Influence of sedimentation on enrichment of manganese and growth of ferromanganese micronodules, Bengal Fan, India
Based upon down core variations in OrMn ratio in sediment and in micronodules, Mn content, organic carbon and abundance of micronodules in two box cores from high and low sedimentation regions of the Bay of Bengal, 0–20 and 0–40 cm levels were identified as ‘‘Mn oxidation zone’’ in the western and the eastern regions of the bay. Despite similarity in bottom water O and organic carbon contents o...
متن کاملManganese induced parkinsonism: an outbreak due to an unrepaired ventilation control system in a ferromanganese smelter.
Several cases of parkinsonism were found in a ferromanganese smelter after the ventilation system had broken down and had not been repaired for eight months in 1985. To determine the aetiology and prevalence of parkinsonism, 132 workers were submitted to thorough medical examination and estimated air concentrations of carbon monoxide and manganese at different worksites. Only six of eight worke...
متن کاملManganese transport and the role of manganese in virulence.
Two areas of research have recently converged to highlight important roles for Mn(2+) in pathogenesis: the recognition that both bacterial Nramp homologs and members of LraI family of proteins are Mn(2+) transporters. Their mutation is associated with decreased virulence of various bacterial species. Thus, Mn(2+) appears to be essential for bacterial virulence. This review describes what is cur...
متن کاملA New Polarographic Method for Determining Traces of Manganese Suspended in Industrial Atmospheres
The toxic effects ofmanganese in various industries have become important from the point of view of industrial medicine. This has led us to seek a more sensitive method for determining this. toxic element in industrial environments. Industries concerned are the metallurgical and iron and steel, and also those engaged in the manufacture of glass, paint, varnish, and electric batteries; the solde...
متن کاملRecovery of Manganese and Phosphorus from Dephosphorization Slag with Wet Magnetic Separation
The dephosphorization slag has a great potential as the secondary resources of manganese and phosphorus, while quite a large amount of slag is landfilled and simply reused such as cement. The objective of this study is to investigate the recovery of manganese and phosphorus by wet magnetic separation technique. The hot metal pretreatment slag (dephosphorization slag) generally contains a Ca3P2O...
