Description of key information
Half-life in soil: 7 d, EPA Guideline Subdivision N 161-3: Photodegradation Studies on Soil (Spare, 1988)
Key value for chemical safety assessment
- Half-life in soil:
- 7 d
Additional information
The study investigated the photolytic degradation of the test item on Iowa sandy loam soil under natural sunlight conditions at a concentration of approximately 10 mg/kg soil (exposures were performed at 39°25’ North Latitude and 77°24' West Longitude).
The exposure time was 21 days at temperatures between 15 and 53 °C. Under these conditions the parent compound was readily degraded. Half life calculation gave a DT50-value of 6.8 days. One degradation product had a maximum concentration of 12% after 7 days of exposure. The compound was tentatively identified by co-chromatography with authentic reference compound to be CGA 201068. None of the other photo-degradation products observed had a concentration higher than 7% of the applied radioactivity at any sampling time.
The study demonstrates that photolytic degradation of benoxacor is rapid, with a calculated DT50 of around 7 days.
