Magnesium

formula: Mg; CAS Registry Number: 7439-95-4

Naturally occurring non-toxic alkaline earth metal

Magnesium is a widespread earth alkaline metal. Due to its high reactivity it naturally occurs only as salt and as ion. The metal and its compounds are used mainly in metal working industries, pyrotechnics and pharmaceutical industry.

For plants, animals and humans magnesium is an essential element with multiple functions. Magnesium levels are therefore strictly regulated by homeostasis in animals and humans. Its toxicity is low. More common is Mg-deficiency.

Specimen

  • Common brown alga of the coastal areas of the North and Baltic Sea
  • A major primary producer in semi-natural and anthropogenic affected ecosystems.
  • A major primary producer in semi-natural and anthropogenic affected ecosystems.
  • A deciduous tree typical of ecosystems close to dense conurbations and an indicator for the characterisation of the immission situation during the vegetation period.
  • As the most dominant deciduous tree species in Central Europe, it plays a significant role in most nearly natural and also anthropogenically influenced forest ecosystems up to an altitude of 1100 m.
  • As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
  • As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
  • Student groups with an even number of female and male students at the age of 20 to 29.
