The aim of this study is to identify and thematically map potentially toxic heavy metal elements in soils in order to ensure sustainable use of intensively cultivated soils and to protect food safety. Methods and Results: In this study, 165 soil samples (City center, 40; Kadirli, 83; Düziçi, 25; Hasanbeyli, 6; Toprakkale, 10 and Bahçe, 1) were taken from the areas representing the agricultural production lands in the province of Osmaniye and its districts. It was determined that the total Mn, Fe, Ni, Cd and Cr in the toxic element results of these samples were above the specified limit values. Conclusions: This may be due to the fact that the region is at the foot of the Taurus Mountains, the serpentine in the bedrock and/or some heavy metals such as Cr and Ni are high due to the mineralization of chromium. However, it can be said that Cd accumulation may be caused by phosphate fertilizers, since intensive fertilization is made. In the Fe analysis that can be taken in the soils taken from the study area, 92.7% of the iron content of the soils is less; 3.7% is medium; 3.6 of them were high.
Significance and Impact of the Study:The results obtained by carefully monitoring the passage of these metals to plants, animals and humans through the food chain through researches to be carried out, whether it is important for food safety or not, the data obtained as a result of analyzing suitable extractors and selecting the extractor with correlation calibration studies, whether it will be toxic or not with a different research. Needs to be clarified. This study is a case study and a study that reveals the possible heavy metal potential of the rocks in question. However, whether it will have an antagonistic effect on the transition to the plant by dissolving or the intake of other elements will be possible by investigating the extractable dose with various kileyt solvents.
