Determination of Heavy Metal Distribution of Yenikapı (Istanbul) Sea Sediments Using Libs Method

Abstract

In this study, the toxic element concentrations of the marine sediments of the Yenikapı (Istanbul) coast were determined by LIBS (Laser Induced Plasma Spectroscopy) technique. Six samples of core sediment were taken from the region for analysis. The samples were brought to the laboratory and made ready for analysis. The area is open to pollution from boat waste, fishing waste and domestic waste water. The LIBS method has advantages such as faster results than all other conventional methods, being portable, low analysis costs, not being damaged of sediments, reused after analysis, and short preparation process, and it is an important and practical technique for determining elements of natural and anthropogenic origin. The method is used in many fields such as environment, geology, forensic medicine, food, health and it has been found to give accurate and fast results.The analysis results obtained with the LIBS method give the probability of the elements in that sample as a% value. Analysis does not provide the amount of elements in the sample. Although this is seen as a disadvantage, this method gives very useful results for practical and preliminary research. In this study, ECCO®2 branded LIBS machine was used. The heavy metal distribution of six sediment samples taken from the Yenikapı region is shown by graphs. According to LIBS analysis results, it was seen that the distribution of elements such as Fe, K, Li, Sr, Zn and Mg was higher in percentage. All elemental data obtained were examined by the basic component analysis (PCA) method in the literature. Thanks to this analysis, the contribution of each variable to the content of the sediment has been tried to be revealed. Analyzes showed 83.39% discrimination for six samples taken from the region. It has been determined that Fe, Al, Mn, Ca, K, Na and Zn elements contribute more in the composition of sediment samples. The contents of six samples taken from the region were found to be similar. Elemental compositions of marine sediments were revealed in the study area. As a result of the analysis, it was seen that LIBS method can be used on sediment samples.
