Occurrence and probabilistic health risk assessment (PRA) of dissolved metals in surface water sources in Southern Peru

The potential sources of transition metal contamination were deduced by applying the multivariant statistical technique, principal component analysis (PCA), to the extensive sample dataset that included 35 variables and a total of 7,686 data of metal, metalloids, and other constituent concentrations, as well as physicochemical parameters.
