Characteristic levels of heavy metals in canned tuna fish
Concentrations of metals (aluminium, cadmium, lead and mercury) were determined from canned tuna commercialized in Canada and India, by inductively coupled plasma - optical emission spectrometer (ICP-OES) and direct mercury analyzer (DMA 80). Higher concentration of Al (1.806 to 3.161 µg/g) and Hg (0.60 to 0.62 µg/g) were found in tuna processed from India. Cd and Pb ranged from 0.020 to 0.025 and 0.011 to...
