Comparison of microwave assisted acid digestion methods for ICP-MS determination of total arsenic in fish tissue

Fish is one of the most important sources of arsenic exposure in human diet and the Food Safety and Quality Division, Ministry of Health since 2007 has required routine monitoring of total arsenic in seafoods such as fish. This study describes an improved extraction method of total arsenic in fish u...
