Comparison on Contents of Trace Elements between Captive and Wild Sichuan Golden Monkeys

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.
