Industrial activities tend to deteriorate adjacent agricultural lands due to accumulation of potentially toxic elements in soils and crops. However, better understanding of their distinctive source partitions and transfer process remains insufficient in steel-making area. The paper focuses on the pollution levels, health risks, and provenance identification of Tl, As, Pb, Cu, Ni, Co, Sb, Cd, Zn, Be, Cr, Fe, Mn, Mo, Sn, and V in common vegetables from different farmlands near a steel-making plant. The results showed that the Tl, As, Pb, Cd, Cr, Cu and Mn were of high-level contamination in soils and generally above the maximum permissible level (MPL). Calculation using hazard quotients (HQ) exhibited that consumption of the studied vegetables may entail significant health risks to residents, especially for children, resulting from the elevated contents of Tl, As and associated toxic elements. Calculation by binary mixing model using Pb isotopic compositions suggested that steel-making activities contributed to 35–80% of the contamination of Pb and As in vegetables. It is necessary to adopt appropriate remediation measures to mitigate the farmland contamination and ensure the food safety of the agricultural products.

由于土壤和作物中潜在有毒元素的积累，工业活动往往会恶化邻近的农业用地。然而，在炼钢领域，对其独特的源分区和转移过程的更好理解仍然不足。本文重点研究了常见蔬菜中 Tl、As、Pb、Cu、Ni、Co、Sb、Cd、Zn、Be、Cr、Fe、Mn、Mo、Sn 和 V 的污染水平、健康风险和来源鉴定来自炼钢厂附近的不同农田。结果表明，Tl、As、Pb、Cd、Cr、Cu和Mn在土壤中属于高水平污染，普遍高于最大允许水平（MPL）。使用危害商 (HQ) 的计算表明，食用所研究的蔬菜可能会对居民，尤其是儿童，带来重大的健康风险，由于 Tl、As 和相关有毒元素的含量升高。使用 Pb 同位素组成通过二元混合模型计算表明，炼钢活动造成了蔬菜中 35-80% 的 Pb 和 As 污染。要采取适当的整治措施，减轻农田污染，确保农产品的食品安全。
