Additional information

The substance is not readily biodegradable following the criteria given by OECD Guidelines for the Testing of Chemicals (30 % after 28d) but an aerobic soil environment will have a significant contribution to the overall degradation of the substance. The half lives in aerobic soils (DT50) of the substance were between 2.3 to 10.6 days at 20°C in the different soils. Under anaerobic conditions, cyprosulfamide degraded slower with a half life of approx. 48.5 – 59.5 days at 20°C. therefore the substance will be not persistent in the environment.
