| 摘要: |
| 在浙南海域共采集了10 种贝类40 份样品。运用高效液相色谱方法检测腹泻性贝毒, 共检出9份样品含有腹泻性贝毒。染毒样品检出的腹泻性贝毒(软海绵酸, OA)质量比为0.07～5.85 μg/g, 共有7个样品含量超标, 超标率为17.5%。无论是检出率还是超标率, 都呈现夏季＞春季＞秋季的规律。浙南海域的南部腹泻性贝毒检出率和超标率比北部和中部都高。紫贻贝、缢蛏、泥蚶和青蛤较其他种类易富集腹泻性贝毒。养殖的贝类检出率及超标率均高于野生的贝类。 |

| Analysis of diarrhetic shellfish poisoning toxins in shellfishes collected from the coastal waters of south Zhejiang |

| Abstract: |
| Forty samples belonging to 10 species of shellfishes were collected in coastal waters of south Zhejiang. Diarrhetic shellfish poisoning (DSP) toxins were detected in 9 samples with high performance liquid chromatography (HPLC). The contents of DSP were between 0.07 to 5.87 μg/g; 7 samples (17.5%) exceeded the safety threshold. The positive rate and over-standard rate of DSP were mainly presented in Summer and the south. Mytilus edulis, Sinnovacula constricta, Tegillarca granosa and Cyclina sinensis showed high contents of DSP toxins. Moreover cultured shellfishes had stronger ability to accumulate DSP than wild shellfishes. |
