Abstract: Twenty-six samples of fresh and processed aquatic products from different species were determined for boron content by inductively coupled plasma mass spectrometry. Boron content in Antarctic krill, Ark shell, oyster and Ruditapes philippinarum (1.183–4.240 mg/kg) were much higher than other samples, while turbot had the lowest boron content (0.006 mg/kg). In decreasing order of boron content, different living environments were wild marine, farmed freshwater and farmed marine for fish, wild marine, farmed marine and farmed freshwater for shrimp, and farmed marine and farmed freshwater for crab. Boron content in aquatic products ranged from 0.458 to 0.849 mg/kg, lower than 0.900 mg/kg. We assessed most of the tested fresh and processed aquatic products to be safe to eat. However, Antarctic krill, oyster, Ark shell and Ruditapes philippinarum should be eaten less for safety purpose due to higher boron content.
