自1994 年 7 月至 1995 年 6 月，按月赴基隆或蘇澳採購水冰的生鮮花腹鯖，共 64件樣品，分別測定其背肉、腹肉和內臟中汞、鋅、銅、鎳、鉛和鎘等 6 種重金屬之含量。這些重金屬之含量，大致上與魚體部位、魚體大小 (肥滿度)、月份或地區無關；但是內臟的鎳、鉛和鎘之含量高於背肉或腹肉者，而後二者則相近。全部樣品的汞﹑鋅或銅之污染程度很低，但鎳、鉛和鎘之污染程度較高，值得注意。

From July 1994 to June 1995, a total of 64 fresh-iced spotted chub mackerel Scomber 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.
