In this work, the LIBS (Laser Induced Breakdown Spectroscopy) and ICP-OES (Inductively Coupled Plasma-Optical EmissionSpectrometer) technique applied to the determination of total concentration of some elements (Fe, Zn, Al, Mn, Co, Cr, Cu, Ni, Na,Mg, K, Ca) derived from soil samples of Marmara Sea. To support to the technique, LIBS data were compared with data have beenobtained on the same soil samples by application of Conventional Inductively Coupled Plasma Spectroscopy (ICP-OES). Thesimilarity of results obtained between the two sets of data suggested the potential applicability of the LIBS technique to the measurement of elements in soils. According to the study, it has been seen that the elements determined by ICP-OES analysis alsodetermined by LIBS method. It has the advantages of being faster than other traditional methods, being portable, having low analysiscosts, not being damaged and re-used during the analysis and short preparation period. However, the LIBS method is an important andpractical technique for the determination of elements of natural and anthropogenic origin. In the analysis made by ICP-OES method,the amounts of the elements in ppm are determined, while the results of LIBS analysis show the presence of the element only in %.According to LIBS method, Zn, Mn, Co, Cr and Cu concentrations vary according to each region. In this study, according to ICP-OESanalysis, Zn (42.2-111.7 ppm), Mn (163.2-581.1 ppm), Co (37.14-65.87 ppm), Cr (42.5-112.6 ppm), Cu (5.71-24.33 ppm), Ni ( 98.20-175.55 ppm), Al (16568.8-24850.9 ppm), Fe (20936.9-37397.9 ppm), Na (5223.4-12384.7), Mg (4800.4-7385.3 ppm), K (3290.8-5582.0) and Ca (42405.2-154577.0 ppm) ). LIBS analysis results showed that parallels Zn (0-22%), Mn (0-28%), Co (0-21%), Cr (0-23%), Cu (0-19%), Ni (%) 0-2), Al (67-78%), Fe (94-95%), Na (70-87%), Mg (82-90%), K (85-94%), Ca (66-%) 80). The LIBSmethod is an important technique for identifying elements enriched with anthropogenic factors and elements originating from naturalprocesses. The LIBS method can be used to determine the source of elements in marine or terrestrial environments. In addition, theLIBS method; It has also shown important results in the determination of toxic elements such as Mn, Cr, Co and Cu which increase inmarine sediment by anthropogenic factors.
