From July 1994 to June 1995, a total of 64 fresh-iced spotted chub mackerelScomber australasicus (Cuvier) were sampled from Keelung and Su-ao areas,Taiwan. The contents of Hg, Zn, Cu, Ni, Pb and Cd in the dorsal meat, abdominalmeat and viscera were analyzed. The data showed that no relation existed betweenall the 6 heavy metal contents and the part of the fish, the maturity of thefish, the month or the area; however, the contents of Ni, Pb and Cd in theviscera were higher than those in the dorsal meat or abdominal meat althoughthose in the latter two parts were similar. All the samples were not or slightlycontaminated by Hg, Zn or Cu. However, it must pay attention on the fact thatthey, especially the viscera, might be contaminated by Ni, Pb and Cd.
