| Abstract | ||
| Benthic foraminifera, unicellular marine protists, exhibit a globally extensive distribution, high population densities, and significant species richness. Their robust tests (shells) are readily preserved within sedimentary archives, providing a detailed historical record. Furthermore, their demonstrated sensitivity to environmental perturbations renders them valuable bioindicators in paleoenvironmental and modern ecological change studies. Benthic foraminiferal assemblages are increasingly employed as bioindicators of environmental disturbance, as their sensitivity to pollutants manifests in compositional shifts, providing valuable insights into ecosystem health. This study focused on assessing the impact of both organic and inorganic pollutants, noting that Ammonia tepida is recognized as a pollutiontolerant species. Ammonia tepida is consistently documented across numerous polluted sites, indicating its potential as a robust bioindicator species. The species' preference for fine-grained, organic carbon-rich sediments may explain its observed dominance in these impacted environments. Morphological abnormalities, including twinned or reduced chambers, coiled or uncoiled shells, surface protrusions, irregular suture lines, and test dissolution, are frequently observed in foraminiferal tests from polluted regions. Over the past decade, there has been a significant increase in laboratory culture studies aimed at elucidating foraminiferal responses to specific pollutants. These controlled experiments have facilitated improved differentiation between natural and anthropogenic environmental alterations. Furthermore, the Uvigerina jacksonensis, Bulimina jacksonensis, and Nonion scaphum are relevant to environmental studies. | ||
