The T-value in the score for hazard refers to chronic toxicity. Underlying data for P, B, T and risk comes from Fass.se.
Rosuvastatin has been detected in treated wastewater in Stockholm County in the last five years (2012–2016).
Fass environmental information for Crestor (rosuvastatin) (downloaded 2018-07-04).
Persistence: OECD 308: For example "Degradation Half-life from Aqueous Layer (sediment from Brandywine creek) DT50 = 10.5 d." Conlusion: "Rosuvastatin is degraded in the environment."
Bioaccumulation: "Since Log P < 4 at pH 7, the substance has been assigned the phrase: “Rosuvastatin has low potential for bioaccumulation.”
Chronic toxicity: There is NOEC for 3 trophic levels, lowest NOEC for crustacean (Daphnia magna) 18 microg/L.
PEC/PNEC is based on sales data in Sweden in year 2014. PEC/PNEC = 0,017 which gives the risk insignificant.
