2009年4月中旬在大连大窑湾海域采集了750只含麻痹性贝毒的紫贻贝吊养于大连棋盘磨附近海域,使其体内麻痹性贝毒在天然海域内自净。研究结果表明:试验所用紫贻贝软体部中麻痹性贝毒以N-磺酰氨甲酰基类毒素C1/C2和膝沟藻类毒素GTX2/3为主,其中后者占总毒素的65.08%,且降解速度较快;消化腺中毒素成分复杂,毒素含量高,是紫贻贝体内麻痹性贝毒的主要富集器官,在排出过程中毒素含量变化复杂;紫贻贝闭壳肌中毒素成分以新石房蛤毒素neo-STX为主,占总毒素含量的96.59%,其在试验过程中并没有明显降低趋势,反而波动上升,实验结束时其含量增加了34.75μgSTXeq/100 g;在性腺、鳃、外套膜中没有检测到任何形式的麻痹性贝毒成分。
In mid-April 2009, 750 purple mussel mussels with paralytic shellfish poison were collected from the sea near Dalian chequerboard mill in the sea area of Dayao Bay in Dalian to self-purify their paralytic shellfish poison in the natural sea. The results showed that the paralytic shellfish poisoning in the mussel mussel used in the experiment was mainly N-sulfonylcarboxyl toxoid C1 / C2 and knee xylose toxin GTX2 / 3, of which the latter accounted for 65.08% of the total toxins, And the degradation rate is faster; the toxin component of digestive gland is complex and the toxin content is high, which is the main enrichment organ of the paralytic shellfish poisoning in the mussel body, and the toxin content changes evidently during the excretion process; The neoxanthin-STX-based neotoxin-STX accounted for 96.59% of the total toxins. However, the neotoxin-STX content did not show a significant trend of decrease during the test but instead increased. At the end of the experiment, the content increased by 34.75 μgSTXeq / 100 g. , Gills, mantle no detectable form of paralytic shellfish poisoning ingredients.
