水产品中重金属生物可给性与生物有效性研究进展

水产品对重金属具有富集作用,因此时常出现的重金属含量超标现象成为影响水产品质量安全的重要因素,在降低消费者信心的同时也严重影响了整个水产行业经济的健康发展.重金属对人体产生的毒副作用跟其摄入体内被吸收利用的程度相关,只有被肠道吸收的部分才会对人体产生危害.因此,为了更加科学地评估食品中重金属等有毒有害物质的危害,可通过...

Research progress of bio-accessibility and bioavailability of heavy metals in aquatic products

Aquatic products can enrich heavy metals, and the excessive content of heavy metals in aquatic products has become an unfavorable factor affecting the quality and safety of them. It not only lowered the confidence of consumer, but also seriously affected the healthy development of the aquatic industry economy. The toxic and side effects of heavy metals on human body are related to the degree of absorption and utilization of heavy metals in the body, and only the part absorbed by the intestine will be harmful. Therefore, in order to evaluate the harm of heavy metals and other toxic and harmful substances in food more scientifically, the methods of bio-accessibility and bioavailability could be studied. In this paper, several heavy metals in aquatic products, the relationship, research methods and application of bio-accessibility and bioavailability are summarized, which provided a theoretical basis for further scientific evaluation on the harm of heavy metals to human health and edible safety of aquatic products.
