Propylidynetrimethyl trimethacrylate

Toxicity to soil macroorganisms except arthropods

Administrative data

Endpoint:

toxicity to soil macroorganisms except arthropods: long-term

Type of information:

experimental study planned

Justification for type of information:

According to the Guidance on Information Requirements and Chemical Safety Assessment, Chapter R.7c, substances should be assigned to soil hazard category 3 in case there are no indications that the substance is very toxic to aquatic organisms, and that the substance is not readily biodegradable (unless a soil DT50 < 180 days has been estimated). As the test substance fits this description, it is assigned to soil hazard category 3. Therefore, the approach for screening assessment of the terrestrial hazard in this soil category is to evaluate the risk based on EPM and to conduct a confirmatory long-term soil toxicity study.

The registrants submit a testing proposal to conduct a long-term toxicity to earthworms study (OECD 222). This long-term toxicity study will be used as relevant data to assess the potential risks of the registered substance to soil organisms.
