Heavy metals concentrations of (Cr, Zn, Fe, Cu and Ni) were determined in plants and soils contaminated with electroplating industrial effluent. The ranges of total soil Cr, Zn, Fe, Cu and Ni concentrations were found to be 1443-3240, 1376-3112, 683-2228, 263-374 and 234-335 mg kg⁻¹, respectively. Metal accumulation, along with hyperaccumulative characteristics of the screened plants was investigated. Present study highlighted that metal accumulation in different plants varied with species, tissues and metals. Only one plant (Amaranthus viridis) accumulated Fe concentrations over 1000 mg kg⁻¹. On the basis of TF, eight plant species for Zn and Fe, three plant species for Cu and two plant species for Ni, could be used in phytoextraction technology. Although BAF of all plant species was lesser than one, these species exhibited high metal adaptability and could be considered as potential hyperaccumulators. Phytoremediation potential of these plants can be used to remediate metal contaminated soils, though further investigation is still needed.
重金属（Cr、Zn、Fe、Cu 和 Ni）的浓度在受电镀工业废水污染的植物和土壤中进行了测定。土壤中总 Cr、Zn、Fe、Cu 和 Ni 的浓度范围分别为 1443-3240、1376-3112、683-2228、263-374 和 234-335mg/kg。研究了筛选植物的重金属积累及其超积累特性。本研究表明，不同植物对金属的积累随物种、组织和金属的不同而变化。只有一种植物（苋菜）积累的 Fe 浓度超过 1000mg/kg。基于转移因子（TF），有 8 种植物可用于 Zn 和 Fe 的植物提取技术，有 3 种植物可用于 Cu，有 2 种植物可用于 Ni。尽管所有植物的 BAF 均小于 1，但这些植物表现出较高的金属适应性，可被视为潜在的超积累植物。这些植物的植物修复潜力可用于修复受金属污染的土壤，但仍需要进一步研究。
