... Methods of detecting marine pollution over time are the subjects of active research with an increasing global awareness about environmental problems. Numerous studies dealing with the relationship between foraminifera and pollution have considered trace metal as a significant variable acting on ecosystem with a notable influence on foraminiferal distribution (Barut et al. 2011;Barut et al. 2013;Bergin et al. 2006;Burone et al. 2006;Donnici et al. 2012;du Châtelet et al. 2011;Yalçın et al. 2008). ...
The benthic foraminiferal community is an excellent bio-indicator of pollution in coastal and marginal marine settings. Their abundance, diversity and its relationship with environmental parameters, viz. grain size, organic carbon (Corg) and trace metals concentration, from the surface sediment layer of the southwestern shelf of the Bay of Bengal, have been used to understand the marine pollution in this study. A total of 32 surface sediment samples were collected at various water depths.The samples were analysed for grain size distribution, organic matter (OM), foraminiferal and trace metals studies. Statistical analyses such as correlation matrix, PCA (Principal Component Analysis) and cluster analysis show that the foraminiferal species composition is significantly influenced by the organic carbon (Corg), Co, Pb, Zn, Cr, and Ni concentrations. The dominance of stress-tolerant species, viz. Ammonia beccarii, Ammonia tepida, Nonion faba, Bulimina marginata, Bolivina robusta, Elphidium craticulatum and Elphidium advenum, as well as less species diversity, demonstrates the elevated Corg and trace metal pollution in the marine environment.
... In this assemblage, another noteworthy feature is abundance of benthic foraminifera especially Peneroplis tests displaying extreme morphological disorders. The recent sediments consist of light gray sands in the other studied areas, and a small number of partly colored or colorless benthic foraminifera are observed in the upper levels (Meriç et al., 2012a,b;Barut et al., 2013;Yümün et al., 2016). Ammonia compacta Hofker, A. parkinsoniana (d'Orbigny), Challengerella bradyi Billman, Hottinger and Oesterle, Elphidium complanatum (d'Orbigny) and E. crispum (Linn e) are the dominant species in this assemblage. ...
In coastal parts of the study areas, heavy metals containing ground water flows along the faults and fractures and reaches at sea. In these contaminated waters, morphologically abnormal individuals of the affected meiofauna (benthic foraminifera, ostracod, mollusc) can be found. Three cores were taken from the seafloor in the four separate stations that are located in NW of Ayvalık village, around Alibey and Maden islands, and one core of each three core groups was studied in order to investigate the aforementioned morphological affects on the recent meiofauna, which have been inhibited in those contaminated waters. Lead, manganese, hematite and limonite deposits with small reserves were present in Alibey, Maden and Küçük (Small) Maden islands. Morphological changes and coloring were observed in tests of large number of Peneroplis, Lobatula, Ammonia and Elphidium samples collected from these areas. This observation vindicates impact of heavy metals onto the foraminifera assemblages. Heavy metals and other chemical and radioactive elements found in the surrounding country side have been naturally transported into the adjacent sea water during the past and present. The aim of this study is to figure out the effects of the chemical and radioactive elements, which were carried from the land on the meiofaunal (benthic foraminifera, ostracod and mollusc) assemblages.

Calcareous and agglutinated benthic foraminiferal diversity was investigated in the central Northern Aegean Sea. A total of 18 samples were collected along a neritic to mid-bathyal transect in Saros Bay at water depths ranging from 15 to 500 m. This study reveals a very highly diversified benthic foraminiferal fauna composed of 267 species belonging to 115 genera. Benthic foraminiferal taxa varied along the depth transect, and it is possible to recognise benthic foraminiferal assemblages typical for different bathymetric ranges. An inner–middle neritic assemblages (ca.
The study area consists of wetlands and semi-wetlands (saltpan and salt lakes) that are separated from the Gulf of Saros in the northeastern Aegean Sea by a littoral cordon. Twenty-four samples were collected from the Enez Salt Lake; Dalyan, Enez Gala, Kuvalak, Isik, and Tasalti Lakes; Vakif and Erikli Saltpans; and Karagol Lagoon. The overall distribution of the sediment sizes reveals that they consist predominantly of mud and sand and a mixture of mud, sand, and gravel. The average proportion of gravel size particles is 8.36%. Feldspar and mica are abundant in sand and gravel-sized materials. Ecological conditions of these coastal areas were assessed on the basis of ostracod assemblages that can be considered as useful bioindicators and depend on water depth, temperature, and salinity. In this context, the effects of physical and chemical properties of the environment, geochemistry of the sediment, and anthropogenic impact on the meiofauna, in particular ostracoda, was here evaluated. Cyprideis torosa Jones, a cosmopolitan species of ostracoda, was found in salt lakes. Other species of ostracoda were shown to be affected by environmental conditions. The toxicity of some heavy metals in the saltpans, salt lakes, and hypersaline lagoons was evaluated. Lake Dalyan and Erikli Saltpan display high toxicity for Cu and Cd levels. The distribution of hydrocarbon pollution of terrestrial origin was determined.
