| 摘要: |
| 在浙江近岸海域采集了青蛤(Cyclina sinensis)、毛蚶(Scapharca subcrenata)、厚壳贻贝(Mytiluscoruscus)、缢蛏(Sinonovacula constricta)、泥螺(Bullacta exarata)、菲律宾蛤仔(Ruditapes philippinarum)、文蛤(Meretrix meretrix)、僧帽牡蛎(Ostrea cucullata)和栉孔扇贝(Chlamys farreri)共9 种贝类计29 份样品, 检测其中重金属汞、砷、铜、铅、锌、镉以及麻痹性贝毒和腹泻性贝毒。结果表明, 瑞安毛蚶、瑞安栉孔扇贝中有麻痹性贝类毒素检出, 嵊泗文蛤、毛蚶和乐清牡蛎中存在重金属超标的情况;牡蛎对汞、铜、锌、镉有较强的富集能力。 |

| Abstract: |
| Twenty nine samples belonging to 9 species of shellfishes including Cyclina sinensis, Scapharca subcrenat, Mytilus coruscus, Sinonovacula constricta, Bullacta exarata, Ruditapes philippinarum, Meretrix meretrix, Ostrea cucullata and Chlamys farreri were collected from coastal waters of Zhejiang. Heavy metals including mercury, arsenic, copper, lead, zinc, cadmium and paralytic shellfish poisoning toxins, diarrhetic shellfish poisoning toxins were detected. Paralytic shellfish poisoning toxins were detected in RuiAn S. subcrenata and Ruian C. farreri. Content of heavy metals in ShengSi M. meretrix, ShengSi S. subcrenata and LeQing O. cucullata exceed the standard, and oysters have high capability in enrichment of heavy metals such as mercury, copper, zinc and cadmium. |
