A flame atomic absorption spectroscopy (AAS) and spectrophotometric (UV-VIS) determination of the formation of complexes with copper and chromium were used to identify heavy metals in four types of tuna cans (Dwarf, Al-Wafa, Skipjack and Marina) sold in the markets of the city of El-Bayda, Libya. The study concluded that, compared to the Libyan standard specifications for both local and imported tuna cans, the components specified for analysis (Cu, Pd, Cd) are present in tuna meat in fairly excellent quantities in the following ratios: (0.2340, 0.0589, 0.2378 parts per million) respectively. The salinity of the brine is given as a percentage (0.82%, 1.16%, 0.67%, 0.60%), respectively. The tuna pH levels are (6.02, 5.81, 5.62, 5.80), respectively. Therefore, we can draw the conclusion that all of the tuna cans tested in this study complies with Libyan standard specifications. This is because Libyan centers that specialize in product examination are closely monitoring the products to make sure they are free of heavy elements or within permissible limits so that they don't contain any pathogens or trace elements when they reach consumers.
