| 1 | 菲律宾蛤仔中铅、镉、汞、无机砷的含量分析及食用安全性评价显示文摘采用原子吸收光谱法和原子荧光光谱法分别对舟山本岛范围内农贸菜场和超市的菲律宾蛤仔中铅、镉、总汞、无机砷含量进行测定,并对其污染状况和食用安全性进行评价。结果显示:菲律宾蛤仔可食部分中铅、镉和总汞均符合GB 2762—2012《食品中污染物限量》要求,部分样品中无机砷含量超标,超标率在6%~10%之间,无机砷污染指数为0.71;菲律宾蛤仔中铅、镉、汞、无机砷含量小于世界卫生组织/联合国粮农组织制定的每周可耐受摄入量比例的10%。故舟山农贸菜场和超市中菲律宾蛤仔相对安全。 | 罗海军 吴益春 宋洪强 徐志进 李亭洁 祝世军 杨会成 郝云彬 | 2015 | 食品科学2015，36，4： | 6 |
| 2 | Determination and Evaluation of Heavy Metal Content of Freshwater Economic Fish in Northeast Guangdong显示文摘Concentrations of lead( Pb),cadmium( Cd),chromium( Cr),copper( Cu),zinc( Zn) and manganese( Mn) were measured in various organs( such as in liver and muscle) from 9 species of freshwater economic fishes which were collected from northeast area of Guangdong Province. The concentration of metals was measured by inductively coupled plasma atomic emission spectrometry( ICP- AES). Results showed that the levels of metals in hepatopancreas of the fishes were found in order of Zn > Pb > Cu > Hg > Cd,while in muscles were Zn > Cr> Pb > Mn > Cu > Cd. In general,the metals concentrations were significantly higher in liver samples than that in muscle samples. Based on the ' pollution index of single factor',the fishes,to one degree or another,were polluted by Pb,Cd,Cr,Cu and Zn,and pollution levels were mostly followed by Pb > Cd > Cr > Cu > Zn. The indexes of Pb and Cd tested in hepatopancreas of the fishes were in a majority exceeded the national safety criteria for food in China. What's more,it was found that the contents of the heavy metals in fishes did not vary with the trophic level which they belong to. In summary,the fishes were polluted by Pb,Cd,Cr,Cu and Zn to some extent,which indicated that hidden danger of heavy metals pollution was present in ecological environment or safety in fishery production in the area. | Yanmei ZHONG Qingmei ZHENG Chunyan HAN Rushu WEN Hongli ZHANG | 2015 | Asian Agricultural Research2015，7，1： | 0 |
