dc.description.abstractThis thesis focuses on heavy metal contamination in fresh produce sold in Debrecen, Hungary, with a specific focus on apples, carrots, and lettuce. The concentrations of lead (Pb), cadmium (Cd), and chromium (Cr) were measured and compared to European Union safety limits by using Graphite Furnace Atomic Absorption Spectrometry (GFAAS). The results showed that apples from Kispiac and carrots from Aldi contained lead levels exceeding EU thresholds, while cadmium and chromium remained within safe ranges. A health risk assessment based on the Target Hazard Quotient (THQ) indicated that Kispiac apples posed a potential health risk due to lead exposure. In addition, nutrient analysis revealed excessive potassium and sodium levels in some samples are due to unsustainable farming practices. The study highlights the urgent need for stricter monitoring, improved agricultural management and sustainable farming practices to ensure food safety.
