Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Endpoint:
toxicity to terrestrial arthropods: long-term
Type of information:
experimental study
Adequacy of study:
other information
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: No data on the methodology used. The common habitat of the species (grain-feeding pest, often found feeding on flour, cereals and dry grain products in food storage areas) is not representative of the terrestrial compartment.

Applicant's summary and conclusion

Validity criteria fulfilled:
not specified
Conclusions:
In the test conditions, the test substance showed effect on development of spider species tested when exposed via the food. However considering the common habitat of the species (is a common grain-feeding pest, often found feeding on flour, cereals and dry grain products in food storage areas) these results cannot be used to establish a classification on its own, it can only support other data in the terrestrial compartment.
