Ecotoxicological information

Long-term toxicity to aquatic invertebrates

Administrative data

long-term toxicity to aquatic invertebrates
Type of information:
experimental study planned
Study period:
2 years from ECHA's approval (final decision on TP)
Justification for type of information:
No study assessing the long-term toxicity to aquatic invertebrates is available for the registered substance. In accordance with the Decision of the Board of Appeal in case A-011-2018, the REACh Annex IX, Section 9.1., Column 2 does not allow omitting the need to submit information on long-term toxicity to aquatic invertebrates under Column 1. Therefore, long-term toxicity to aquatic invertebrates testing is a standard information requirement under annex IX of REACh regulation EC 1907/2006. Therefore, an OECD 211 study is proposed.
