  • (M) Water from the mines; (D) Water from the dammed lakes; (*) shown in Figs. 3 and 4.

  • (–): Too much scatter among replicates.

  • Elements never significantly exceeding 1 ppb are not shown in the table, i.e., Sc, Ga, Ge, Se, Y, Zr, Nb, Mo, Ag, Cd, Sb, Sn, REE, Yb, Lu, Hf, W, PGE, Hg, Bi, and Th.

  • Other elements such as P, Sc, Fe, Co, and Mg are not shown either. Accuracy is several % for ppb concentrations.
