Environmental ProfileEcotoxicology:
Bees:Non-toxic.50 480 mg/bee.Birds:Acute oral 50 for Japanese quail >10 200 / .Daphnia:Low toxicity; 50 (48 h) 233.4 /l (measured); 353.6 /l (nominal).Fish: 50 (96 h) for trout 31.3, bluegill sunfish 27 /l.
Environmental fate:
Animals:In urine, major metabolites are N-[2-chloro-6-(methylsulfinyl)phenyl]glycine and N-[N-[2-chloro-6-(methylthio)phenyl]glycinyl]aniline. There are also small amounts of other acid-labile polar conjugates of benazolin acid, andd 1.0 (sandy loam), 0.4 (loam).Plant:Benazolin acid is metabolised to form acid-labile conjugates. Minor pathways include hydroxylation of the aromatic ring of benazolin acid and loss of the acetic acid side-chain, followed by conjugation. Benazolin acid is translocated more rapidly and to a -
