Description of key information

No significant decrease in test item concentration by hydrolysis in freshwater was detected over 28 days.

Additional information

A hydrolysis study was performed in which a nominal concentration of 2 mg/L test item was added to lake water and incubated in the dark at 25 ± 1°C for 28 days (2015). Flasks were covered with breathable membranes and samples were taken at 0, 1, 2, 6, 10, 15, 21, and 28 days for analysis of the test item by HPLC-DAD. There was no significant decrease in test item concentration in sterilised lake water in the dark over 28 days, indicating that hydrolysis is of minor importance for the removal of the test item in lake water. This study is considered to be reliable with restrictions (Klimisch 2) as the test design was adequate, however there are limitations in the reporting of results.
