对尼日利亚尼日尔三角洲地区阿夸伊博姆州两种无脊椎动物Eudrilus eugeniae (蚯蚓)和Pachybolus ligulatus (千足虫)在受有毒金属污染土壤中的生物指示潜力进行了评价。本研究收集了eugenae 和Pachybolus ligulatus，并在4个地方政府辖区的10个地点收集了不同受影响和未受影响土壤的土壤样本。采用原子吸收光谱法对土壤和生物指示生物中的有毒金属(Pb、Fe、Zn、Ni和Cd)进行酸消化分析。利用地积指数(Igeo)衡量土壤污染程度;生物积累因子(BAF)通过生物指标计算土壤对金属的吸收量;通过多元统计来确定金属与污染源之间的相互关系。所有土壤中金属含量均高于本底水平，属于未污染至重度污染。Pb、Fe、Zn、Cd在尤金珠菌中高于0.05水平，而Ni在舌孔珠菌中高于0.05水平。生物吸收所有金属(BAF>1)，但 euudrilus eugenae 积累Cd和Fe， Pachybolus ligulatus积累Ni和Fe (BAF>1)。金属聚为3个类群(Eudrilus eugeniae)和2个类群(Pachybolus ligulatus)。 Two principal components extracted, each for Eudrilus eugeniae and Pachybolus ligulatus accounted for 64% and 72% of total variations, respectively. The invertebrates exhibited varying levels of affinity in metals uptake. Eudrilus eugeniae appeared to accumulate Pb, Fe and Cd more, and could serve as a better bio-indicator for monitoring these metals. Pachybolus ligulatus accumulated 3-folds more Ni, and could provide a monitoring tool especially in agriculture, in the Niger Delta Region of Nigeria, plagued by crude oil pollution of its land and water bodies.
