Description of key information

Additional information

A number of studies are available concerning the biodegradation of benoxacor in the natural environment. It is clear from all the available studies undertaken in soil, water and sediment that benoxacor degrades extremely rapidly under aerobic and anaerobic conditions provided there is microbial activity (i.e. non sterile conditions).

Whilst benoxacor was shown not to be readily biodegradable under the conditions of an OECD 301F test, its degradation in natural water systems is rapid (for benoxacor degradation in a whole system, 2 to 3 days half life at 20 °C and 5 to 7 days at 9 °C).

Degradation is also rapid in soil, showing a DT50 of 2.3 days.
