In this study, the concentration of heavy metals in fruit juices available in Tobruk city, Libya, was estimated to assess the potential health risks associated with their consumption. Samples of commonly consumed juices were collected from local markets. Using atomic absorption spectroscopy (AAS), levels of heavy metals such as lead (Pb), cadmium (Cd), mercury (Hg), nickel (Ni), cobalt (Co), chromium (Cr), manganese (Mn), iron (Fe), copper (Cu) and zinc (Zn) were determined. The absence of cadmium, cobalt, chromium and mercury in all samples is reassuring, indicating compliance with safety standards in the production processes. However, the presence of varying levels of copper, manganese and lead raises concerns about potential health risks associated with consumption. The significantly high concentration of iron (51,360 mg/L) is particularly worrying, as many samples exceeded the safety limits set by international health organizations. These results raise significant concerns about food safety and public health in Tobruk, highlighting the need for regular monitoring and regulatory measures to mitigate the risk of contamination in fruit juices.
