摘　　要：采集94个北部湾沿海不同区域、不同季节、不同品种的海产品，用微波消解．电感耦合等离子体质谱法测定砷、铅、汞、镉、铬、锡、锑、铜、铝等9种重金属元素的含量，以了解广西北部湾海产品是否受到重金属污染。测定结果表明，海产品中镉含量平均合格率为55％，应是污染所致，无机砷、铅、汞、铬、铜、铝含量平均合格率在890／扣96％之间，受污染程度较轻，而锡、锑含量合格率为100%，未受污染。To assess heavy metal pollution in seafood of Chinese Northern Bay, 94 seafood samples, collected tiom different regions, seasons and different varieties, were prepared with digestion. The contents of arsenic, lead, mercury, cadmium, chromium, tin, antimony, copper and aluminum were determined by inductively coupled plasma mass spectrometry. The results showed that, concedering cadmium content, only 55% samples were qualified. For inorganic arsenic, lead, mercury, chromium, copper and aluminum, 89%--99% samples were qualified. Detemaination of fin and antimony contents showed that 100% samples were qualified.
