Pollution analysis and ecological results of Gemlik (Bursa) - Bandirma (Balikesir) sea sedimas in the Southeast Marmara sea

Within the scope of this study, pollution analysis and ecological results of marine sediments between Gemlik (Bursa) and Bandırma (Balıkesir) in the South East Marmara Sea were studied. The average salinity values of the Marmara Sea between Gemlik and Bandırma are 22 per thousand and the salinity is less than our other seas. Core samples (Sediman) taken from Gemlik and Bandırma Bays are mostly low gravel, sandy silt-clay and silty clay. The geochemical analysis of the samples taken from these surfaces were evaluated by using libs and ICP-OES methods. In the evaluation, Enrichment Factor (EF), Contamination Factor (Cf), Pollution Loading Index (PLI), Ecological Risk Index, Pollution Index (PI), Geological Accumulation Index (Igeo) values were calculated. Foraminifers were used as bioindicators in the study. When the ICP-OES analysis results are evaluated with indices, it was determined that especially cadmium, nickel and zinc elements are not of shell origin and enrichment in Gemlik and its surroundings. Index calculations gave results that were overlapping with each other. It has been observed that there are mostly mineral mineralization, ship traffic and industry in the areas defined as dirty. In organic matter analyzes,% N,% TC,% IC and% TOC values were mostly obtained as <1. Locations with high organic matter ratios are especially clayey and silty anoxidant environments, and heavy metal contamination has been observed in these locations. A rich collection of foraminifera in its samples (Adolosina clarensis, Ammonia compacta, Ammonia parkinsoniana, Ammonia tepida, Cribroelphidium poeyanum, Cycloforina contorta, Elphidium crispum, Lobatula lobatula, Massilina gueltadyteriana, Miliolinella elongata, Pseudioculina, Rosalmoculina, Textularia bocki, Quinqueloculina leavigata, Quinqueloculina seminula, Quinqueloculina stalker, Quinqueloculina stelligera) were detected. As a result of the identification of the obtained foraminifera, it was determined that the foraminifera were 14 genera and 20 species.
