Soils contaminated with zinc from mining, refining, or fertilizing with zinc-bearing sludge can contain several grams of zinc per kilogram of dry soil. Levels of zinc in excess of 500 ppm in soil interfere with the ability of plants to absorb other essential metals, such as iron and manganese. Zinc levels of 2000 ppm to 180,000 ppm (18%) have been recorded in some soil samples. The European Soil Observatory has published the first high resolution spatial assessment of topsoil Zinc (Zn) concentrations in Europe. The mean concentration of Zn in topsoils is 47 mg/kg while 1% of the measured 22,000 samples had concentrations higher than 167 mg/kg.
