The Rules of Ferrous Metallurgy
The ways in which the sciences have been delineated and categorized throughout history provide insights into the formation, stabilization, and establishment of scientific systems of knowledge. The Dresdener school’s approach for explaining and categorizing the genesis of the engineering disciplines is still valid, but needs to be complemented by further-reaching methodological and theoretical r...
متن کاملLead Speciation in the Dusts Emitted from Non-Ferrous Metallurgy Processes
The paper presents results for the speciation analysis of lead in dusts derived from dedusting of technological gasses from metallurgical processes of non-ferrous metals with different elementary content, made in accordance with two equal sequential extractions. Analytical procedure A provided possibilities for determination of fraction of Pb(2+), metallic lead and fraction containing mainly le...

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...
