Description of key information

Micro-organism toxicity data is available from a ready biodegradability study toxicity control performed with alpha-Terpinyl Acetate. The study is GLP-compliant and in accordance with OECD guideline 301F. In this study, activated sludge from a biological waste water treatment plant treating predominantly domestic sewage was exposed to 100 mg/L aniline (positive control) with and without addition of 100 mg/L the test substance. The oxygen depletion in both systems was measured and compared. The test substance is not inhibitory to micro-organisms, and therefore it is not considered toxic based on which the NOEC for micro-organism can be set to 100 mg/L.

Key value for chemical safety assessment

EC10 or NOEC for microorganisms:
100 mg/L
