The concentration of elements that exceed the guideline values
(Fe and Mn) in this study were compared to those reported by
other authors in more detail (Table 3). Similar concentrations of Fe,
were reported for Paraibuna River (Atlantic Forest, Brazil) [27], La
Plata River (Uruguay and Paraná Rivers are the main affluent of the
La Plata river) [8] and Chenab River (Pakistan) [36] (Table 3). Fe
and Mn levels were relatively low compared to other water bodies
such as the Chascomús Lagoon (Argentina) [45] and Bara River
(Pakistan) [35].
