“…In such monitoring, sediments are used as bioindicators for marine environments. The Sea of Marmara is exposed to chemical and biological pollution from various sources, including a dense population, excessive industrial activities, intense maritime traffic in the straits, marine accidents, and agricultural activities (1)(2)(3)(4)(5). This influx has caused pollution, not only in the Marmara Sea, but also in neighboring seas and rivers (1,6).…”

In this study, heavy metal concentrations (Ca, Mg, Hg, As, Sb, Ag, Al, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, Zn, Ti, Th, U, Mo, Cd) amounts were measured by examining marine sediment samples obtained from the coasts of the Izmit Bay Altınova shipyards region. The natural and anthropogenic pollution levels of the region were revealed by the analysis of sediment samples. The extent to which the marine ecosystem may have been affected by the shipyard activities that have been actively carried out in the region for the last ten years was also investigated. Heavy metal analyses of sediment samples were carried out by the XRF method. In addition, the morphological and surface features of the sediment grains were obtained by SEM analysis, and the element contents of seawater samples obtained from the region were determined with an ICP-OES device. The heavy metal pollution level of the region was revealed by evaluation of the data obtained as a result of the analysis. The results of the XRF analysis showed that the heavy metals, which are toxic for humans, such as cadmium (max 17.984 ppm), lead (max 31.302 ppm), nickel (max 71.725 ppm) and arsenic (max 13.852 ppm) were detected. According to the results of elemental analysis with ICP-OES, Hg, As, Sb, Ag, Al, Co, Cr, Ni, Pb, V, Ti, U, Mo, and Cd were below the measurable limit.

“…It has been shown that the effects of pollution were higher in the regions close to settlements, harbors or sewage discharges compared to other regions(Wang et al 2021;Murphy et al 2016). Yümün et al (2021) has stated that the ship tra c is very intense and pollution index values are high in Gemlik, Narlı and Kurşunlu. These researchers have also pointed out that the pollution is originated from industry and agriculture as well as ship tra c especially in Gemlik and Kurşunlu.…”

Currently, the microplastic pollution is a common phenomenon in the wold wide. Microplastic density has enhanced and accumulated over decades in the aquatic ecosystems and caused many physiological problems in living organisms. Also, toxicity of microplastics increases by providing a surface area to the other polutants. In this study, we aimed to evaluate and characterize the microplastic pollution in the sediment and commercial fish species in the Gemlik Bay, Marmara Sea. Our results showed that the highest accumulation of microplastics in the sediment is at the station in the Gemport Harbor (9733.3 pieces.kg-1) and the lowest accumulation is at the Kurşunlu offshore (3333.3 pieces.kg-1). On the other hand, the highest microplastic accumulation per individual was in the gills of Synapturichthys kleinii (Risso, 1827) (14.5 pieces.ind-1) and the lowest in Diplodus annularis (Linnaeus, 1758) (0.33 pieces.ind-1). The highest accumulation was indicated (8.75 pieces.ind-1) in the gastrointestinal tract of Chelidonichthys lucerna (Linnaeus, 1758), but the lowest accumulation is in that of D. annularis (0.88 pieces.ind-1) species. The fiber-type particles were the most determined microplastics in sediment and fish samples. Micro-Raman Spectrometer was revealed that Polyvinyl chloride (PVC) and polypropylene (PP) were dominant in the sediment, and polyoxymethylene (POM) and polyphenylene sulfone (PPSU) polymers were dominant in fish species. Our study showed that more intense microplastic pollution were determined in the Gemlik Bay then the other locations of Marmara Sea. Also our results suggested that there was a pollution pressure on the ecosystem and that the requirement of controlling the ports and discharge waters underlined.
