متن کاملnon-ferrous smelter: the role of cadmium
Lung cancer mortality was examined in a cohort of 4393 men employed at a zinc-leadcadmium smelter. There was an excess oflung cancer (overall SMR = 124-5, 95% confidence interval 107-144) which was particularly evident for those employed for more than 20 years. A statistically significant trend in SMRs with increasing duration of employment was apparent. Quantitative estimates of exposure to ca...
متن کاملPulmonary fibrosis in non-ferrous foundry workers.
Much has been written about fume fever (brass caster's ague, zinc chills, zinc shakes), and lead poisoning in brass foundries has been dealt with recently by Stalker (1947) and Hamlin and Weber (1947), but the references to pulmonary fibrosis amongst non-ferrous foundry workers are few. Stalker wrote that " the incidence of advanced silicosis has been generally low among [brass] foundrymen ". M...
متن کاملControl of Non - Ferrous Electric Arc Furnaces
An important aspect of non-ferrous metal production is the separation process known as smelting, in which the concentrated ore is melted and separated into two components of different densities: the slag and the matte. The smelting process is carried out through high-power heating in electric arc furnaces. In order to maintain a constant desired matte production rate and constant matte and slag...
متن کاملHeat stress in non-ferrous foundries.
In a previous paper (Turner, 1957) the results of a survey of the thermal environments in non-ferrous foundries were reported, reference was made to the index of heat stress proposed by Belding and Hatch (1955), and an indication was given of how this index could be used to evaluate the severity of the heat stress which might be encountered in foundries. A few observations were reported which s...
