Heavy metal biomagnification and genotoxic damage in two trophic levels exposed to mine tailings: a network theory approach

Table 3 Centrality measures of the nodes corresponding to the network established by the relationship between sites (tailing 1, tailing 2), species (Vachellia farnesiana, Eisenia fetida), heavy metals (mg / kg), and DNA damage [μm]
