对印度南部内洛尔海岸沿着的底栖有孔虫种类进行了研究。研究区表层沉积物样品的分析表明，富集重金属（铬，铜，铅和锌）。环境对有孔虫已变得如此致命，以致目前在距海岸线不到5海里的等深线上能保存生活状态的有孔虫种类最少（4-7种）。仅接受农业和水产养殖排水的排水口样品显示重金属浓度略高于自然基线水平，并产生活有孔虫（10-15）。与水产养殖和农业排放口相比，工业排放口经常出现变形和异常标本，这表明：（a）底栖有孔虫对含重金属的工业废物更敏感;（B）农业和水产养殖废物对底栖有孔虫没有显著的伤害;（c）有孔虫试验的形态异常取决于污染物的性质。
A study of benthic foraminiferal species was carried out along Nellore Coast of South India. Analysis of surfacial sediment samples from the study area shows enrichment in heavy metals (Cr, Cu, Pb and Zn). The environment has become so lethal to foraminifera that minimal species number (4–7) can currently preserved in living condition in a depth less than 5-fth contour from coast. Samples from outfalls which receive only agricultural and aquacultural drainage water show heavy metal concentrations slightly higher to natural baseline levels, and yielding, living foraminifera (10–15). The frequent occurrence of deformed and abnormal specimens in Industrial outfalls, comparable to aquacultural and agricultural outlets reveal that (a) benthic foraminifera are more sensitive to industrial wastes containing heavy metals, (b) agricultural and aquacultural wastes do not significantly harm benthic foraminifera, and (c) morphological abnormalities of the foraminiferal tests depend upon the nature of the pollutant.
