Description of key information

There is data available from four aquatic studies 1) acute toxicity to zebra fish using semi-static conditions and 2) acute toxicity to Daphnia magna 3) growth rate inhibition on Pseudokirchneriella subcapitata 4) toxicity to the bacteria Pseudomonas putida.

Based on calculated concentrations the acute 96-hour LC50, NOEC and LC100 values for zebra fish were 72, ≤18 and 140 mg Capa-203/L, respectively.

The 48-hour LC50 for Daphnia magna was found to be 290 mg/L, while the NOEC was found to be 100 mg Capa 2043/L.

For the 72 -hour algal inhibition study a NOEC of 25 mg/L was calculated, along with an ErC50 of 165 mg Capa 2043/L.

The NOEC forPseudomonas putidawas considered to be equal to the maximum tested concentration of 461 mg Capa-203/L.

In the chemical safety assessment performed according to Article 14(3) in connection with Annex I section 3 (Environmental Hazard Assessment) no hazard was identified. Therefore according to REACH Annex I (5.0) exposure estimation is not necessary. Consequently, in accordance with Column 2 of REACH Annex IX, long term studies do not need to be conducted as all identified uses of the substance are assessed as safe for the environment.
