Endpoint:
sediment toxicity: long-term
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
other:
Justification for type of information:
No experimental study on toxicity to sediment dwelling organisms is available. In accordance with column 2 of REACH Annex X performing of a study is not necessary. According to Guidance Document R.7b (v4.0; 2017; R.7.8.7) as trigger values for a sediment assessment a logKow >= 3 or logKoc >=3 are proposed. With a log Kow of 1.96 and logKoc of 1.56 the substance is well below. Furthermore, the substance is ready biodegradable and neither toxic to aquatic organisms nor ionic. A valid PNEC sediment can be calculated using EPM.
