Özet

This research investigated the transfer of potentially toxic metals through the agricultural food chain, from water and soil to maize, and subsequently to cow milk, at roadside (RS) and control site (CS) locations. Using atomic absorption spectrophotometry (AAS), the concentrations of Zn, Cu, Co, Mn, Mo, Fe, Pb and Cd were determined in samples of irrigation water, soil, maize and milk. Significant concentrations of Cd and Pb were detected in RS samples compared to CS samples, indicating anthropogenic inputs primarily from vehicle emissions. Milk metal concentrations at RS for Zn, Cu, Co, Mn, Mo, Fe, Pb, and Cd were 0.239, 0.001, 0.0011, 0.035, 0.001, 0.04, 0.0016, and 0.002 mg/L, respectively, while the corresponding CS concentrations were 0.288, 0.0005, 0.0008, 0.115, 0.001, 0.02, 0.0003, and 0.001 mg/L, respectively. The Contamination Factor (CF) and Bioconcentration Factor (BCF) indicated extensive transfer of trace metals in soils to maize. The health risk associated with the daily metal intakes, as assessed by the health risk dimensions (HRI), identified Cu and Cd as the most significant risks. The findings underscore the vulnerability of roadside agricultural systems to potentially toxic metal accumulation and emphasise the importance of continuous monitoring to safeguard food safety and public health.
