By-product of the manufacture of ferromanganese alloy containing primarily oxides of aluminum, manganese and silicon.
Data is provided on the surrogate substance manganese sulphate. Sorption
strength increases with pH. However, in several soils, residual 54Mn in
solution was below values expected for sorption, suggesting oxidation.
The Kd median result is considered to be sufficiently representative at
present to use in risk assessment.
At 3 days incubation the median Kd was 1598 L/kg. At 100 days incubation
the median Kd was 650 L/kg and at 180 days incubation the median Kd was
