The aim of this study was to quantify the pollution level of toxic elements, their ecological risk and human health hazard in the agricultural soil of Tiantai County, Zhejiang province. A total of 2651 soil samples were collected and analyzed for 13 toxic elements using different analytical techniques. The concentration of Cd, Pb, Hg, Mn, and Zn was higher than the Zhejiang background value in more than 50% of samples. Enrichment factor showed that As, Cd, Hg, Mo, Pb, Se, V, and Zn were anthropogenically loaded and most of the toxic elements showed poor spatial distribution. Nemerow pollution index showed that Chicheng, Shiliang, Pingqiao, Tantou, and Youngxi towns were seriously polluted by toxic elements. Principal component analysis and cluster analysis showed that Co, Cr, Ni, and Cu, whereas, Cd, Pb, and Zn shared the similar source of origin. A large area of Tiantai County experiencing moderate to a serious level of pollution but most of the toxic elements exhibit low risk to the environment except Cd and Hg. Furthermore, children were more prone to health hazards than adults with following order: As > Cr > Pb > Mn. Overall, As and Pb were prominent for pollution, ecological risk, and human health hazards.

这项研究的目的是量化浙江天台县农业土壤中有毒元素的污染水平，其生态风险和人类健康危害。总共收集了2651个土壤样品，并使用不同的分析技术分析了13种有毒元素。在50％以上的样品中，Cd，Pb，Hg，Mn和Zn的浓度均高于浙江背景值。富集因子表明，人为负载了砷，镉，汞，钼，铅，硒，钒和锌，大多数有毒元素的空间分布较差。Nemerow污染指数显示，赤城，石梁，平桥，坦头和Youngxi镇受到有毒元素的严重污染。主成分分析和聚类分析表明，Co，Cr，Ni和Cu具有相似的来源，而Cd，Pb和Zn具有相似的来源。天台县大面积污染程度中等至严重，但除镉和汞外，大多数有毒元素对环境的风险均较低。此外，按以下顺序，儿童比成人更容易危害健康：As> Cr> Pb> Mn。总体而言，砷和铅在污染，生态风险和人类健康危害方面表现突出。
