Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
toxicity to terrestrial plants
Type of information:
migrated information: read-across from supporting substance (structural analogue or surrogate)
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: see 'Remark'
Remarks:
The structure of iron ore pellets consists essentially of iron oxide grains. The bonding of the grains occur by oxide bridging, recrystallisation of hematite and to a lesser extent by the formation of fused silicate phases. Since silicates are inert and no effect on the environment is expected, the endpoints in Chapters 5 and 6 are based on the effects of iron as a worst case in these substances. More information on the justification of read across can be found in the attached document in the endpoint summaries of section 5 and 6.

Applicant's summary and conclusion

Conclusions:
Iron is amongst the most common elements in the earth’s crust and can be found in great abundance in both the terrestrial as sediment environment. The relative contributions of anthropogenic iron to the existing natural pools of iron in soils and sediments is therefore not relevant either in terms
of added amounts and in terms of toxicity. Based on these exposure considerations additional sediment and/or soil testing is not warranted.
