  • 摘要: 为研究安溪铁观音茶园土壤中重金属分布特征及污染程度，采用电感耦合等离子体质谱法（ICP-MS）分析测定了安溪8个乡镇的铁观音茶园土壤中9种重金属的含量， 运用地质累积指数法、富集系数法和潜在生态风险指数法评价重金属污染特征及潜在生态风险.结果表明，不同乡镇茶园土壤中重金属含量差异较大，重金属总平均含量顺序为Mn > Zn > V > Pb > Cr > Cu > Ni > Co > Cd，Mn、Zn、Co、Pb和Cd的总平均含量超过福建省土壤环境背景值.地质累积指数法和富集系数法评价结果均表明，各元素污染程度顺序为Cd > Pb > Zn > Mn > Co > V > Cu > Ni > Cr，其中，Cd为中度富集和偏中度污染，Pb、Zn、Mn为轻度富集和无污染，其他元素为无富集无污染.潜在生态风险指数法评价结果表明，Cd表现为较高潜在生态风险，其他元素表现为轻度潜在生态风险，各元素综合潜在生态风险为较高，Cd应成为安溪铁观音茶园土壤质量评价中重点关注的重金属.
    Abstract: To investigate the distribution characteristics and pollution degree of heavy metals in soils from Tieguanyin tea garden of Anxi county, contents of 9 heavy metals in the soils from Tieguanyin tea garden of 8 towns were determined by inductively coupled plasma mass spectrometry(ICP-MS). Geo-accumulation index, enrichment factor and potential ecological risk index were applied to evaluate the pollution degree and potential ecological risk of heavy metals. The results showed that the contents of the heavy metals in tea garden soils showed variation and the average contents of the heavy metals showed the order of Mn > Zn > V > Pb > Cr > Cu > Ni > Co > Cd. Mn, Zn, Co, Pb and Cd were enriched in the soils comparing to the background values in soils of Fujian Province. The results of pollution assessment by geo-accumulation index and enrichment factor revealed that the pollution degree of heavy metals showed the order of Cd > Pb > Zn > Mn > Co > V > Cu > Ni > Cr. Cd showed mild to moderate pollution and moderate enrichment. Pb, Zn and Mn showed non-pollution and mild enrichment. The assessment results of potential ecological risk index indicated that Cd showed considerable potential ecological risk and the comprehensive ecological risk of 9 elements was considerate. In summary, Cd should be the focus of heavy metals in the evaluation of soil quality of Anxi Tieguanyin tea garden.
