Monitoring of pollution in the vicinity of roads connected to winter road maintenance is one of the important tools for optimising winter maintenance technology and reducing its environmental impact. The aim of this study was to determine the relationship between winter road maintenance and the increased concentration of sodium ion to characterise the harm caused by the de-icing agents on selected types of individual components grown in the Norway spruce ecosystem. The model area is located in the immediate vicinity of the D1 motorway connecting Prague and Brno (Czech Republic), at 103 km. The area is thus exposed to long-term contamination from automobile transport, and the monitoring was carried out for 3 consecutive years. A clear effect of the de-icing agents on conifers near the road has been demonstrated by the symptoms of salt damage visually observed in close proximity to the road (at a sampling distance of 5 m). The needles of these spruce trees also showed increased sodium concentrations, regardless of the age of the needles. The study also confirms that sodium accumulates in all selected components of the analysed ecosystem (moos, humus, soil). The sodium concentration has been found to decrease with increasing distance from the road for all of the components.

监测与冬季道路养护相关的道路附近的污染是优化冬季养护技术和减少其环境影响的重要工具之一。本研究的目的是确定冬季道路维护与钠离子浓度增加之间的关系，以表征除冰剂对挪威云杉生态系统中生长的特定类型的个别成分造成的危害。模型区位于连接布拉格和布尔诺（捷克共和国）的 D1 高速公路附近，全长 103 公里。因此，该地区长期受到汽车运输的污染，连续3年进行监测。除冰剂对道路附近针叶树的明显影响已通过在道路附近（在 5 m 采样距离处）目视观察到的盐害症状得到证明。这些云杉树的针叶也显示出钠浓度增加，无论针叶的年龄如何。该研究还证实，钠在所分析生态系统的所有选定成分（moos、腐殖质、土壤）中积累。已发现钠浓度随着与道路距离的增加而降低，对于所有组件。腐殖质，土壤）。已发现钠浓度随着与道路距离的增加而降低，对于所有组件。腐殖质，土壤）。已发现钠浓度随着与道路距离的增加而降低，对于所有组件。
