Lead

Zinc is an essential nutrient for the body, but can be harmful at concentrations beyond the threshold. Water containing zinc at high concentrations for example, can lead to stomach cramps, nausea and vomiting. Lead and zinc are important industrial metals and will continue to play a significant role in the future of the Nigeria's mining sector.
