麻痹性贝类毒素的安全评价与检测技术研究进展

Study Progress of Safety Assessment and Determination Technology of Paralytic Shellfish Poisoning Toxins

麻痹性贝类毒素(Paralytic Shellfish Poisoning Toxins,PSTs)是一类高效的钠通道神经毒素,其作为赤潮毒索的一种主要由海洋中的部分双鞭毛藻产生,通过食物链进入人体产生毒性效应,是目前已知的影响范围最广、毒性最强、危害最大的一类海洋生物毒素,因而格外引发了人们对于此类毒素的关注。本文对PSTs的来源、传递方式、理化性质、安全性评价、检测技术等热点问题及发展趋势做了详细的介绍与展望。

Paralytic shellfish poisoning toxins（PSTs）is a kind of efficient sodium channel neurotoxins.As a category of red tide toxins,PSTs is mainly produced by some marine dinoflagellataes and then make their way into humans through the food chain to present the toxic effects,of which people pay particular attention because of its broadest possible influence,strongest toxicity and greatest harmfulness in the marine biotoxins currently known.A review is given to the newest research on the or-igin,transmittal vectors,physicochemical property,safety evaluation,determination technology in detail,putting forward per-spectives to development tendency on monitoring this toxins.
