| 为了弄清长江口江豚(Neophocaena asiaeorientalis sunameri)体内微量元素的积累和分布情况,本文采用电感耦合等离子体质谱仪(ICP-MS)对2014年春季收集的3头雌性和3头雄性个体的心脏、肾脏、肝脏、肌肉、肺、胃和肠等器官组织样品,作了锌(Zn)、硒(Se)、铜(Cu)、钼(Mo)、钴(Co)、铬(Cr)、锰(Mn)、钒(V)和镍(Ni)等元素含量测定。结果显示,江豚体内Zn、Cu和Se的平均含量最高,分别为59.15±33.87μg/g、15.85±15.07μg/g和7.31±5.49μg/g；Cr和Mn平均含量次之,分别为3.16±2.70μg/g和2.35±2.94μg/g；Co、Mo、Ni、V平均含量较少,分别为0.30±0.48μg/g、0.19±0.30μg/g、0.12±0.18μg/g和0.04±0.12μg/g。研究发现,肠道、肝脏和肾脏的微量元素含量普遍高于其他组织器官,除Cr以外的其他元素在一些组织中均存在显著性差异(p<0.05)。同时发现,个别元素的平均含量在雌雄性别间也存在一定差异,其中Mn雄性显著大于雌性(p<0.05),Cr则雌性显著大于雄性(p<0.01)。此外,这些元素在同一组织器官的不同个体间也并不稳定,个体间的平均变异系数达121.08%。 |
| 英文摘要: |
| The concentration of some trace elements, such as zinc(Zn), selenium(Se), copper(Cu), molybdenum(Mo), cobalt(Co), chromium(Cr), manganese(Mn), vanadium(V) and nickel(Ni),in various tissue (e.g. heart, kidney, liver, muscle, lung, stomach and intestine) of three female finless porpoise and three male finless porpoise(Neophocaena asiaeorientalis)in Yangtze River Estuary were measured by inductively coupled plasma mass spectrometer (ICP-MS). The result shows that, many trace elements were detected in various tissue or organs except V. The average content of Zn、Cu and Se were most higher than other elements(59.15±33.87、15.85±15.07 and 7.31±5.49μg/g) , the average content of Cr and Mn were take in second place(3.16±2.70 and 2.35±2.94μg/g) , the average content of Co、Mo、Ni and V were in the last one (0.30±0.48、0.19±0.30、0.12±0.18 and 0.04±0.12μg/g). Overall, the trace elements content in the intestine、liver and kidney of finless porpoise is generally higher than other tissues. The concentration of each elements in some different tissue has a significant difference (p<0.05) except chromium(Cr)(p>0.05). The results also shows that some trace element content in different gender of finless porpoise has a certain difference, like the average content of Mn in male is significantly higher than female(p<0.05) and the average content of Cr in female is significantly higher than male(p<0.01).In addition, these elements are not stable in the same tissues of different individuals of finless porpoise. On average, the variation coefficient of trace elements in different individuals was 121.08%. |
