Retraction Note: Mining and urbanization affect river chemical water quality and macroinvertebrate communities in the upper Selenga River Basin, Mongolia

The authors have retracted this article after they became aware that the units of measurement for five elements (B, Sr, Mo, U, V) were erroneously given as mg/l instead of g/l in the measurements of chemical water quality.Consequently, the level of contamination by these elements was significantly overestimated.This error affects the results reported in Figure 3b and Table C1, as well as the Discussion section.
