Cancer Mortality Among Workers Exposed To Cadmium.
Lemen-RA; Lee-JS; Wagoner-JK; Blejer-HP
Cancer mortality among smelter workers exposed to cadmium (7440439) was investigated. The smelters selected were engaged in production of cadmium and cadmium products. Exposure to cadmium fumes ranged from 90 micrograms per cubic meter (microg/m3) in premold departments to 1105microg/m3 in the retort department. The mortality rate taken from company personnel files was below that anticipated. However, deaths from malignant neoplasms were greater than expected and mostly consisted of respiratory cancers. Cancer risk was greatest 30 years after initial employment. Prostatic cancer risk was greater than expected, peaking 20 years after initial exposure. Exposure risk was 25 percent less than what it was in 1947. There was also decreased risk of exposure to impurities generated during processing, such as arsenic (7440382). The authors recommend that, because of the increased mortality from malignancies and the abundance of cadmium in the environment, there is a need to reduce exposure to the metal and its compounds.
