Abstract
Anthropic activities related to urbanization release pollutants, including potentially toxic elements which can deposit in soils, water, and vegetation. Thus, soil and plant leaves are widely used as ecological indicators to assess the effect of urbanization. This study aimed to evaluate the impact of urbanization based on the elemental concentration of soil and leaves of Tilia × europaea from urban, suburban, and rural areas along an urbanization gradient in Debrecen, Hungary. The rural area was situated near Nagyerdő, a protected area for nature conservation The suburban area was intermediate between the rural and urban areas regarding urban density. The urban study area was at the centre of the urban community to maximize the observable effect of urban pollution. Using inductively coupled plasma optical emission spectrometry (ICP-OES) technique, the concentration of Ba, Cd, Co, Cr, Cu, Ni, Pb, Sr, and Zn was analysed and based on them, bioaccumulation factor (BAF) was calculated. The highest concentration of all elements was found in soil samples from urban areas, with an increasing tendency along the urbanization gradient. A significant difference was found along the urbanization gradient only for Cr based on the plant leaves. T. × europaea showed bioaccumulation capacity for Cr and Sr. Our results suggest that urbanization has a remarkable effect on the elemental concentration of soil, which is a perfect ecological indicator. At the same time, we concluded that the T. × europaea was not sufficiently sensitive to detect the effect of urbanization.
与城市化有关的人为活动释放污染物，包括可能沉积在土壤、水和植被中的潜在有毒元素。因此，土壤和植物叶片被广泛用作评价城市化效应的生态指标。以匈牙利德布勒森城市、近郊和农村为研究区，研究了城市化对土壤和叶类元素浓度的影响。农村地区位于纳耶尔德附近，这是一个自然保护区，郊区在城市密度方面介于农村和城市之间。城市研究区位于城市社区的中心，以最大限度地观察城市污染的影响。采用电感耦合等离子体发射光谱法（ICP-OES）分析了样品中Ba、Cd、Co、Cr、Cu、Ni、Pb、Sr和Zn的浓度，并计算了生物积累因子（BAF）。各元素在城市土壤样品中的浓度最高，且随城市化梯度呈增加趋势。仅基于植物叶片的Cr在城市化梯度上存在显著差异。结果表明，城市化对土壤元素浓度有显著影响，土壤元素浓度是一个较好的生态指标。与此同时，我们得出结论，T. x europaea对城市化影响的敏感度不够。
期刊介绍：
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
