Toxicity to terrestrial arthropods

Administrative data

Endpoint:

toxicity to non-target arthropods on natural substrate (NTA other than pollinators)

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

Justification for type of information:

In accordance with ECHA’s guidance on information requirements and chemical safety assessment, chapter R7c (v3.0 ; June 2017; pp. 154 -159), for soil hazard category 3 substances as is the case for DPTU (Non Readily biodegradable substance classified as toxic to aquatic life with long lasting effets), confirmatory long-term terrestrial toxicity testing must be carried out. Two studies performed on earthworms and on soil micro-organisms are available. Since PEC/PNEC < 1 with the confirmatory long-term soil toxicity testing no further toxicity testing for soil organisms need to be done.
