Key value for chemical safety assessment

Additional information

An additional study according to OECD 209 was not considered necessary since the toxicity control from the biodegradation key study did not indicate any inhibition of microbial degradation. The concentration used (12.8 mg/l) is highly above water solubility. Moreover, the substance is highly insoluble in water (< 1 mg/l). Thus, the criteria for adaption of information requirements according to Annex VIII, column 2, 9.1.3 are met and no additional study is necessary.
