中文摘要:

      目的 了解太湖水产品中微囊藻毒素-RR(microcystin-RR, MC-RR)的污染状况, 并对其进行初步非致癌健康风险评估。方法 采用高效液相色谱-质谱法(high performance liquid chromatography-mass spectrometry, HPLC-MS)测定太湖部分水产品中的MC-RR的含量, 参照国际环境建模和软件协会推荐的模型对其初步风险进行评价。结果 太湖部分水产品可食部分中MC-RR的非致癌年度健康风险值在0.060×10?6 a?1~0.18×10?6 a?1之间, 其中鲤鱼风险值最高, 河蚌风险值最低。结论 所采太湖水产品中MC-RR年度健康风险值均在最大可接受范围内, 但部分水产品长期食用有一定健康风险, 需引起人们注意。

英文摘要:

      Objective To study the pollution status of microcystin-RR (MC-RR) in aquatic products of Taihu lake and conduct the non-carcinogenic health risk assessment. Methods The contents of MC-RR in some aquatic products of Taihu lake were detected by high performance liquid chromatography-mass spectrometry (HPLC-MS), and the health risk of MC-RR was preliminarily assessed using the model of international environmental modeling and software association. Results The annual non-carcinogenic risk of MC-RR in some edible parts of aquatic products of Taihu lake were ranged from 0.060×10?6 a?1 to 0.18×10?6 a?1. The carp had the highest risk and river clam had the lowest risk on human health. Conclusion The annual non-carcinogenic risk of MC-RR in aquatic products of Taihu lake is approaching to the maximum acceptable risk level, while some aquatic products eaten regularly present certain health risks, which need to attract people's attention.
