摘要/Abstract

摘要： 用小白鼠生物检测法和高效液相色谱法对采自浙江舟山和广东深圳海域贝类的麻痹性贝毒素进行了调查和分析.结果表明,舟山海域近岸的贝类毒素检出率为14%,染毒的贝类毒素含量不高,低于小白鼠生物检测法的测定范围;深圳近岸贝类毒素检出率为30%以上,华贵栉孔扇贝是主要的染毒贝类,有1个样品毒素含量达5.1Mu·g^-1,超出安全食用标准.从深圳大亚湾华贵栉孔扇贝检测出10种麻痹性贝毒素成分,消化腺的主要毒素成分为GTX¹⁺²和GTX₅,C¹⁺²和GTX²⁺³,而剔除消化腺后其余贝组织的主要成分为neoSTX和GTX₅.贝毒素主要积累在扇贝的消化腺内,消化腺含有的毒素是贝肉组织的8倍.

Abstract: The paralytic shellfish poisoning (PSP) toxicity levels of shellfish collected from shellfish growing zones in Zhoushan areas of East China Sea and Shenzhen areas of South China Sea during January-November 2002 were determined with AOAC bioassay method. The results showed that the toxicity levels of shellfish from Zhoushan were very low,and few shellfish samples could be detected the PSPtoxicities.The same levels appeared in the shellfish from Shenzhen, but the percentage of shellfish samples contaminated PSP was up to 30%, and the scallop Chalmys nobilis was dominated in the contaminated shellfish species.Analyses on the toxic profiles of digest gland and edible tissue extraction of scallop from Shenzhen showed that a similar suite of toxins presented in the gland and edible tissues.The high potency neo STX and low potency GTX₅ had a high proportions, up to 60.8% and 11.4%,respectively in the tissue, and the high potency GTX ¹⁺² and GTX₅ were the dominant toxins, up to 38.9% and 20%,respectively in the gland. Most of the toxin were accumulated in ingested gland of scallop,and the toxic content in gland was about 8 folds more than that in the edible tissues.
