Lead and cadmium were determined by graphite furnace atomic absorption spectrometry and arsenic via hydride vapour generation. All samples had arsenic and mercury contamination. Arsenic levels showed a range of 0.25−1.42 mg kg −1, which might be due to lack of national and international limits for arsenic in canned tuna fish.

Results of lead, cadmium and mercury analyses were compared with the standard specifications of Korea Food Standards Codex. As a result, high levels of Pb, Cd and Hg were detected in "cockle," "dried-squid" and "shark-meat." Acceptable intake for consumers was checked using provisional tolerable weekly intake values.
