布鲁卢斯泻湖的重金属污染源主要是磷肥、污水和渔船溢油，已鉴定的底栖生物有Adelosinacarinatastriata（Wiesner）、Quinqueloculinabosciana（d'Orbigny）、Quinqueloculinabsculum（Linnaeus）、Ammoniumtepida（Cushman）和Elphidiumunculatum（Terquem）。tepidais是泻湖中最具优势的物种。它占Burullus泻湖底栖有孔虫总组合的97%以上，反映了对极低盐度的耐受性。随着镉浓度的增加，A. tepida表现出很大的形态变异性和记录的形态异常显示高的螺旋给予螺旋凸测试，额外的室，异常的室形状和大小，扭曲测试与延长的旋转轴和复杂的畸形，其中E。漏斗状肿瘤显示额外的方解石分泌（肿瘤）。
Sources of heavy metals pollution in the Burullus Lagoon include phosphate fertilizers, sewage and oil spills from fishing boats.The benthic species identified in this lagoon areAdelosina carinata striata(Wiesner),Quinqueloculina bosciana(d'Orbigny),Quinqueloculina seminulum(Linnaeus),Ammonia tepida(Cushman),Elphidium excavatum(Terquem).A. tepidais the most dominant species in the lagoon. It constitutes more than 97% of the total benthic foraminiferal assemblages reflecting tolerance to the very low salinity in the Burullus Lagoon.The intensity of deformation was severe exhibiting a peculiar change in the coiling direction inA. tepidawith increase in cadmium concentration.A. tepidaexhibited a great morphological variability and the recorded morphological abnormalities show high spire giving the spiroconvex test, additional chamber, aberrant chamber shape and size, twisted tests with elongated axes of rotation and complex deformities, whereasE. excavatumshowed additional calcite secretion (tumors).
