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.
