Investigation of Potentially Toxic Elements in Agriculture Soil : Greenhouse and Open-field Farming in Türkiye

Sammanfattning: Greenhouse food production has intensive fertilizer practices, and it leads to contamination in the soil and food chains. This study investigated the potentially toxic elements (As, Pb, Zn, Cd, Cr, Cu, and Ni) (PTE) in agriculture soil and their bioaccumulation by dragon fruit and banana. Different fertility tests are conducted to see if there is a correlation between PTEs and fertilizers. CHNS/O analyzer was used to determine organic carbon and nitrogen concentration in the soil. Besides, organic and inorganic phosphorus amounts were analyzed to detect the amount of fertilizer input. Elemental analysis was conducted with ICP-MS. The amount of N, P, and K and PTEs compared and discussed to source the PTEs. Excessive fertilizer practices were acquired, and possible reasons and results were discussed. Besides, the investigations have revealed that concentrations of potentially toxic elements in greenhouse and open-field farms in Gazipaşa/Turkey are below the environmental standards in the soil and fruit samples. Organic farming practices are more dominant than inorganic farming practices in the sampling stations.
