Fate
Environmental: In soil, undergoes metabolism to the corresponding acid, with further photolytic degradation. Half-life in soil is ca. 9-13 days. Animals: In animals, following oral administration, methoxyphenone and its metabolites are rapidly excreted in the faeces and urine. No bioaccumulation.
Toxicology
Mammals: Acute oral LD50 for rats >5000, mice >4000 mg/kg. Acute percutaneous LD50 for rats >5000 mg/kg. In 90-day feeding trials, no-effect level for rats was 1500 mg/kg diet, and for mice 1000 mg/kg diet. Fish: LC50 (48 hours) for carp 3.2, goldfish 10 mg/l.
