摘  要：
通过微波消解-冷原子荧光光谱法检测苏州地产水生蔬菜与太湖水产品的总汞含量,并研究其分布规律。测定结果显示:螃蟹总汞含量最高,其中雄蟹蟹膏部位高达0.470mg/kg,其他水产品包括白鱼、白虾及螺蛳等总汞含量均较低;水生蔬菜除茭白外,均受到不同程度的汞污染,汞含量已超过我国限量标准,其变化呈现浮叶植物高于挺水植物、裸露植物高于有包裹植物的趋势。

摘  要：
Total mercury content in aquatic vegetables cultivated in Suzhou and aquatic products in Taihu Lake was determined by microwave digestion and cold atomic fluorescent spectrometry(AFS).The highest total mercury content was found in crab among six species of aquatic production from Taihu Lake,which was as high as 0.470 mg/kg in male crab paste.Total mercury content was relatively lower in other aquatic products such as white fish,white shrimp,Margarya,and so on.Except Zizania caduciflora,all other aquatic vegetables from Suzhou under investigation were polluted by mercury to different extent with a content exceeding the national standard limit.Total mercury content was higher in floating leaf vegetable than emerged vegetable,in naked vegetable than wrapped vegetable.
