Özet

There is a volcanic area in Hatay, Turkey with currently limited agricultural activities; however, its ecological properties make it a plausible choice for protected fruit and vegetable production. The different soil properties of the area might be useful for plant growing in the future. In this study, we determined selected plant nutrients and heavy metal concentrations of eight soil and rock types from the realon. along with those of ten different species of fruits and vegetables representing the region's flora and agricultural activities. We found significant differences in all the micronutrients and heavy metal concentrations among the media samples. Overall, the highest concentrations were recovered from growing media. For example, one medium had the highest concentrations of Cu, Cd and Zn. Similarly, the plant samples had significant differences in micronutrients and heavy metal concentrations. Almond leaf samples were in the highest mean groups for Mg, Na, Fe, Al and Cr, while cucumber had the highest values for Zn and Ni. The highest Pb levels were recovered from uncultivated olive. Comparisons of our results to those of others in the related literature indicated that only two of our results were above the accepted levels: the almond Fe and holy oak B concentrations. In conclusion, our samples from the volcanic area in Hatay were not dangerously contaminated with heavy metals, and utilization of this area for agricultural purposes poses no apparent threat.
