Quantifying Concentration of Trace Elements,Heavy Metals in Hair of Père David's Deer and Its Application in Environmental Monitoring
Life conditions and habitat status of mammals could be reflected by trace elements and heavy metals in animal hair which is also a key biological-chemical indicator.To explore the feasibility of monitoring the habitat environment through the content of trace elements and heavy metals in hair of Père David's deer(Elaphurus davidianus),we studied 34 trace el-ements and 10 heavy metals in hair of Père David's deer from Beijing Milu Park(BMP)and Lin'an City of Zhejiang Prov-ince(LAZJ).The results showed that except Re,the other 43 elements were detected in the hair of Père David's deer.34 elements were the characteristic elements such as Li,Be,Sc,V,Co,Ga,Rb,Ir,Mo,Cd,Cs,Ba,La,Ce,Pr,Nd,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm,Yb,Lu,Tl,Bi,Th,U,Nb,Ta,Zr and Hf.Concentration of six trace elements includ-ing Sr,In,Sb,W,Bi,U and five heavy metals including Zn,Cu,Cr,Pb,Cd in hair of LAZJ were lower than those in BMP,concentration of the other 32 trace elements in LAZJ were higher than those in BMP.Independent sample t-test showed that among the 43 elements,only six elements including Cr(p=0.064),Ni(p=0.769),Mo(p=0.129),Tl(p= 0.065),Zr(p=0.138)and Hf(p=0.057)did not differ significantly between BMP and LAZJ,thereby regional difference ex-isted in hair of Père David's deer.Habitats and food resources of Père David's deer in BMP and LAZJ were not affected by Zn,Cu,Cr,Pb,Cd,V,Co,Ni,Sb and Tl heavy metals pollution.It is concluded that the content of trace elements and heavy metals in hair of Père David's deer can serve as non-invasive indicator materials for heavy metal pollution in their habitat.
