Abstract:

China is a major producer and consumer of aquatic products.However,in recent years,due to the accumulation of heavy metals in animals and the subsequent adverse impact on human health through the food chain, excessive concentration of heavy metals in aquatic products has become a significant bottleneck for the development of the aquatic economy in China. This paper provided a concise overview of various pretreatment methods of aquatic products such as water bath heating digestion, microwave digestion, ashing digestion and electric hot plate wet digestion. The study focuses on the progress, effectiveness, advantages and limitations of these pretreatment methods in detecting heavy metal content in aquatic products. It is expected that the results of this study will serve as a valuable reference for the production and quality supervision of aquatic products.
