摘要
测定了秦岭人工饲养 ( 10只 )和野生 ( 14只 )川金丝猴体毛中的 10种微量元素含量。锌、铁、铜、钙、镁 5种元素采用火焰原子吸收法 ;锰、铬、铅采用石墨炉原子吸收法 ;铝采用等离子光谱 ;硒经硝解后采用原子吸收法测定。结果表明 ,铬、锰、镁、铅、锌和硒的含量 ,人工猴极显著或显著高于野生猴 ;铁含量 ,人工猴极显著低于野生猴 ;钙、铜和铝的含量 ,人工猴与野生猴无显著差异。以人类毛发 10种微量元素的正常范围为参照 ,人工猴铅、铬、锰与锌 4种含量均显著超出正常范围的上限 ,属于严重超量。这可能与金丝猴饲养过程中添加营养制剂有关。
Ten trace elements including Zn,Fe,Ca,Cu,Mg,Al,Se,Mn,Cr and Pb were determined in hair of 24 Sichuan golden monkeys ( Rhinopithecus roxellanae ).The Zn,Fe,Cu,Ca,and Mg were determined by FAAS,Mn,Cr,Pb were determined by GFAAS,Al by ICP and Se by AAS respectively.The contents of trace elements in hair of 14 wild and 10 captive Sichuan golden monkeys were compared.The results showed that the contents of Cr,Mn,Mg,Pb,Zn and Se in captive monkeys were significantly higher,and that of Fe was much lower than those of wild monkeys.In addition,the contents of Pb,Cr,Mn and Zn in captive monkeys were distinctly higher than those of normal humans upper limit.This is probably because the food they eat have too much trace element additive in the captive troop.
