Any other information on results incl. tables
The potassium cation is ubiquitously present in the environment, occurring naturally in minerals, soils and sediments, natural waters (oceans, lakes, rivers), biota and human beings. Potassium is the seventh most abundant element on earth, constituting 2.40% by weight of the earth’s crust. It occurs in many igneous rocks, such as feldspar, mica and, other potassium aluminum silicates, and marine sediments. Marine deposits of potassium, mainly as potassium chloride associated with sodium chloride, are found in practically all salt beds. Naturally occurring disintegration of these rocks and deposits adds potassium to soil and water. It is abundantly present in sea water at a concentration of 380 mg/l. UNEP (1995) reported concentrations for a total number of 75 rivers in North America, South America, Asia, Africa, Europe and Oceania. The 10th –percentile, mean and 90th-percentile were 0.8, 3.2 and 6.0 mg/l respectively. The potassium concentration of topsoils is 0.2-3.3%. Potassium is an essential constituent in plants, animals, and humans. Potassium concentrations in dry matter of crops are in the range of 0.344 to 3.5%. The total amount of potassium in human beings is in the range of 40-50 mmol (154-1955 mg)/kg bw.
