渤海江豚组织中钠,钙,锶,镁,磷,钾的研究

１９９０年，作者于辽东湾采集了１０头江豚标本，分别测定了其骨骼、皮肤、肌肉、肝脏、肺、肾、心、胃、肠、胰、脾、肾上腺及生殖腺等１３种组织中Ｃａ、Ｓｒ、Ｍｇ、Ｐ、Ｋ、Ｎａ６种元素的含量，详细分析了骨骼及其他各组织中的Ｃａ／Ｍｇ值、Ｃａ／Ｋ值、Ｃａ／Ｐ值、Ｃａ／Ｎａ值和Ｃａ／Ｓｒ×１００值。结果表明，Ｃａ、Ｓｒ、Ｍｇ、Ｐ，Ｋ在骨骼中累积率最高，钾在肌肉中具有高累积，Ｓｒ、Ｃａ在肌肉中累积率最低；Ｍｇ累积率最低的组织是生殖腺，Ｐ累积率最低的组织是肠，而Ｋ在骨骼中，Ｎａ在肌肉中的累积率均高于其他组织。分析结果还显示，Ｃａ／Ｍｇ值最高的是骨骼，最低为肌肉，Ｃａ／Ｐ值最高的是骨骼，最低的是肌肉和胰脏，Ｃａ／Ｋ值最高为骨骼，最低为脾Ｃａ／Ｓｒ×１００值最高为肺、最低为肠，而Ｋ／Ｎａ值最高为肌肉，最低为骨骼，在骨中Ｃａ／Ｐ值大约为１，类同于猫和人类。
