EC number: 215-252-9
CAS number: 1315-01-1
The substance is insoluble and hence, its log Kow is expected <<
3. Hence, its log Koc is expected << 3, too. For risk assessment
considerations, its Koc is set as 1 L/kg (log Koc=0), which classifies
the substance as mobile according to FAO classification. The substance
is a solid powder. Its mobility of particulate substance depends on the
size of the solid particles and hence its sedimentation
velocity/behaviour in STPs. The average volume distribution shows that
D90 is 6.22 µm, i.e. the texture of clay. D10 is 0.59 µm, i.e., the
texture of colloids. Hence, all particles of the substance will be
removed from waste water during STP processes, either by sedimentation
and/or by flocculation. They will hence not be part of effluents.
Groundwater contamination is excluded since particles will be filtered
during passage through sediment and/or soil layers. Furthermore the
substance occurs as natural mineral in the environment (Berndtit) which
makes it impossible to distinguish between artificial and natural
substance. Hence, the issue of transport and distribution in
environmental compartments surface water, groundwater, soil and sediment
is of no concern.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
