摘　　要：于2007年11月至2008年10月在深圳罗湖水产批发市场定期采集来自我国黄海海域的主要市售贝类,运用小白鼠生物法进行麻痹性贝类毒素污染状况调查。检测结果表明,产自辽宁沿海的虾夷扇贝PSP污染水平较高,检出率高达90.48%,超标率达47.62%,PSP最高值为23.84 Mu/g,超过我国食用安全标准近6倍。在时间分布上,该海域的虾夷扇贝全年都含有毒素,但冬季毒素含量水平较低,而春季毒素含量最高,夏秋季逐步下降。产自江苏连云港海域的胖江珧未检出PSP,山东蓬莱海域的栉江珧受PSP污染水平也较低,检出率仅为5.26%,无超标。The paralytic shellfish poisoning（PSP） in shellfish cultured inYellow Sea of China was investigated by the mouse bioassay.The samples were collected from Luohu seafood wholesale markets in Shenzhen during November 2007 to October 2008.The results show that Patinopecten yessoensis cultured in the coast of Liaoning province had the highest level of PSP with the positive rate of 90.48% and the over standard rate of 47.62%.The highest content of PSP was up to 23.84 Mu/g.As to the seasonal pattern,PSP was detected in P.yessoensis all the year round,samples collected in winter had a lower level of PSP and in spring had the highest level,however,the level of PSP gradually declined in summer and autumn.PSP was not detected in Pinna inflata cultured in the coast of Lian Yungang.Atrina pectinata cultured in the coast of Penglai in Shandong Province was slightly contaminated with the positive rate of 5.26%,none was over standard.
