| Abstract |
In a cohort of 14,730 men employed in 12 Norwegian ferroalloy plants, overall mortality from nonmalignant respiratory diseases was not increased, but mortality from bronchitis, emphysema and asthma combined was significantly increased among men with at least three years of ferrosilicon/silicon-metal (FeSi/Si-met) furnace work. This increased mortality may be associated with previous exposure to amorphous silica. Six men died of pneumonia while still employed in a ferromanganese/siliconmanganess plant. These deaths may be associated with manganese exposure. No corresponding deaths occurred among employees in FeSi/Si-met plants. Two deaths from pneumoconiosis were observed in the total cohort. Topics: asthma; bronchitis; ferromanganese; manganese; silica; cohort study; emphysema; ferroalloys; long-term exposure; mortality; Norway; ore reduction; pneumoconiosis; pneumonia; reduction furnaces; respiratory diseases. |
