Detaljerad miljöinformation

Upon release of wastewater effluents into the aquatic compartment, based on an aqueous dissipation rate (DT50) of 0.7 and 1.2 days, crizotinib is expected to rapidly dissipate from the water to the sediment with approximately 18.4% to 43.3% becoming irreversibly bound. Degradation products observed in all water and sediment extracts, ranging from <10% to 39.7% of the dose indicate that crizotinib is expected to undergo primary degradation in the water-sediment compartment. Total system half-life values were 4.6 and 37.1 days.

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) = 1.37*10-6*A(100-R)

PEC = 0.000828 μg/L


A =

6.045 kg (total sold amount API in Sweden year 2019, data from IQVIA) (Reference 3).

R =

0% removal rate (worst case scenario)

P =

number of inhabitants in Sweden = 10 * 106

V (L/day) =

wastewater volume per capita and day = 200 (ECHA default) (Reference 1)

D =

factor for waste water dilution by surface water flow = 10 (ECHA default) (Reference 1)

Predicted No Effect Concentration (PNEC)

Ecotoxicological studies

Activated sludge microorgansims (guideline OECD 209) (Reference 5)

EC15 (respiration inhibition) = 834 500 μg/L

EC50 (respiration inhibition) = > 1000 000 μg/L

Green alga (Pseudokirchneriella subcapitata) (guideline OECD 201) (Reference 6)

EC50 96 h (growth rate, chronic toxicity) = >47 μg/L

NOEC 96 h (growth rate, chronic toxicity) = 9.3 μg/L

Daphnids (Daphnia magna) (guideline OECD 211) (Reference 7)

LOEC 21 days (reproduction, chronic toxicity) = >130 μg/L

NOEC 21 days (reproduction, chronic toxicity) = 130 μg/L

Fathead Minnow (Pimephales promleas) (guideline OECD 210) (Reference 8)

LOEC 33 days (growth, chronic toxicity) = 120 μg/L

NOEC 33 days (growth, chronic toxicity) = 70 μg/L

Midge (Chironomus riparius) (guideline OECD 218) (Reference 9)

LOEC 28 days (emergence, chronic toxicity) = 234 000 μg/kg

NOEC 28 days (emergence, chronic toxicity) = 108 000 μg/kg

Based on the lowest NOEC for the species Pseudokirchneriella subcapitata and using the assessment factor (Reference 2) of 10, the PNEC is calculated to 9.3 / 10 = 0.93 µg/L.

Environmental risk classification (PEC/PNEC ratio)

PEC/PNEC = 0.000828 / 0.93 = 0.00089, i.e. PEC/PNEC ≤ 0.1 which justifies the phrase ”Use of crizotinib has been considered to result in insignificant environmental risk.”

Justification of chosen degradation phrase

The total system DT50 value (water-sediment transformation simulation, OECD 308) was calculated to up to 37.1 days in the low organic content sediment. Furthermore, at the end of the study, 29.5% of the parent substance was measured in the high organic content sediment. Therefore, the phrase ”crizotinib is slowly degraded in the environment” is chosen to describe the degradation characteristics of the substance.

Log Pow







Justification of chosen bioaccumulation phrase

Since BCF < 500 and log P is <4, ”crizotinib has low potential for bioaccumulation”.
