Abstract

The total arsenic and 6 arsenic species were investigated in 56 fish collagen products using ICPMS (Inductively coupled plasma-mass spectrometer) and HPLC-ICP-MS(High performance liquid chromatography- Inductively coupled plasma-mass spectrometer). The mean concentrations of total arsenic and arsenic species were 40.103±81.133 μg/kg (N.D.~586.686) and 30.070±50.378 μg/kg (N.D.~313.871), respectively. The mean concentration of inorganic arsenic was 24.610±32.706 μg/kg (N.D.~129.331), and the As(V) (Arsenate) was the most dominant. The standards and specifications of arsenic have not been established for fish collagen products. Our study presents that arsenic levels are relatively safe compared with not only previous studies but also domestic and international standards. However, in one sample, the total arsenic concentration was 586.686 μg/kg, showing the inorganic was 8.119 μg/kg, and the DMA was 305.752 μg/kg, which was high than the Canadian standard for organic arsenic. In conclusion, it is necessary to monitor arsenic levels consistently and establish standards and specifications of arsenic in fish collagen products to assure consumer safety.
