摘要:
茶园土壤重金属污染直接影响产茶区茶叶质量,进而影响人体健康. 以福建省泉州市安溪县产茶区表层土壤为研究对象,通过室内实验,综合分析茶园土壤中Pb、Zn、Cu、Cr、Ni、Co、Mn和Fe的含量分布特征,结合正定矩阵因子分解(positive matrix factorization,PMF)模型,探究重金属的来源. 结果表明:研究区红壤中Pb、Zn、Co和Mn平均含量分别为福建省土壤背景值的1.38、1.25、1.50和1.86倍,已存在明显的积累; 研究区土壤重金属污染程度较轻,除少数样点的Pb、Zn、Mn存在中度污染之外,其他重金属基本属于无污染或轻度污染; PMF模型结果显示茶园红壤重金属来自4种污染源,即交通源、矿业源、自然源和农业源,贡献率分别为21.89%、25.82%、27.76%、24.52%.
Abstract:
Heavy metal pollution in tea garden soil directly impacts the quality of tea leaves in tea-producing regions,consequently influencing human health. In this paper,the surface soil of a tea-producing area in Anxi County,Quanzhou City,Fujian Province,is the focus of the research. The distribution characteristics of Pb,Zn,Cu,Cr,Ni,Co,Mn and Fe in tea garden soil are comprehensively analyzed through indoor experiments. The study also utilizes the probability matrix decomposition(PMF)model to explore the sources of pollutants. The results indicate that the mean contents of Pb,Zn,Co,and Mn in the red soil in the study area exceed 1.38,1.25,1.50,and 1.86 times the background value of the soil in Fujian Province,respectively,indicating significant accumulation. The level of heavy metal pollution in the soil in the study area is relatively low. Apart from moderate pollution of Pb,Zn,and Mn at a few sample points,the other heavy metals are mostly categorized as non-polluted or lightly polluted. PMF modeling reveals that the heavy metals in the red soil of the tea plantation originated from four pollution sources:transportation,mining,natural factors,and agriculture,contributing 21.89%,25.82%,27.76%,and 24.52%,respectively.
