为了弄清珠江口海域麻痹性贝毒（paralytic shellfish poisoning，PSP）的污染状况，为监管海产品安全提供参考，本实验运用小白鼠生物检测法，对2007年12月至2009年5月在该海域的17个采样点采集的19个贝类品种共181份样品进行麻痹性贝毒测定．结果显示，珠江口海域贝类的PSP阳性检出率为20.4％，无超标，其中2009春季采自澳头和霞涌的华贵栉孔扇贝的检出值最高，为215 Mu/100 g软组织．PSP检出率呈明显季节特征，冬季最高，夏季次之，秋季最低．PSP的地理分布范围较广，珠江口、大鹏湾和大亚湾均有检出．主要染毒贝类为僧帽牡蛎（Ostrea cucullata）、栉江珧（Atrina pectinata）、华贵栉孔扇贝（Chlamys nobilis）、褶牡蛎（Ostrea plicatula）和近江牡蛎（Crassostrea rivularis）．

In order to understand the pattern of paralytic shellfish poisoning (PSP)in Pearl River es-tuary,PSP levels of 181 samples collected from 17 sampling sites in Pearl River estuary and its adjacent sea areas from December 2007 to May 2009 were determined with the AOAC mouse bioassay.The results showed that positive rate of PSP contamination of shellfish collected from Pearl River estuary and its adja-cent sea areas was up to 20.4%.The contents of PSP were generally low and under the public health safety standard of 400 Mu/100 g.The maximum content of PSP was in Chlamys nobilis collected from both XiaYong and AoTou in spring of 2009 with toxicity of 215 Mu/100 g.The positive rates of PSP showed a markedly seasonal differentiation,the rate were highest in winter and lowest in autumn.The ge-ographical distribution of PSP was widely.PSP pollution was found in all the sampling areas,including Pearl River estuary,Dapeng Bay and Daya Bay.The contaminated shellfish species included Ostrea cu-cullata,Atrina pectinata,Chlamys nobilis,Ostrea plicatula and Crassostrea rivularis.
