Environmental contamination with Cadmium (Cd) is of great concern due to its hazardous effects on living organisms.Query In the present research, Leucaena leucocephala plants were exposed to Cd concentrations of 5, 10, and 15 mg/L to determine their potential use in Cd remediation. Different parameters including Cd uptake, macro/micronutrient content, chlorophyl, and catalase production were determined. Results indicated that Cd uptake by L. leucocephala roots did not show a significant difference between treatments. However, a significant increase in Cd content (Tukey´s HSD) was observed in stems as Cd levels in the media augmented. The highest Cd content (830 ± 20 mg/kg) was determined in stems of plants exposed to 15 mg/L Cd, and no Cd was detected in leaves. Data showed that as Cd concentration increased in the media, Ca, Mg, K, Zn, and Mn decreased. Moreover, while the presence of Cd reduced catalase activity in roots, chlorophyll production was not affected.

镉 (Cd) 对环境的污染因其对生物体的危害而备受关注。在本研究中，银合欢植物暴露于 5、10 和 15 mg/L 的 Cd 浓度下，以确定其潜在用途光盘修复。测定了不同的参数，包括 Cd 吸收、大量/微量营养素含量、叶绿素和过氧化氢酶产量。结果表明L. leucocephala对 Cd 的吸收根在处理之间没有显示出显着差异。然而，随着培养基中 Cd 水平的增加，在茎中观察到 Cd 含量（Tukey's HSD）显着增加。在暴露于 15 mg/L Cd 的植物茎中测定出最高的 Cd 含量 (830 ± 20 mg/kg)，而在叶子中未检测到 Cd。数据显示，随着培养基中 Cd 浓度的增加，Ca、Mg、K、Zn 和 Mn 减少。此外，虽然 Cd 的存在降低了根中的过氧化氢酶活性，但叶绿素的产生并未受到影响。
