This study investigates living benthic foraminiferal assemblages as bio-indicators of anthropogenic activities in a coastal area within the Gulf of Palermo (Sicily, Italy), affected by industrial and urban activities, and evaluates the environmental quality through the calibration of a Tolerant Species index (%TS). Sediments from 6 stations were sampled along a bathymetric transect from the coast to offshore. Sediment grain size, TOC, major, minor and trace elements and polycyclic aromatic hydrocarbons (PAHs) were compared to benthic foraminiferal assemblages and species at each station. Diversity and density of benthic foraminiferal assemblages were not affected by the presence of pollutants, while tolerant species increased with organic (TOC and PAHs) or chemical (As and Pb) concentrations. Moreover, the calibration of the %TS formula to >125μm foraminiferal assemblage, gives a detailed description of environmental quality along the transect, representing a good and sensitive tool to evaluate marine coastal environment.
本研究调查了生活在巴勒莫湾（意大利西西里岛）沿海地区受工业和城市活动影响的底栖有孔虫组合，将其作为人为活动的生物指标，并通过校准耐受物种指数（%TS）来评估环境质量。沿着从海岸到近海的测深断面，在6个站点采集了沉积物样本。将每个站点的沉积物粒度、总有机碳、主要、次要和微量元素以及多环芳烃（PAHs）与底栖有孔虫组合和物种进行了比较。底栖有孔虫组合的多样性和密度不受污染物存在的影响，而耐受物种随着有机（总有机碳和多环芳烃）或化学（砷和铅）浓度的增加而增加。此外，将%TS公式校准至>125μm有孔虫组合，可详细描述沿断面的环境质量，是评估海洋沿海环境的良好且敏感的工具。
