空气污染是当今城市环境最大的问题之一。就污染空气的成分而言，重金属尤为重要。这是因为重金属可以在自然界中长期存在而不被分解，并且在环境中的浓度不断增加。它们也倾向于生物积累。因此，确定重金属浓度对于确定高风险区域和风险水平至关重要。植物通常被用作测定空气中重金属浓度的生物监测仪。测定植物中的重金属浓度对于确定植物从空气中去除重金属的能力至关重要，因此可以作为提高空气质量和监测空气质量的手段。本研究的目的是确定不同交通密度地区某些景观植物中不同重金属浓度随交通密度的变化。为此，在交通密集、交通不密集和几乎没有交通的地区采集了景观研究中经常使用的柳、刺槐、苦参和马尾木叶样，并通过重金属分析测定了Pb、Cu、Ca、Mg、Cd、Cr、Ni、Fe、Mn和Zn的含量。结果表明，Cd、Ni和Zn的平均值最高。在古巴，铅和锰的平均值最高。海马和其他元素都是在inS上发现的。粳稻。在交通密度高的地区；其中Cd、Ni、Zn含量最高。其中Cu、Mg、Cr、Fe和Mn含量最高。粳稻。在交通密度高的地区，只发现了最高的Pb值。海马中Ca含量最高的是r。pseudoacacia。基于这些结果，可以得出结论：babylonicaandS。日本是很好的生物指示剂。
Air pollution is one of the biggest problems of urban environments today. Heavy metals are particularly important in terms of components that pollute the air. This is due to the reason that heavy metals can stay in nature for a long time without being disintegrated, and their concentration in the environment is constantly increasing. They also tend to bioaccumulate. Therefore, determination of the heavy metal concentration is crucial for identifying high-risk areas and the level of risk. Plants are generally used as biomonitors for determining heavy metal concentration in the air. Determination of heavy metal concentrations in plants is crucial in determining the ability of plants to remove heavy metals from the air, and thus being used as a means of increasing air quality, as well as monitoring air quality. The aim of this study was to determine the variation of different heavy metal concentrations depending on traffic density in certain landscape plants collected from areas where traffic density is at different levels. For this purpose, leaf samples ofSalix babylonica, Robinia pseudoacacia, Sophora japonica,andAesculus hippocastanum, which are frequently used in landscaping studies, were collected from individuals where there was dense traffic, less dense traffic, and almost no traffic, and the quantities of Pb, Cu, Ca, Mg, Cd, Cr, Ni, Fe, Mn, and Zn were determined by heavy metal analysis. Based on the results, the highest mean values of Cd, Ni, and Zn were found inS. babylonica, highest mean values of Pb and Mn were found inA. hippocastanum, and those of other elements were found inS. japonica. In areas with a high traffic density; the highest values of Cd, Ni and Zn were found inS. babylonicaand the highest values of Cu, Mg, Cr, Fe and Mn were found inS. japonica. In areas with high traffic density, only the highest value of Pb was found inA. hippocastanumand the highest value of Ca was found inR. pseudoacacia. Based on these results, it can be concluded thatS. babylonicaandS. japonicaare good bioindicators.
