Analyses of the Contents of Elements of Five Mosses and Their Substrates in Tongshankou Copper Mine, Hubei Province, China

By using atomatic absorption spectrophotometer,we analysed the contents of 7 elements(Cu,Zn,Ca,Mg,Cd,Pb,and Hg) in five mosses(Didymodon fallax,D.constrictus,Anoectongium clarum,Bryum dichotomum,Trichostomum sinochenii) and their substrates.The main results are as follows:① The contents of the seven elements in both the mosses and the substrates are much higher than those normal condition;② Didymodon fallax has stronger capacity to accumulate the element Cd.It can be as the indicator of Cd;③ Comparing with the other 4 mosses,Bryum dichotomum possesses stronger enriching function for Cu,Zn,and Pb.It might be as a reference indicator of Hg,and the same is Trichostomum sinochenii;④ Cu-Mg and Zn-Mg show significantly coefficient at 0.01 level,Cu-Zn,Zn-Pb and Mg-Pb show coefficient at 0.05 level.
