Environmental Risk Classification

Predicted Environmental Concentration (PEC)

PEC is calculated according to the following formula:

PEC (μg/L) = (A*109*(100-R))/(365*P*V*D*100) = 1.5*10-6*A(100-R)

PEC = 0.025 μg/L


A = 168 kg (total sold amount API in Sweden year 2018, data from IQVIA) (Ref. I)

R = 0 % removal rate (worst case assumption)

P = number of inhabitants in Sweden = 9 *106

V (L/day) = volume of wastewater per capita and day = 200 (ECHA default) (Ref. II)

D = factor for dilution of waste water by surface water flow = 10 (ECHA default) (Ref. II)

Predicted No Effect Concentration (PNEC)

Ecotoxicological studies

Green Algae (Selenastrum capricornutum) (OECD 201) (Ref. III)

EC50 72 h (density) >0.3 mg/L

EC50 72 h (growth rate) >0.3 mg/L

NOEC 72 h (growth rate) = 0.3 mg/L

Non-toxic up to highest concentration tested

Crustacean, water flea (Daphnia magna):

Acute toxicity

LC50 48 h (mortality) > 4 mg/L (OECD 202) (Ref. IV)

Non-toxic up to highest concentration tested

Chronic toxicity

NOEC 21 day (mortality; reproduction) = 0.3 mg/L (OECD 211) (Ref. V)

Non-toxic up to highest concentration tested

Fish, fathead minnow (Pimephales promelas):

Acute toxicity

LC50 96 h (mortality) > 0.13 mg/L (OECD 203) (Ref.VI)

Non-toxic up to highest concentration tested

Chronic toxicity

NOEC 33 days (growth, total length) = 0.05 mg/L (OECD 210) (Ref. VII)

PNEC = 0.005 mg/L = 5 µg/L (0.05 mg/L / 10) based on the most sensitive chronic NOEC for the fathead minnow and an assessment factor (AF) of 10)

Environmental risk classification (PEC/PNEC ratio)

PEC/PNEC = 0.025/5 = 0.005, i.e. PEC/PNEC ≤ 0.1 which justifies the phrase “Use of ezetimibe has been considered to result in insignificant environmental risk.”


Biotic degradation

Biodegradation Simulation Screening (OECD 301B) (Ref. VIII)

Test results 7% biodegradation to CO2 by Day 28.

Biodegradation in Sludge (OECD 314) (Ref. IX)

Test results 4% biodegradation to CO2 by Day 28

83% biodegradation to metabolites

Sediment Transformation (OECD 308) (Ref. X)

DT50 (total system) = 11 - 23 days

Two sediments and their associated waters were utilized in the study. Test systems

were dosed with 14C-labeled Ezetimibe at a nominal concentration of 0.55 mg/L in the water layer. Test systems were incubated in the dark at approximately 20 ºC for up to 103 days, and maintained under aerobic conditions by gently bubbling air into the water layers. Effluent gasses were passed through charcoal sorbent tubes to trap organic volatiles, followed by alkali solutions to trap evolved carbon dioxide. Duplicate test chambers of each sediment-water type were sacrificed on days 0, 5, 14, 28, 56 and 103. Water layers, sediment extracts and sediment solids were analyzed separately for total radioactivity by liquid scintillation counting (LSC). In addition, water layer samples were collected on days 1 and 2.

Ezetimibe demonstrated some transformation in aerobic Brandywine Creek and Choptank River test systems. The disappearance times of 50 percent of parent (DT50) from the water layers were 4.3 and 4.1 days, respectively. The DT90 values were 19.0 and 17.6 days, respectively. The amounts of Ezetimibe in the sediment layers increased to a maximum of 43% on day 14 in Brandywine Creek samples and 20% on day 28 in Choptank River samples. The amounts of Ezetimibe in the total test systems (i.e. water layers plus sediment extracts) at the end of the test were 19% and 8%, respectively. The DT50 values for parent in the total test systems were 23.1 and 11.0 days, and the DT90 values were >103 and 47.0 days, respectively. Through all test intervals, the maximum percentages of dosed radioactivity recovered as transformation products were 58% and 73%, respectively. The fractions of radiolabeled residues that could not be extracted from the sediment layers at the end of the test were 27% and 32%. The maximum amounts of mineralization or ultimate biodegradation observed were <6% for both test systems. Total mean recoveries expressed as percentages of dosed radioactivity ranged from 91% to 103% throughout the study.

Abiotic degradation

Hydrolysis (OECD 111) (Ref. XI)

Half-life of 4.5 days at pH 7

Justification of chosen degradation phrase:

Ezetimibe is inherently degradable in biological systems and via hydrolysis. The DT50 for the total system is < 32 days with > 15% parent compound remaining at the end of the study therefore the phrase, “Ezetimibe is slowly degraded in the environment” is thus chosen.


Bioconcentration Factor (BCF) (OECD 305). (Ref.XII)

Measured BCF values were 69 (low concentration) and 137 (high concentration) in a 97 day study with bluegill sunfish

Justification of chosen bioaccumulation phrase:

Since BCF < 500, the substance has low potential for bioaccumulation.
