In this study, we investigated the relationship between environmental parameters (water and sediment) and benthic foraminiferal assemblages found in nearshore siliciclastic sediment in the Arabian Gulf. Nearshore marine water and sediment samples were collected from a beach on the Gulf of Bahrain located south of Al Khobar, Saudi Arabia. The water samples were analyzed for biochemical oxygen demand (BOD₅) and other chemical analyses. The sediment samples were tested for sediment oxygen demand (SOD) and heavy metal analysis. Results showed the BOD₅ levels were below the detection limit (<1 ppm), while the mean SOD value was 0.97 ± 0.08 g/m²·day. The water and sediments were unpolluted and free of eutrophic enrichment, while the sediment was anoxic. The two most common genera in the benthic foraminiferal assemblage, Ammonia and Elphidium, are typical of shallow water sandy substrates. This is the first reported comparison between SOD and benthic foraminiferal assemblages.

在这项研究中，我们调查了环境参数（水和沉积物）与在阿拉伯湾近岸硅质碎屑沉积物中发现的底栖有孔虫组合之间的关系。从位于沙特阿拉伯Al Khobar以南的巴林湾的一个海滩收集了近岸海水和沉积物样本。分析了水样品的生化需氧量（BOD ₅）和其他化学分析。测试了沉积物样品的沉积物需氧量（SOD）和重金属分析。结果显示BOD ₅含量低于检测极限（<1 ppm），而平均SOD值为0.97±0.08 g / m ²·日。水和沉积物未被污染，没有富营养化，而沉积物是缺氧的。底栖有孔虫组合中最常见的两个属是氨和El，是浅水砂质底物的典型特征。这是首次报道SOD与底栖有孔虫组合之间的比较。
