Description of key information

With high probability acutely not harmful to aquatic algae and cyanobacteria.

Key value for chemical safety assessment

Additional information

In a GLP, 120-hour static test with the green alga Selenastrum capricornutum, according to FIFRA Guideline Number 123 -2 (EPA), the algae toxicity of 2 -hydroxyacetophenone was investigated. Statistical re-evaluation of the endpoint cell number revealed an IC50 (120h) of >100 mg/L; the IC10 (120h) was estimated to be 36.6 mg/L, both related to nominal test concentrations.

In conclusion, the substance is with a high probability acutely not harmful to aquatic algae and cyanobacteria.
