3.3 The correlation analysis of heavy metals The correlation coefficients of heavy metals in surface water of Linglong gold deposit areas are listed in Table 2. The results indicated that Pb-Cr, Hg-Cu, Hg-Cd, Cu-Cd had a significance correlation that the correlation coefficients were 0.960, 0.986, 0.966, 0.980 in the level of P=0.01, respectively.
