Title Health effects of ferrite and the raw materials dust
Bibliographic information 1983, Vol.21, No.1, p.1-9. 23 ref.
Abstract 42 workers manufacturing ferrite cores for television tubes and 33 controls were studied. 19 of them were exposed to a mean concentration of 9mg/m3 of a mixture of ferric, zinc, magnesium oxides and manganese carbonate, and 16 of them to 3mg/m3 spinelled (cubically crystallised) ferrite dust. X-rays showed small round opacities in 4 of 33 subjects exposed for ≥5 years. Exposed workers had significantly higher rates of coughing, respiratory disease, and hospital visits than controls.
