Such a strong association between these metals suggests their common sources of contamination in processed foods such as various activities involve in food processing industries.
Zinc (Zn) and water - Lenntech
Zn(s) + 2H +-> Zn 2+ (aq) + H 2 (g) This reaction releases hydrogen, which reacts with oxygen explosively. Zinc salts cause a milky turbidity in water in higher concentrations. Additionally, zinc may add an unwanted flavour to water. This occurs at concentrations of about 2 mg Zn 2+ / L. Solubility of zinc and zinc compounds

Superoxide dismutase - Wikipedia
Superoxide dismutase (SOD, EC 22.214.171.124) is an enzyme that alternately catalyzes the dismutation (or partitioning) of the superoxide (O − 2) radical into ordinary molecular oxygen (O 2) and hydrogen peroxide (H 2 O 2).Superoxide is produced as a by-product of oxygen metabolism and, if not regulated, causes many types of cell damage. Hydrogen peroxide is also damaging and is degraded by other ...
Immobilization of Zn, Cu, and Pb in contaminated soils using
May 30, 2009 · The phytoavailability of Cu and Zn was positively correlated to their water solubility (r = 0.907 and 0.825 for soybean Cu and Zn, respectively; r = 0.946 and 0.861 for lettuce Cu and Zn, respectively). Among the three metals, P amendments were effective in reducing Pb phytoavailability, compared to Cu and Zn.
