The T-value in the score for hazard refers to acute toxicity. Underlying data for P, B, T and risk are from Fass.
Below is Hazard and Risk from Fass environmental information for Androcur (cyproterone) (downloaded 2018-11-01).
Persistence: "CO2 evolution test, guideline OECD 301B (80).Test results 0% degradation in 28 days."
Bioaccumulation OECD 117: Log Pow = 3.36.
Acute toxicity OECD 202: There are data for 1 trophic level for crustaceans (Daphnia magna) 2.4 mg/L.
Risk of environmental impact of cyproterone acetate cannot be excluded, since there is not sufficient ecotoxicity data available.
Critical effect concentration (CEC) for cyproterone is 1 786 ng/L. Log P is set to 3.6.
