Título Manganese exposure in foundry furnacemen and scrap recycling workers
Información bibliográfica Nov. 1999, Vol.72, No.8, p.546-550. Illus. 20 ref.
Resumen The aim of the study was to investigate the sources and levels of manganese exposure in foundry furnacemen by a combined measuring of blood-manganese (B-Mn) and manganese in ambient air (air-Mn). Air-Mn and B-Mn were measured during and after exposure in 24 furnacemen employed in foundries and in 21 workers from a scrap recycling plant. Furnacemen who work in insufficiently ventilated smelting departments inhale, absorb and retain significant amounts of manganese in their blood despite a generally low measured airborne level of manganese fumes. The exposure values compared with post-exposure values revealed a significant decrease in the B-Mn level of the most exposed furnacemen. Two persons were suspected of suffering clinically subacute manganese intoxication as both had B-Mn levels beyond the normal limit. The results indicate that B-Mn may be a valuable parameter for estimating recent exposure (within 1-2 weeks).
