Description of key information

An OECD 211 chronic study with Daphnia magna is available.

Key value for chemical safety assessment

EC10, LC10 or NOEC for freshwater invertebrates:
0.063 mg/L

Additional information

A 21 -day OECD 211 study was performed with the mixed isomers (m and p) of diisopropylbenzene using Daphnia magna performed under semi-static conditions. The test solutions were prepared using a solvent carrier at nominal concentrations between 0.012 and 0.600 mg/L. The study resulted in a NOEC of 0.063 mg/L and a LOEC of 0.168 mg/L based upon reproduction and the time weighted mean measurements of the test solutions. The 21 -day LC50 for mortality of the parental organisms was 0.220 mg/L. These results suggest a lack of chronic or acute toxicity at the limit of water solubility.
