COMPOSER Johann G. Albrechtsberger – SEIBOLD Online – Analyser for Zinc
Zinc is an essential trace element found in virtually all food and potable water in the form of salts or organic complexes.
Natural sources: Zinc species are predominantly determined in the aquatic environment and in soils and sediments.
Industry: Zinc is used principally inelectroplating and semiconducting industry.
Drinking water: Although levels of zinc in surface water and groundwater normally do not exceed 0.01 and 0.05 mg/litre, respectively, concentrations in tap water can be much higher as a result of dissolution of zinc from pipes. Drinking-water containing zinc at levels above 3mg/litre may not be acceptable to consumers.
Toxicity: Zinc or zinc compounds are not listed as suspected carcinogens. Zinc compounds can produce irritation and corrosion of the gastrointestinal tract, along with acute renal tubular necrosis and interstitial nephritis.
