Description of key information

In order to assess the biodegradation of the substance, a screening test was performed according to OECD TG 301D (Closed Bottle Test) and under GLP conditions. In this study, river water was exposed to 2 mg/L of the substance for 28 days. The substance did not cause a reduction in the endogenous respiration. Furthermore, the validity criteria of the test were met. The substance was biodegraded by 68% at day 28 in the standard Closed Bottle screening test. The time window criterion should not be applied because the substance is a multi-constituent, because every constituent has its own biodegradation curves. The substance is therefore classified as readily biodegradable based on the >60% biodegradation reached at day 28.
