| Abstract: |
| To study the paralytic shellfish toxins (PSTs) depuration in Japanese scallop Patinopecten yessoensis in natural environment, Japanese scallops naturally contaminated with paralytic shellfish poisoning (PSP) toxins in the Dayao Bay in the northern Huanghai Sea are transited to Qipanmo waters in the Bohai Sea of no reported PSTs incidents. The levels and profile of PSTs during 30-day depuration are detected by the high performance liquid chromatography with fluorescence detection (HPLC-FLD). The results show that the toxicity of the PSTs in soft tissues decreases to a relatively low level at Day 9. Moreover, the depurated ratio at the early stage of the PSTs depuration is higher than that at the later stage. The toxicity analysis of dissected organs reveals that the digestive gland is the most contaminated PSTs part, which is of important implication for the human health and scallop aquiculture. The mortality of Japanese scallops during PSTs depuration experiment is relevant to PSTs level in the soft tissue. |
| 中文摘要: |
| 为探究在自然环境中虾夷扇贝Patinopecten yessoensis体内麻痹性贝毒(PSTs)的净化过程,从黄海北部大窑湾海域采集了受PSTs污染的虾夷扇贝,将其转移至黄海的棋盘磨水域,该水域未曾有PSTs污染的报道。本研究采用高效液相色谱-荧光检测法(HPLC-FLD)检测30天净化过程中虾夷扇贝体内PSTs的组分和水平。研究结果发现,在第9天,虾夷扇贝软体中的PSTs的含量下降到一个相对较低的水平。而且,初期扇贝体内PSTs的净化率高于后期。扇贝各组织器官中PSTs含量分析发现,消化腺中的PSTs含量最高,这对于人类健康和扇贝养殖具有重要的意义。在本研究中还发现,虾夷扇贝的死亡率与PSTs的水平有一定的关系。 |
