Abstract

BACKGROUND The present study investigated Pb, Cd and As concentrations in canned tuna, tuna steak, rainbow trout, smoked mackerel, and Baltic and Atlantic cod, as well as Atlantic salmon. The aim was to spot check the quality of the most commonly purchased types of fish that are available for sale in most common supermarket chains throughout the Poland, as well as to determine potentially less contaminated sources of fish available for retail. A dry ashing digestion protocol followed by inductively coupled plasma mass spectrometry analysis was employed to achieve a better recover of heavy metals and As from fish muscle tissues. RESULTS The cumulative concentration of metals and As in fish muscle tissue decreases in order: farmed Atlantic salmon > mackerel > Baltic cod > rainbow trout > canned tuna fish > Atlantic cod > yellowfin tuna steak. It was found that canned tuna from Central and Eastern Pacific Ocean were more contaminated than tuna from East and West Indian Ocean, Baltic cod was significantly more contaminated than cod from North-East Atlantic. Smoked mackerel from North-East Pacific Ocean is three times more contaminated than mackerel from Northern North Sea. All fish, except for yellowfin tuna steak, should not be intended for retail because they exceed maximum levels for Cd and Pb. CONCLUSION Consuming only one serving (140 g) of Baltic cod exposes one to 51% of the daily acceptable Cd intake, while the same portion of canned tuna and smoked mackerel from the Pacific Ocean deliver 69% and 72% of this element respectively. The most cadmium is consumed with smoked mackerel from the North Sea, comprising as much as 162% of the daily acceptable dosage . (c) 2020 Society of Chemical Industry
