Aug 15, 2021 · Results indied that the environmental impact of the longabandoned iron ore mine was still evident with some high concentration of metals and acidic pH. Higher concentrations of Fe and Mn in water were noticeable in some areas while other trace elements (Pb, Zn, As, Cd, Cr, and Cu) were found below the recommended guideline values.
Trace Elements
Trace Elements. Iron (Fe) Iron is a key alyst in chlorophyll production, which makes the leaves green. Iron deficiency turns new leaves pale yellow or white while the veins remain green. A high soil pH prevents plants from absorbing iron. If necessary it can be applied as a soluble form of iron chelates.
