广东大亚湾和大鹏湾麻痹性贝类毒素研究

于1997－1999年在广东大亚湾和大鹏湾的主要贝类养殖区设立了4个采样点，以华贵栉孔扇贝和翡翠贻贝为对象逐月采样，以美国分析化学家协会（AOAC）推荐的小白鼠法测定其麻痹性贝类毒素（PSP）含量．1999年1－6月大亚湾东山海域的扇贝贝毒含量高于联合国粮农组织（FAO）制定的贝类安全食用标准的限定值，尤其是1月份，超过限定值近30倍．贻贝仅1月份超标．总体上贝毒含量表现为由冬春季高峰期逐月波动下降的趋势．大亚湾澳头和大鹏湾南澳的两种贝类毒素含量都不高，扇贝长期含有较低的毒素，贻贝在大部分时间内不含毒素．

Study on the paralytic poisoning in shellfish of Daya Bay and Dapeng Bay, Guangdong.

From 1997-1999, the paralytic shellfish poisoning (PSP) contents of scallop (Chlamys nobilis) and blue mussel (Perna viridis) collected monthly from four main shellfish growing zones in Daya Bay and Dapeng Bay,Guangdong were determined with the AOAC bioassay method. The toxins contents detected in the scallop samples in Dongshan maritime space of Daya Bay from January-June 1999 were higher than the FAO shellfish safety threshold; especially in January, the content exceeded nearly 30 times of the threshold, and the scallop sample exceeded the threshold in January only. The contents, overall, tend gradually to decrease monthly since the peak of winter-spring season. In Aotao of Daya Bay and Nanao of Dapeng Bay, the levels of two shellfish species were not high; the toxins contents of scallop were lower for a long period of time; and no toxin was contained in mussel.
