Cadmium is a naturally occurring metal found in the earth’s crust It is always found combined with other substances such as oxygen cadmium oxide sulphur cadmium sulphate or suphide and chlorine cadmium chloride Cadmium compounds are close to its source Since it occurs naturally in the earth s crust cadmium may also enter the atmosphere from the weathering of rocks windblown soil and volcano However these sources are minor compared with anthropogenic on In the environment cadmium occurs as a divalent metal that is insoluble in water but its chloride
