Abstract

In this study, the concentrations of cadmium (Cd), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn) in plants sampled from Mt. Madra were investigated. Furthermore, the distribution characteristics and source identification of potentially toxic metals were investigated with the application of Positive Matrix Factorization (PMF) modelling. Samples of 26 different plant species were taken from Mt. Madra at elevations ranging from 177 to 1347 m using the multi-point sampling approach. The metal quantities measured by ICP-OES are the following sequences (mean ± SD) (mg/kg): Fe (974.96 ± 29.6) > Mn (111.81 ± 2.6) > Zn (27.28 ± 0.2) > Ni (2.17 ± 0.03) > Pb (0.77 ± 0.01) > Cd (0.12 ± 0.01). According to the plant samples in which the highest values were determined, the metals are as follows: Cd (Lathyrus laxiflorus, 0.401 mg/kg), Fe (Ajuga orientalis, 7621.207 mg/kg), Mn (Castanea sativa, 724.927 mg/kg), Ni (Prunella laciniata, 6.947 mg/kg), Pb (Crataegus stevenii, 3.955 mg/kg) and Zn (Prunella laciniata, 50.802 mg/kg). The results of the PMF model showed that Cd had an atmospheric transport factor originated and transported from industrial activites, Ni had a substrate factor, Fe, Mn, Pb and Zn were influenced by different anthropogenic factors.

通过正矩阵因式分解鉴定马德拉山高山生态系统植物中潜在有毒金属的来源。

本研究调查了从马德拉山采样的植物中镉 (Cd)、铁 (Fe)、锰 (Mn)、镍 (Ni)、铅 (Pb) 和锌 (Zn) 的浓度。此外，还应用正矩阵因式分解（PMF）模型研究了潜在有毒金属的分布特征和来源识别。采用多点取样法从海拔 177 米至 1347 米的马德拉山采集了 26 种不同植物的样本。通过 ICP-OES 测得的金属量如下（平均值 ± SD）（毫克/千克）：铁（974.96 ± 29.6）>锰（111.81 ± 2.6）>锌（27.28 ± 0.2）>镍（2.17 ± 0.03）>铅（0.77 ± 0.01）>镉（0.12 ± 0.01）。根据测定出最高值的植物样本，这些金属如下：镉（Lathyrus laxiflorus，0.401 mg/kg）、铁（Ajuga orientalis，7621.207 mg/kg）、锰（Castanea sativa，724.927 mg/kg）、镍（Prunella laciniata，6.947 mg/kg）、铅（Crataegus stevenii，3.955 mg/kg）和锌（Prunella laciniata，50.802 mg/kg）。PMF 模型的结果表明，镉的大气迁移因子来自工业活动，镍的基质因子，铁、锰、铅和锌受不同人为因素的影响。
