Administrative data

Description of key information

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 601 L/kg.
