Description of key information

Though the test substance is hydrolytically stable, it is rapidly removed from surface waters via adsorption to underlying sediment. In an aerobic mineralisation study the test substance did not mineralise and was stable in surface water during the 60-day study.  In a laboratory water/sediment study, the half-life (DT50) of the test substance in the water phase was 7.3–17.4 days. Once in the sediment the test substance is degraded with an overall whole system DT50 of 47-56.7 days. The rate of aerobic degradation of the test substance in the laboratory was measured in four different soils. Under laboratory conditions, the test substance degraded quickly with DT50 values ranged from 19.1 to 31.8 days at 20°C. No correlation was observed between the rate of degradation of the test substance and soil pH.
