Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

The soil compartment is basically relevant for Si/FeSi silicate as a target compartment for ecotoxicological effects assesment. It is not rare that industrial slags are used extensively as soil construction materials. However, according to current information, Si/FeSi silicate is not used that way. The scope of the terrestrial effect assessment under the REACH regulation is restricted to soil organisms in a narrow sense, i. e. on non-vertebrate organisms living the majority of their lifetime within the soil and being exposed to substances via the soil pathway.

Exposure based adaptation rules have been given for testing requirements for terrestrial compartment under REACH Annex IX. These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely. For Si/FeSi silicate current manufacture and use categories indicate no direct exposure of the soil compartment.

Annex XI adaptation rules offer the possibility to apply a weight of evidence approach. In the estimation of hazard and risks involved in metal constituents and impurities in Si/FeSi silicate, the read across method may be utilized in the first hand (case by case approach) by applying the already existing hazard data and PNECsoilvalues applicable for these metals and other elements.
