Dust, as a source of trace metal elements, affects the health of society. The spatial and temporal concentrations of dust‐bound trace metals (Cd, Pb, Ni, Zn, Cu, and Mn) in Kuhdasht watershed (456 km²), Lorestan Province, Iran, is investigated. Dust is collected using glass traps placed in ten research stations in the region. The spatial and temporal distribution of dust trace metals are plotted using ARC‐GIS. The highest and the lowest concentrations of Zn (9751150 mg kg⁻¹), Pb (46.352.9 mg kg⁻¹), and Cd (2.443.30 mg kg⁻¹) are obtained in winter, of Ni (98110 mg kg⁻¹) and Cu in autumn (16.053.5 mg kg⁻¹), and of Mn in summer (385505 mg kg⁻¹). The spatial concentrations of dust‐bound trace metals indicate all, except Cu, show a decreasing trend from the mountains toward the plains, similar to that of soil and of dust, except for Zn, which shows higher concentrations in dust than in soil. The potential sources of dust‐bound trace metals and their rate of contamination are also investigated using the enrichment and contamination factors. The major sources of Cd and Zn in the dust of watershed are due to anthropogenic activities or from activities outside the borders.

伊朗Kuhdasht流域周围粉尘微量金属元素的时空分布

灰尘作为微量金属元素的来源，会影响社会的健康。研究了伊朗洛雷斯坦省Kuhdasht流域（456 km ²）中尘埃结合的痕量金属（Cd，Pb，Ni，Zn，Cu和Mn）的时空浓度。使用放置在该地区十个研究站的玻璃阱收集灰尘。尘埃痕量金属的时空分布是使用ARC‐GIS绘制的。Zn中的最高和最低浓度（9751150毫克千克^-1），铅（46.352.9毫克千克^-1），和Cd（2.443.30毫克千克^-1）在冬季得到的Ni（98110毫克公斤，^{- 1}）和秋季的Cu（16.053.5 mg kg ^-1），夏季的Mn（385505 mg kg ^-1）。尘埃结合的痕量金属的空间浓度表明，除铜外，所有其他成分均从山地向平原呈现下降趋势，与土壤和粉尘相似，但锌除外，而锌比粉土中的浓度更高。还使用富集和污染因子研究了粉尘结合的痕量金属的潜在来源及其污染率。流域粉尘中Cd和Zn的主要来源是由于人为活动或边界外活动造成的。
