Cobalt is a naturally occurring element in the Earth's crust (at around 20-30 parts per million (mg/kg); the 32 nd most abundant element) and as a consequence cobalt substances are naturally and ubiquitously present in the air, soil, sediments and water.. In addition, because of worldwide use, cobalt can be released into the environment as a result of man's activities.
