【摘要】 利用电感耦合等离子体质谱(ICP-MS)对梨形环棱螺(Bellamya purificata)青色和紫色贝壳的7种金属元素质量分数进行了比较分析。结果显示:紫色梨形环棱螺贝壳中铁(Fe)质量分数显著高于青色贝壳。青色贝壳中钾(K)、镁(Mg)、锰(Mn)的含量显著高于紫色贝壳,钠(Na)、锶(Sr)、锌(Zn)元素含量在两种壳色贝壳中差异不显著。贝壳中Fe含量和K、Mg、Mn的含量呈显著负相关,与Sr、Zn含量的相关性不显著。K、Mg、Mn、Na的4种元素含量呈显著正相关。更多还原

【Abstract】 Seven metallic elements in shell from two shells color strains(purple and cyan) of B. purificata are analyzed by ICP-MS. The results showed that the content of Fe in purple shell was higher than that in cyan shell significantly, while the contents of K, Mg, Mn in cyan shell were higher than that in purple shell. The contents of Na, Sr, Zn had no difference in these two kinds of shells. The content of Fe had negative correlations with the content of K, Mg, Mn in the two color shells and it had no obvious correlation with Sr and Zn, and there were significantly positive correlations between the contents of K, Mg, Mn and Na.更多还原
