Abstract

Motor transport affects the state of the natural environment and results in the accumulation of trace metals in roadside soils. The trace metal concentrations in roadside soils depend mainly on the distance from the road and the traffic intensity. The aim of the investigations was to determine the range of the environmental impact of the (Cracow-Zakopane) transport route and the effect of traffic intensity on the concentrations of trace metals in the soil. Three road sections differing in their traffic intensity were selected for this purpose. The concentrations of Cr, Cu, Ni, Pb and Zn in soil samples taken from a depth of 0-30 cm at a distance of 5, 10, 50 and 100 metres from the road were spectrophotometrically determined. The metal concentrations in the surroundings of the Cracow-Myślenice road carrying heavy traffic were found to be several times higher than the ones in the soils near the Łopuszna-Dursztyn local road with low traffic intensity. The largest differences in trace metal concentrations in the soils were found for nickel (four times higher concentrations along the Cracow-Myślenice road) at all the considered distances and for copper (three times higher) at the distances of 5 and 10 metres. In comparison with the reference areas, in the vicinity of the investigated roads the concentrations of Cr, Cu, Ni, Pb and Zn in the soil were found to be elevated. The fact that the concentrations of the trace metals decrease with increasing distance from the road's edge clearly indicates the traffic-related origin of the contaminants.

不同交通强度道路附近土壤中微量金属浓度的测定

汽车运输影响自然环境状态，导致路边土壤中微量金属的积累。路边土壤中微量金属的含量主要与道路距离和交通强度有关。调查的目的是确定(克拉科夫-扎科帕内)运输路线对环境的影响范围以及交通强度对土壤中微量金属浓度的影响。为此选择了三个交通强度不同的路段。用分光光度法测定了距离公路5、10、50、100米深度0 ~ 30 cm土壤样品中Cr、Cu、Ni、Pb、Zn的浓度。研究发现，交通流量较大的Cracow-Myślenice公路周边土壤中金属的浓度比交通强度较小的Łopuszna-Dursztyn公路附近土壤中金属的浓度高数倍。在所有考虑的距离上，土壤中微量金属浓度的差异最大的是镍(沿Cracow-Myślenice公路的浓度高4倍)，而在5米和10米的距离上，铜(高3倍)。与对照区相比，调查道路附近土壤中Cr、Cu、Ni、Pb和Zn的浓度均有所升高。痕量金属的浓度随着离道路边缘距离的增加而降低，这一事实清楚地表明污染物的来源与交通有关。

期刊介绍： The quarterly journal Roads and Bridges – Drogi i Mosty is published by the Road and Bridge Research Institute since September 2012 as a bilingual English-Polish journal. From 2002 to 2012 the journal was printed under the title Drogi i Mosty. The journal mission is to promote current achievements in science and technology in the field of road and bridge engineering. The journal is intended as a forum of the exchange of innovative concepts and solutions between the researches from different countries. Original scientific and technical papers in the field of civil engineering and related engineering sciences are published. The scope of Roads and Bridges – Drogi i Mosty includes design, construction, maintenance and safe use of roads, bridges, airports and other transportation structures.
