水体中的有毒金属污染对生活在发展中国家的人们的健康构成威胁。位于中国一些矿山附近的未经处理的矿山废物可能会造成水污染，最终导致各种疾病。本研究的目的是评估位于贵州省西南部汞-铊矿化区的兰木场溪流中隐阿米巴群落对地下水、溪水和水生苔藓中有毒金属污染的响应，中国。测定了三种苔藓植物的汞、砷、镉、铊、铜、锌、铅的含量。汞、砷、铜、铅和锌的平均苔藓浓度显著高于溪水，而变形虫物种丰富度和丰度则显著低于污染组。然后我们研究了有毒金属和变形虫之间的相关性。总物种丰度与汞、铜浓度呈负相关。结果表明，变形虫对有毒金属污染非常敏感，水生苔藓是痕量金属的生物蓄积者，同时也显示出潜在的微生态系统健康风险。
Toxic metal pollution in bodies of water is a source of danger to the health of people living in developing countries. The untreated mine wastes located near some Chinese ore mines may cause water pollution, which ultimately results in various diseases. The aim of the present study is to assess the response of testate amoebae communities to pollution by toxic metals in groundwater, stream water, and aquatic bryophytes in Lanmuchang stream located in the Hg–Tl mineralized area in southwestern Guizhou Province, China. Measurements were made of the levels of Hg, As, Cd, Tl, Cu, Zn, and Pb in three mosses:Hyophila propagulifera,Rhynchostegium riparioides, andHygroamblystegium tenax. Mean moss concentrations of Hg, As, Cu, Pb, and Zn were significantly higher than stream water values and testate amoebae species richness and abundance were significantly lower in the ‘polluted’ group. We then studied the correlation between toxic metals and testate amoebae. The total species abundance is correlated negatively to Hg and Cu concentrations. Our results indicated that testate amoebae are sensitive to toxic metal pollution and aquatic bryophytes are bioaccumulators of trace metals, and results also showed potential microecosystem health risks.
