Fass environmental information
Fass environmental information for Zemplar (paricalcitol), downloaded 2019-04-24.
Hazard
Persistence: No data.
Bioaccumulation: "The result was Log Dow = 5.83 at pH 7.4 (guideline e.g. OECD 107). [...] Since log Dow > 4 at pH 7.4, paricalcitol has high potential for bioaccumulation."
Toxicity: No data.
Risk
"According to the European Medicines Agency guideline on environmental risk assessment of medicinal products (EMA/CHMP/SWP/4447/00), use of paricalcitol is unlikely to represent a risk for the environment, because the predicted environmental concentration (PEC) is below the action limit of 0.01 μg/L."
