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.
摘要:
在这项研究中,镉(Cd)的浓度,铁(Fe),锰(Mn),镍(Ni),从山采样的植物中的铅(Pb)和锌(Zn)。Madra被调查。此外,应用正矩阵分解(PMF)模型研究了潜在有毒金属的分布特征和来源识别。26种不同植物的样品取自Mt。使用多点采样方法在海拔177至1347m之间的Madra。通过ICP-OES测量的金属含量为以下顺序(平均值±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)。根据确定最高值的植物样品,金属如下:Cd(Lathyruslaxiflorus,0.401mg/kg),Fe(侧凸,7621.207mg/kg),Mn(栗子,724.927mg/kg),Ni(夏枯草,6.947mg/kg),铅(斯蒂维尼山,3.955毫克/千克)和锌(夏枯草,50.802mg/kg)。PMF模型的结果表明,Cd具有源自工业活性的大气迁移因子,Ni具有衬底因子,Fe,Mn,铅和锌受不同人为因素的影响。
