A total of 47 species of foraminifera were identified in this study, of which 12 were morphologically abnormal. In the low-impact zone, the species diversity index (</span><em>H′</em>) was higher. TPH and PAH concentrations were positively associated with abnormal species. Pollution-resistant foraminifera species include <em>Ammonia tepida</em>, <em>Elphidium discoidale</em>, and <em>Quinqueloculina lamarckiana</em>, while opportunistic foraminifera include <em>Pararotalia curryi</em>, <em>Nonionella stella</em>, <em>Rosalina globularis</em>, and <em>Spirillina vivipara</em><span>. PAHs and heavy metals were adversely correlated with foraminiferal abundance, while TPH was positively correlated. To assess the response of the <a href=\"/topics/earth-and-planetary-sciences/benthic-ecosystem\" title=\"Learn more about benthic ecosystem from ScienceDirect's AI-generated Topic Pages\" class=\"topic-link\">benthic ecosystem</a> to hydrocarbon pollution, indices such as the Foraminiferal Index of Environmental Impact (FIEI), Exponential (</span><em>H′</em><sub>bc</sub>) index and the Foraminiferal Abnormality Index (FAI) were used as environmental health proxies.
