Abstract

The aim of this study is to investigate radioactive pollutants from pollution loads transported from the Black Sea to the Aegean Sea by the Turkish Straits System and their effects on microfauna (benthic foraminifer and ostracod) assemblages. In the study, the effects of gross alpha and beta activity on the species number, species diversity, dominant species and species richness of benthic foraminiferal and ostracod assemblages were investigated in 16 bottom sediments taken from different depths in the Golden Horn, Bosphorus and Dardanelles straits. In the studied sediment samples examined 61 genera and 64 species of benthic foraminifera, 23 genera and 26 species of ostracoda were identified. In addition two migratory foraminifera species were observed as Spiroloculina antillarum of Atlantic-Pacific origin and Peneroplis pertusus of Indo-Pacific origin. A relationship between the abundance of microfauna and high gross alpha and beta values was found in the Dardanelles samples, but not in the Bosphorus and Golden Horn samples. In this study, the highest radioactivity value was observed in the deepest bottom sediment samples. Consequently, the gross alpha and beta values were seen to be close to each other in the Dardanelles Strait and Golden Horn samples, and they had a broad-spectrum in the Bosphorus samples.

博斯普鲁斯海峡、达达尼尔海峡和金角湾沉积物放射性特性和微型动物证据的评估

本研究的目的是调查通过土耳其海峡系统从黑海输送到爱琴海的污染负荷中的放射性污染物及其对微型动物(底栖有孔虫和介形虫)组合的影响。研究了总α和β活性对金角海峡、博斯普鲁斯海峡和达达尼尔海峡不同深度16种底栖有孔虫和介形虫组合的物种数量、物种多样性、优势种和物种丰富度的影响。在研究的沉积物样品中，鉴定出底栖有孔虫61属64种，介形虫23属26种。此外，还发现了大西洋-太平洋起源的反尖螺虫和印度-太平洋起源的百日鸡两种迁徙有孔虫。在达达尼尔海峡样品中发现了微动物的丰度与高总α和β值之间的关系，而在博斯普鲁斯海峡和金角海峡样品中则没有。在本研究中，在最深的底部沉积物样品中观察到最高的放射性值。因此，在达达尼尔海峡和金角海峡样品中，总α和β值接近，在博斯普鲁斯海峡样品中，它们具有广谱。
