Evaluation of the impact of transport on the surrounding environment requires an ecosystem approach: to analyze components that provide information about the distribution of concentrations of the monitored contaminants and to allow an estimate of the dynamics of movement of these substances in the environment. Trees are used for biomonitoring for wide range of contaminants, coming not only from air pollution from industry or transport but also from winter chemical road maintenance. The research paper presents the determination of sodium and chloride ions content in assimilative organs of conifers and evaluates the influence of the contamination potential on these ions contents in needles of the Scots pine (Pinus sylvestris) and Norway spruce (Picea abies). Scots pine is studied a useful bioindicator for different tip of trace elements, but in the case of influence of winter maintenance, there is not so deep focusing as in the case of spruce. We have used this species of conifers for their usual occurrence. To assess the differences between sensitivity of salinity of different type of needles, the results of analysis of first- and second-year needles of Scots pine needles and samples of the Norway spruce were compared. The study was conducted in two different areas (for Scots pine and Norway spruce) in the Czech Republic. Samples of soils were collected near each tree of interest. The results of ions concentrations (Na, Cl) were evaluated depending on two factors: the distance from the road and the age of the needles. For evaluation of the impact of transport on the surrounding environment also the concentrations of wide range of elements were measured. The study confirmed a higher sensitivity of Norway spruce to salinity than in Scots pine. Given the confirmed increased sensitivity of spruce stands to the effects of winter road maintenance, spruce is not an appropriate tree species for the immediate vicinity of road infrastructure. Increased NaCl accumulation in the assimilation organs of the conifer trees near the road was confirmed and scales with concentrations were established to assess the degree of contamination.

评估运输对周围环境的影响需要一种生态系统方法：分析可提供有关所监测污染物浓度分布信息的成分，并能够估算这些物质在环境中的运动动态。树木用于生物监测各种污染物，不仅来自工业或运输业造成的空气污染，还来自冬季化学道路维护。该研究论文介绍了针叶树同化器官中钠和氯离子含量的测定方法，并评估了污染潜力对苏格兰松（Pinus sylvestris）和挪威云杉（Picea abies）的针中这些离子含量的影响。）。苏格兰松树被研究为一种适用于痕量元素不同尖端的生物指示剂，但在冬季维护的影响下，没有像云杉这样的深度聚焦。我们将这种针叶树种用于它们的平常发生。为了评估不同类型针的盐度敏感性之间的差异，比较了苏格兰松针的第一年和第二年针以及挪威云杉样品的分析结果。这项研究在捷克共和国的两个不同地区（苏格兰松和挪威云杉）进行。在每棵感兴趣的树附近收集土壤样品。根据两个因素评估离子浓度（Na，Cl）的结果：距道路的距离和针头的年龄。为了评估运输对周围环境的影响，还测量了各种元素的浓度。该研究证实，挪威云杉对盐度的敏感性高于苏格兰松树。鉴于已确认的云杉林对冬季道路养护的敏感性提高，因此云杉不是紧邻道路基础设施的合适树种。证实了道路附近针叶树同化器官中NaCl积累的增加，并建立了浓度标度以评估污染程度。鉴于已确认的云杉林对冬季道路养护的敏感性提高，因此云杉不是紧邻道路基础设施的合适树种。证实了道路附近针叶树同化器官中NaCl积累的增加，并建立了浓度标度以评估污染程度。鉴于已确认的云杉林对冬季道路养护的敏感性提高，因此云杉不是紧邻道路基础设施的合适树种。证实了道路附近针叶树同化器官中NaCl积累的增加，并建立了浓度标度以评估污染程度。
