We review the evolution, state of the art and future lines of research on the sources, transport pathways, and sinks of particulate trace elements in urban terrestrial environments to include the atmosphere, soils, and street and indoor dusts. Such studies reveal reductions in the emissions of some elements of historical concern such as Pb, with interest consequently focusing on other toxic trace elements such as As, Cd, Hg, Zn, and Cu. While establishment of levels of these elements is important in assessing the potential impacts of human society on the urban environment, it is also necessary to apply this knowledge in conjunction with information on the toxicity of those trace elements and the degree of exposure of human receptors to an assessment of whether such contamination represents a real risk to the city's inhabitants and therefore how this risk can be addressed.
我们回顾了城市陆地环境中颗粒态微量元素的来源、迁移途径和汇的演变、现状和未来研究方向，包括大气、土壤、街道和室内灰尘。这些研究揭示了一些历史上受到关注的元素（如 Pb）排放量的减少，因此人们的兴趣集中在其他有毒微量元素上，如 As、Cd、Hg、Zn 和 Cu。虽然确定这些元素的水平对于评估人类社会对城市环境的潜在影响很重要，但也有必要将这些知识与有关这些微量元素的毒性以及人类受体暴露程度的信息结合起来，以评估这种污染是否对城市居民构成真正的风险，以及如何应对这种风险。
