RESUMO
The agglocoking blast-furnace processing of naturally alloyed ores gives rise higher volumes of dust and gas wastes which on air dispersal yield to higher concentrations of air pollution with dust, sulfur-containing substances, as well as compounds of carbon monoxide, phenol, and ammonia than that of magnetic iron ore, which yields a higher prevalence of comparable forms or reproductive disorders in women and higher general morbidity in children.

The working conditions for primary metallurgic processing of naturally alloyed ores differ from those for processing magnetic iron ores in high moisture, high concentrations of CO, SO2, aerosols of Si and Cr oxides. All these factors cause high incidence rates of chronic pulmonary and cardiovascular diseases in the workers. Naturally alloyed ores produce a greater pulmonary fibrogenic action than do magnetic iron ones.

Natural alloy ores contribute to specific pollution of the industrial environment in the blast-furnace department. The latter is characterized by elevated humidity and SO2, the higher incidence of blood circulatory disorders among the workers.
