Title Production of silicon metal and alloys is associated with accelerated decline in lung function
Bibliographic information Sep. 2007, Vol.49, No.9, p.1020-1026. 27 ref.
Abstract To investigate the association between decline in lung function and the production of alloys in the Norwegian smelting industry, all 3924 employees of the sector were examined annually for five years. The outcome variable was one-second forced expiratory volume in litres divided by the square of subjects' height in metres (FEV1/height2). In the sub-cohorts of the ferrosilicon/silicon metal and silicon carbide industries, the differences between oven operators and non-exposed workers were -2.3 (-4.3 to -0.3) and -5.6 (-10.4 to -0.7) mL/(m2) x year), respectively. Implications of these findings are discussed.
