Heavy metal pollution is an important concern because of its potential to affect human health. This study was conducted to analyze plants growing on a landfill body and in its surroundings to determine their potential for heavy metal accumulation. In addition, the enrichment coefficient (EC) for the plant/soil system was used for determining the environmental contamination from a landfill in terms of heavy metal accumulation. The samples were taken in 2013-2014. Of the analyzed metals, iron achieved the highest values in the samples, i.e. - stalk (103.4-6564.6 mg/kg DM), roots (6563.6-33,036.6 mg/kg DM), leaf (535.1-11,275 mg/kg DM) and soil (12,389-39,381.9 mg/kg DM). The highest concentrations were determined in 2013 for Fe, Mn and Zn. Iron achieved the highest concentrations in the years 2013-2014. Next, EC values were then calculated, with the highest noted for Cd. Cd, as well as Cr, Ni and Zn are accumulated mostly in the leaves, whereas Co, Cu, Fe, Hg, Mn and Pb are accumulated mainly in the roots of T. vulgare.
重金属污染是一个重要的关注点，因为它有可能影响人类健康。本研究旨在分析生长在垃圾填埋体及其周围的植物，以确定它们对重金属积累的潜在能力。此外，还使用植物/土壤系统的富集系数（EC）来确定垃圾填埋场重金属积累造成的环境污染。这些样本是在 2013 年至 2014 年期间采集的。在所分析的金属中，铁在样本中的含量最高，即-茎（103.4-6564.6mg/kg DM）、根（6563.6-33036.6mg/kg DM）、叶（535.1-11275mg/kg DM）和土壤（12389-39381.9mg/kg DM）。Fe、Mn 和 Zn 的最高浓度是在 2013 年确定的。铁在 2013-2014 年的浓度最高。然后计算了 EC 值，Cd 的值最高。Cd 以及 Cr、Ni 和 Zn 主要积累在叶片中，而 Co、Cu、Fe、Hg、Mn 和 Pb 主要积累在 T. vulgare 的根部。
