Even though zinc is nontoxic to human beings, concentrations higher than 5mg/L (ppm) can cause a bitter, astringent taste. This level of zinc can result in a milky color in alkaline water and is irritant to the human digestive system. Zinc in low quantities is a beneficial and necessary element for body growth. Zinc is normally introduced into drinking water through industrial effluents. In addition to drinking water, zinc is measured in surface finishing, boilers and cooling towers, water conditioning and effluent waters. | |
