Heavy Metal Contamination (Cu, Pb, Zn, Fe, and Mn) in Urban Dust …
Cu and Zn were also strongly correlated (r = 0.82), and they had a weaker correlation with Pb (Pb-Cu, r = 0.5; Pb-Zn, r = 0.35). This seems to indicate that Fe and Mn are elements that can share similar sources; in fact, they have been reported as elements of natural or mixed origin ( Dehghani et al., 2016 ), in studies of heavy metals.
