This study investigated levels and sources of pollution and potential health risks associated with potentially toxic elements (PTEs) and polycyclic aromatic hydrocarbons (PAHs) in urban street dust collected from Tyumen city, a large transport centre with one of the highest motorization rates in Russia. Twenty street dust samples were collected from four grades of roads in five different land use areas. Research methods included measurements of physical and chemical properties of street dust, concentrations of 18 PTEs using inductively coupled plasma mass spectrometry, 12 PAHs using high-performance liquid chromatography, and statistical analysis of the data. Concentrations of Ni, Cr, Sb, and Mo, as well as medium and high molecular weight PAHs in urban street dust, were notably higher than in soils within the city, which indicates that transport is the main source of these elements. Concentrations of Cu, Cd, Pb, Zn, Mn, and As in street dust of Tyumen were lower compared to many large cities, while Cr, Ni, and Co were higher. Concentrations of PAH were comparable to other large nonindustrial cities. Total contamination of street dust by both PTEs and PAHs showed more robust relationships with the number of roadway lanes rather than land use. The estimated carcinogenic risks were low in 70% of samples and medium in 30% of samples. Noncarcinogenic risks were attributed to exposure to Co, Ni, V, and As. The total noncarcinogenic risk for adults was found to be negligible, while the risk was found to be moderate for children.

俄罗斯秋明市城市街道灰尘中潜在有毒元素和多环芳烃的污染状况及人体健康风险评估

本研究调查了从秋明市收集的城市街道灰尘中潜在有毒元素 (PTE) 和多环芳烃 (PAH) 的污染水平和来源以及潜在健康风险,秋明市是俄罗斯机动化率最高的大型交通中心之一。从五个不同土地利用区域的四个等级道路收集了二十个街道灰尘样本。研究方法包括测量街道灰尘的物理和化学性质,使用电感耦合等离子体质谱法测量 18 种 PTEs 的浓度,使用高效液相色谱法测量 12 种 PAHs,并对数据进行统计分析。城市街道灰尘中镍、铬、锑、钼以及中高分子量多环芳烃的含量明显高于城市土壤中的含量,这表明运输是这些元素的主要来源。与许多大城市相比,秋明街道灰尘中的Cu、Cd、Pb、Zn、Mn和As含量较低,而Cr、Ni和Co含量较高。PAH 的浓度与其他大型非工业城市相当。PTEs 和 PAHs 对街道灰尘的总污染显示出与道路车道数量而非土地使用的更密切的关系。估计的致癌风险在 70% 的样本中为低,在 30% 的样本中为中等。非致癌风险归因于接触 Co、Ni、V 和 As。成人的总非致癌风险被认为可以忽略不计,而儿童的风险被认为是中等的。与许多大城市相比,秋明的街道尘埃中的 As 较低,而 Cr、Ni 和 Co 较高。PAH 的浓度与其他大型非工业城市相当。PTEs 和 PAHs 对街道灰尘的总污染显示出与道路车道数量而非土地使用的更密切的关系。估计的致癌风险在 70% 的样本中为低,在 30% 的样本中为中等。非致癌风险归因于接触 Co、Ni、V 和 As。成人的总非致癌风险被认为可以忽略不计,而儿童的风险被认为是中等的。与许多大城市相比,秋明的街道尘埃中的 As 较低,而 Cr、Ni 和 Co 较高。PAH 的浓度与其他大型非工业城市相当。PTEs 和 PAHs 对街道灰尘的总污染显示出与道路车道数量而非土地使用的更密切的关系。估计的致癌风险在 70% 的样本中为低,在 30% 的样本中为中等。非致癌风险归因于接触 Co、Ni、V 和 As。成人的总非致癌风险被认为可以忽略不计,而儿童的风险被认为是中等的。PTEs 和 PAHs 对街道灰尘的总污染显示出与道路车道数量而非土地使用的更密切的关系。估计的致癌风险在 70% 的样本中为低,在 30% 的样本中为中等。非致癌风险归因于接触 Co、Ni、V 和 As。成人的总非致癌风险被认为可以忽略不计,而儿童的风险被认为是中等的。PTEs 和 PAHs 对街道灰尘的总污染显示出与道路车道数量而非土地使用的更密切的关系。估计的致癌风险在 70% 的样本中为低,在 30% 的样本中为中等。非致癌风险归因于接触 Co、Ni、V 和 As。成人的总非致癌风险被认为可以忽略不计,而儿童的风险被认为是中等的。
