In this work, the LIBS (Laser Induced Breakdown Spectroscopy) and ICP-OES technique has been applied to the determination of total contents of heavy metals (Fe, Zn, Al, Mn, Co, Cr, Cu, Ni, Na, Mg, K, Ca) in soil samples of Marmara Sea. In order to validate the technique, LIBS data were compared with data obtained on the same soil samples by application of conventional Inductively Coupled Plasma ICP spectroscopy. The partial agreement obtained between the two sets of data suggested the potential applicability of the LIBS technique to the measurement of heavy metals in soils.According to the results, it was seen that the elements determined by ICP-OES analysis were also determined by LIBS method. The LIBS method is an important and practical technique for determining the elements that are enriched with anthropogenic factors as well as the elements resulting from natural processes.

“…As can be seen in Figure 6, TOC values were higher in the Küçükkuyu region (10.35-20.36 g/kg) than Dikili (2.71-12.6 g/kg) and Güre (8.14-16.4 g/kg). In terms of heavy metal concentrations, these sample points represent a clean environment when compared to the Pollution Index (PI) map made by Yümün and Önce (2017). In the Küçükkuyu, Dikili, and Güre regions, it was observed that the terrestrial and marine nitrogen sources were similar over a long period of time.…”

In this study, sediment samples were taken at three different points in Edremit Bay at different depths from the sea floor. In Edremit Bay, it was investigated whether the pollution was marine or terrestrial. According the results of measurement of TOC (Total Organic Carbon) values have been yielded results between 10.35-20.36 (Küçükkuyu), 8.14-16.40 (Güre), and 2.71-12.60 g/kg (Dikili) in the marine sediments. The fact that first and second regions are susceptible to mountainous and intra-continental erosion (sedimentation 5.743 and 7.509 mm/year) increased the TOC value. The highest TOC/TN ratio (12.33-46.89) was found in the second region. No linear change in TOC and TOC/TN (Total Nitrogen) ratios was observed at all three points depending on the depth. At results of compared all carotes, the low TOC/TN (2.82-14.48) ratio have been observed in the BH1 carotes, probably the result of small stream beds and low intra-continental erosion. This study shows that TOC and TOC/TN ratios in different parts of Edremit Gulf show inconsistency and this inconsistency arises not only from the marine contribution their natural organic matter, but also from the continent.

“…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.
