Natural sources. Natural sources of
cobalt in the environment are soil, dust,
seawater, volcanic eruptions and forest
fires.
Industry. Cobalt is used for for the
manufacture of alloys, hard metals and
magnets.
Drinking water. A guideline value of
0.01 mg/litre was recommended for
cobalt in drinking-water.
Toxicity. As a constituent of vitamin
B12, cobalt is an essential element and,
so far, another physiological role of
cobalt has not been demonstrated in
human nutrition.
