Description of key information
Desmedipham is considered not to be readily biodegradable as 21 % of desmedipham was degraded during 28 days in test solution inoculated with mixture of sewage plant effluent and five soils.
The half life in freshwater of 0.28 days (at 12 °C) is based on the low concentration aerobic mineralisation study (OECD 309) and the half life in freshwater sediment of 0.16 days (at 12 °C) is based on a total system value from five water/sediment studies.
The soil half life for use in chemical safety assessment is based on eight soils (and two radiolabelled forms of desmedipham) is 67.3 days at 12 °C.
All DT50 values were calculated following FOCUS guidance.
