Ecotoxicology:
Bees:Very toxic to honeybees but, because surface residues rapidly decline, little effect seen in practice.Birds:Toxic to birds. Acute oral
LD
50 1.2-12.5
mg/kg. Not neurotoxic to hens.Fish:
LC
50 (24 h) for mosquito fish 200, harlequin fish >1000
mg/l.
Environmental fate:
Animals:In rats and dogs, following oral administration, complete metabolism and elimination occur within a few days.Soil:The dimethylamino group is converted to an
N-oxide and subsequently to -CH
2OH and -
CHO groups, followed by demethylation and hydrolysis. See K. I. Beynon
et al., Residue Rev., 1973.
WATER SOLUBILITY: Miscible.
