和草本植物的植物修复能力

由于生物与它们的摄食之间的密切关系,各种有机和无机化合物对土壤和水资源的污染非常重要。这是由于在环境和人类健康方面直接影响为生物体提供食物。在这方面,本研究旨在调查H. strobilaceumS. herbacea的植物修复潜力在受污染的土壤中。为此,我们从伊朗 Eshtehard 工业区的污水通道周围收集了土壤和植物样本。采样从通道边缘开始,在距离通道 500 m 处结束。以距河道 1000 m 的距离为控制点。ICP-OES 用于重金属的测量。结果表明,土壤铅(Pb)的最高和最低含量分别为17.6和2.33 mg kg -1。对于镉 (Cd),控制点在 21-50 厘米深度处的值范围为 0.341 至 0.11 mg kg -1 。对植物而言,最高和最低的铅含量分别属于H. strobilaceum shoot (10.38 mg kg -1 ) 和S. herbacea根(7.54 mg kg -1)。最大(1.64 mg kg -1)和最小(0.36 mg kg -1 )Cd 浓度分别在H. strobilaceum的根和茎中观察到。在这两个物种中,Pb 和 Cd 的易位因子 (TF) 分别大于 1 和小于 1。估计这两个物种根中的 Cd 生物浓度因子 (BCF) 大于 1,而对于 Pb,该指数较小。两种植物的 Pb 和 Cd 芽中的生物累积因子 (BAF) 分别低于和大于 1。总的来说,结果表明,最高浓度的 Cd 和 Pb 被H. strobilaceumS. herbacea的地下器官吸收和储存。这些植物有能力从受污染的土壤中去除铅和镉。
