EVALUATING CONCENTRATION OF MERCURY RESIDUES IN CANNED TUNA

Abstract: Tuna fish has been consumed widely all around the world. Mercury poisoning threat is so high that some countries measure the mercury residues of the environment and foods continuously or intermittently. The aim of the present study was to search and review the findings from the scientific published literature studies focusing on concentration of mercury residues in commercial canned tuna. The results of the data search, remaining 12 articles  were suitable in this review. Concentration of mercury residues in canned tuna were determined in this study using Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma Emission Spectrometer, or Direct Mercury Analyzer (DMA-80). A large propotion of commercial canned tuna samples from different countries were analysed and found to have mercury residues that were within the acceptable range. Measuring the concentration of  mercury residues is essential based on public health aspect. According to EU announcement, the safe level of mercury in fish is 1 mg/kg. The US Environmental Protection Agency has set 0.5 mg/kg  for mercury. Based on Provisional Tolerance Weekly Intake set by JECFA (Joint FAO/WHO), PTWI is 0.5 mg/ kg for mercury.

Keywords: Concentration, heavy metals, mercury residues, canned tuna.
