Abstract

Peat was studied in order to assess the concentrations of heavy metals in it depending on the depth of occurrence. Genetically homogeneous peat layers with occurrence depths of 0–5, 5–35, 35–85, 85–140, 140–220, and 220–375 cm were analyzed for the concentrations of Ag, Hg, Pb, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Tl, and As. The metal concentrations were determined on an ICP-MS Aurora Elite inductively coupled plasma mass spectrometer (Bruker, Germany) using an internal standard containing the elements Bi, In, Li, Sc, Tb, and Y. The determination conditions were selected using a certified soil standard. The highest concentrations of the test metals were observed in the upper layer of peat, and the concentration of metals decreased with depth of peat occurrence. A regularity was observed only for the elements Mn, Tl, Co, Ni, and Pb, and the other metals were uniformly distributed in peat layers and exhibited no regularity.

根据发生深度评估重金属对泥炭的污染

摘要

对泥炭进行了研究，以便根据发生的深度评估其中的重金属浓度。分析了发生深度为0-5、5-35、35-85、85-140、140-220和220-375 cm的遗传均质泥炭层中Ag，Hg，Pb，Cr，Mn，Fe的浓度，Co，Ni，Cu，Zn，Cd，Tl和As。使用包含Bi，In，Li，Sc，Tb和Y元素的内标，在ICP-MS Aurora Elite电感耦合等离子体质谱仪（德国布鲁克）上测定金属浓度。土壤标准。在泥炭的上层中观察到最高浓度的测试金属，并且随着泥炭深度的增加，金属的浓度降低。仅对元素Mn，Tl，Co，Ni和Pb观察到规律性，
