An Environmental Study of Casting Copper-Cadmium Alloys

An environmental study to measure the concen- trations of airborne cadmium oxide was carried out at the factories referred to by Bonnell on page 181, reporting the results of the clinical investigation of men exposed to cadmium oxide fume. Bonnell found that a number of these men had symptoms of chronic cadmium poisoning. Although the working conditions in the industry have improved in recent years, it was considered that knowledge -of the present exposure to cadmium fume would be of interest both in assessing the present risk to health, and in providing information which might be of value should further cases occur.
