Aquatic short-term toxicity


Two short term toxicity studies on fish and daphnids as well as the study on algal growth inhibition are available. No acute adverse effects to any of the test organisms was observed up to the range of the water solubility level of 0.03 mg/L (5 µm filtered test solution prepared at a nominal loading of 100 mg/L). No toxic effects on each of the three species were being observed.


 


Aquatic long-term toxicity


Long-term toxicity to aquatic invertebrates


The test item Butyl methoxydibenzoyl methane had no toxic effects on survival, growth and reproduction of Daphnia magna after the exposure period of 21 days at the mean measured concentration of 3.0 μg/L, corresponding to the highest concentration of test item that could be reached in test water. Thus, the 21-day NOEC of the test item was determined to be 3.0 μg/L (mean measured), representing the water solubility limit of the test item. The 21-day LOEC and the 21-day EC10 values for the different endpoints were > 3.0 μg/L.


 


Long-term toxicity to fish


In a Fish Early Life Stage Test with Danio rerio according to OECD TG 210 at the limit concentration of 4.0 µg/L (arithm. mean measured, corresponding to solubility limit of test item in test medium), the overall NOEC of the test item was determined to be equal to or above 4.0 μg/L (arithm. mean measured), as no adverse effects were observed on hatching, survival and growth of the fish. The LOECs and EC10 values for the different endpoints were > 4.0 μg/L (arithm. mean measured). In conclusion, the test item had no toxic effects on early life stages of Danio rerio over the exposure period of 34 days at the applied limit concentration, which corresponds to the solubility limit of the test item in the test medium.
