【摘要】 近年来，有害藻华在中国沿海水域频繁发生。在有害藻华产生的藻毒素中，麻痹性贝类毒素(Paralytic shellfish toxins, PST)分布最广、危害最大，因而受到广泛关注。在被海洋生物摄食后，PST经食物链逐级向上传递、累积，这不仅影响生态环境安全，也威胁人类生命健康。因此，本文重点介绍了PST的定义、来源分布、危害、毒性机制、富集转化和检测方法(生物法、化学法和生物化学法),以及阐述PST的研究趋势、监管建议，旨在为完善PST研究资料、检测及防控措施提供参考。更多还原

【Abstract】 In recent years, harmful algal blooms have frequently occurred in coastal waters of China. Among the microcystins produced by these blooms, paralytic shellfish toxins(PST) are the most widely distributed and harmful, leading to significant concerns. When marine organisms ingest PST, they are passed up the food chain and accumulate, eventually posing a serious threat to human health, the environment, and the ecosystem.Therefore, this paper primarily introduces the definition, distribution, harm, toxicity mechanism, enrichment, and transformation of PST. It also discusses the methods used to detect PST, including biological, chemical, and biochemical approaches. The paper expounds on research trends and regulatory recommendations for PST. Its aim is to serve as a reference for the improvement of research, detection, and prevention of PST.更多还原
