本文评估了尼日利亚尼日尔三角洲Akwa Ibom州两种无脊椎动物，eugeniae和Pachybolus ligulatus在有毒金属污染土壤中的生物指示潜力。本研究收集了分布在4个地方政府辖区的10个地点不同受影响和非受影响土壤的 eudrillus eugeniae 和Pachybolus ligulatus及其现场土壤样品。采用酸消解后的原子吸收光谱法对土壤和生物指示物中的有毒金属(Pb、Fe、Zn、Ni和Cd)进行了分析。利用地积指数(Igeo)测度土壤污染程度;生物积累因子(BAF)通过生物指标计算土壤对金属的吸收;以及多元统计，以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背景水平，并分为未污染至极重度污染。Pb、Fe、Zn、Cd在 eugenius ， Ni在Pachybolus ligulatus中的含量均为0.05水平。微生物吸收了所有的金属(BAF<1)，但 euudrilus eugeniae积累了Cd和Fe， Pachybolus ligulatus， Ni和Fe (BAF>1)。金属被聚为3个( eugenieudrilus )和2个(Pachybolus ligulatus)不同的组。 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.
