Abstract:
To assess heavy metal pollution in seafood of Chinese Northern Bay, 94 seafood samples, collected from different regions, seasons and different varieties, were prepared with microwave-assisted 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. Determination of tin and antimony contents showed that 100% samples were qualified.
