“…The reason for this is thought to be industry and ship waste. Another important reason why the gross alpha and beta concentrations are generally high is that the fertilizers are used in agriculture that contain uranium, thorium and their decomposition products and natural 40 K [20].…”

Background and anthropogenic ionizing radiations are main sources of environmental radioactivity exposing human beings. Background radiation occurs as a result of cosmogenic and terrestrial radiation, while anthropogenic origins are man-made radiation. In this context, gross alpha and beta activity of sea sediment samples collected at 7 different stations in the research region (Şarköy and Mürefte) were analyzed using the low-background counter (Berthold, LB 770 10-channel α−β low-level counter). Also, the relationship between the abundance of radioactive isotopes and alpha and beta activity were discussed in this paper. As a result, the average gross alpha and beta activity was determined as 218.18  14.9 Bq kg -1 and 579.00  23.9 Bq kg -1 , respectively. Maximum gross alpha value in investigation area 301  15.9 Bq kg -1 (Şarköy Port), and the lowest value is 989  16.5 Bq kg -1 (Şarköy Port). When these values were compared with Bosna River results, both gross alpha and gross beta values were found to be high [3,4]. The main reason why gross alpha and beta concentrations are generally high is that the fertilizers used in agriculture contain uranium, thorium and their degradation products and natural 40 K.

“…Approximately 0.1 after plasma formation on the sample, the first ionic diffusion followed by atomic diffusion from the elements could be detected. Calibration curves were then drawn when determining the concentration of any element in the sample, and the slopes of these curves provided information about the sensitivity of the method (Castle vd., 1998;Kam & Önce, 2016;Rusak vd., 1997;Song vd., 1997;Yümün & Önce, 2017). In the present study, a UK origin Ecco brand LIBS device was used (Yümün at al., 2019).…”

The present study aimed to determine heavy metal pollution in the Izmir Karaburun region of Turkey by analyzing the marine sediments within the Izmir Karaburun peninsula. Sediment samples were taken using a drilling method from six different regions on the peninsula and analyzed using laser-induced breakdown spectroscopy (LIBS). The percentage of the elements in the samples that matched the standard elements described in the device were determined. The results showed that potassium (K) with a 97% matching percentage and iron (Fe) with a 94% matching percentage was intensive in six different regions. In the first, fourth, and sixth regions, silver (Ag), which is a frequent heavy metal, was found at a high incidence of 50% as regards that in other regions. The results of these analyses were parallel to each other in six different regions in the Izmir Karaburun peninsula, and amount of possibly toxic heavy metals were found. When the LIBS conclusions were compared with the conclusion found in the literature, the existence of some elements, such as mercury (Hg), lead (Pb), and arsenic (As), which are known to be toxic elements and a danger to human health, were found in only trace amount; as a consequence, we supposed that there is no heavy metal pollution that could pose a hazard to human health and marine ecosystems within that region.

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.
