Conclusion on classification

Degradation:

Biodegradation: readily biodegradable: 63% after 28 d (CO2 evolution, OECD 310, 10-day window does not apply)

 

Bioaccumulation:

Log Kow = 5.97 (at 23.4 °C; EU Method A.8, HPLC method)

 

Aquatic acute toxicity:

Fish = LC50 (96 h, Danio rerio): 1.945 mg/L (meas., geom. mean)

Aquatic invertebrates = EC50 (48 h, Daphnia magna): 0.418 mg/L (meas., geom. mean)

Algae = ErC50 (72 h, Pseudokirchneriella subcapitata): 0.711 mg/L (meas., geom. mean)

 

Aquatic chronic toxicity

Fish = no data available

Aquatic invertebrates = no data available

Algae = ErC10 (72 h, Pseudokirchneriella subcapitata): 0.33 mg/L (meas., geom. mean)

 

Classification according to CLP

Acute toxicity data are available for all three trophic levels whereas chronic data are available only for algae. Aquatic invertebrates and algae exhibit a EC50 < 1 mg/L. Thus, the tested substance needs to be classified as “acute category 1” (H400) with an M factor for acute aquatic toxicity of 1, according to the 6th ATP of Regulation (EC) No 1272/2008 (CLP). Furthermore, the tested substance is considered to be rapidly degradable and has a high potential for bioaccumulation based on the log Kow (Log Kow = 5.97). Thus, the substance needs additionally to be classified as “chronic category 1” (H410) according to the 6th ATP of Regulation (EC) No 1272/2008 (CLP) based on the available acute toxicity data.
