Urban dust is a mixture of deposited particles from different sources usually linked to potentially toxic elements (PTEs). Despite the industrialization of many South American countries, little is known about the impact of particulate matter in large cities, data necessary to promote environmental policies aiming to protect human health. The main objective of this work was to evaluate the particle size distribution, composition, as well as environmental and human health risks of settled dust particles from Barranquilla, a Colombian Caribbean industrialized area. Trace elements were analyzed by ICP-MS from thirty-five different sites, covering all city areas. Dust was mostly composed of 10-70 μm particles. The average concentrations of V, Cr, Mn, Co, Ni, Cu, Zn, As, Se, Mo, Ag, Cd, Sn, Sb, Pb, and Bi were above background. High spatial heterogeneity was observed for Cu, Zn, As, Se, Mo, Ag, Sn, Sb, and Bi. Concentration factors suggest urban dusts are extremely contaminated by Zn and Cu. The ecological risk associated with specific elements decreased in the order Cd > Cu > As > Hg > Pb > Ni > Co ≈ Zn ≈ Cr, and the contamination load index showed that 91% of the samples are polluted by PTEs. Although the carcinogenic risks of Cr, Ni, As, Co, and Cd were low, chronic exposure to several PTEs may be impacting the quality of life. Educational programs, as well as monitoring and greater control on traffic, industry, and construction activities, are needed in order to protect environmental and human health.

与接触哥伦比亚加勒比巴兰基亚城市灰尘中存在的危险元素相关的环境和人类健康风险

城市灰尘是来自不同来源的沉积颗粒的混合物,通常与潜在有毒元素 (PTE) 相关。尽管许多南美国家实现了工业化,但对大城市中颗粒物的影响知之甚少,这些数据是促进旨在保护人类健康的环境政策所必需的。这项工作的主要目的是评估来自哥伦比亚加勒比工业化地区巴兰基亚的沉降粉尘颗粒的粒径分布、组成以及环境和人类健康风险。通过 ICP-MS 分析了 35 个不同地点的痕量元素,覆盖了所有城市地区。灰尘主要由 10-70 μm 的颗粒组成。V、Cr、Mn、Co、Ni、Cu、Zn、As、Se、Mo、Ag、Cd、Sn、Sb、Pb 和 Bi 的平均浓度高于背景。观察到 Cu、Zn、As、Se、Mo、Ag、Sn、Sb 和 Bi 的高空间异质性。浓度因子表明城市灰尘受到锌和铜的严重污染。与特定元素相关的生态风险依次为 Cd > Cu > As > Hg > Pb > Ni > Co ≈ Zn ≈ Cr,污染负荷指数显示 91% 的样品被 PTEs 污染。尽管 Cr、Ni、As、Co 和 Cd 的致癌风险较低,但长期接触多种 PTE 可能会影响生活质量。为了保护环境和人类健康,需要开展教育计划以及对交通、工业和建筑活动进行监测和加强控制。本文受版权保护。版权所有。浓度因子表明城市灰尘受到锌和铜的严重污染。与特定元素相关的生态风险依次为 Cd > Cu > As > Hg > Pb > Ni > Co ≈ Zn ≈ Cr,污染负荷指数显示 91% 的样品被 PTEs 污染。尽管 Cr、Ni、As、Co 和 Cd 的致癌风险较低,但长期接触多种 PTE 可能会影响生活质量。为了保护环境和人类健康,需要开展教育计划以及对交通、工业和建筑活动进行监测和加强控制。本文受版权保护。版权所有。浓度因子表明城市灰尘受到锌和铜的严重污染。与特定元素相关的生态风险依次为 Cd > Cu > As > Hg > Pb > Ni > Co ≈ Zn ≈ Cr,污染负荷指数显示 91% 的样品被 PTEs 污染。尽管 Cr、Ni、As、Co 和 Cd 的致癌风险较低,但长期接触多种 PTE 可能会影响生活质量。为了保护环境和人类健康,需要开展教育计划以及对交通、工业和建筑活动进行监测和加强控制。本文受版权保护。版权所有。Ni > Co ≈ Zn ≈ Cr,污染负荷指数显示 91% 的样品被 PTEs 污染。尽管 Cr、Ni、As、Co 和 Cd 的致癌风险较低,但长期接触多种 PTE 可能会影响生活质量。为了保护环境和人类健康,需要开展教育计划以及对交通、工业和建筑活动进行监测和加强控制。本文受版权保护。版权所有。Ni > Co ≈ Zn ≈ Cr,污染负荷指数显示 91% 的样品被 PTEs 污染。尽管 Cr、Ni、As、Co 和 Cd 的致癌风险较低,但长期接触多种 PTE 可能会影响生活质量。为了保护环境和人类健康,需要开展教育计划以及对交通、工业和建筑活动进行监测和加强控制。本文受版权保护。版权所有。需要以保护环境和人类健康。本文受版权保护。版权所有。需要以保护环境和人类健康。本文受版权保护。版权所有。
