M.p. **5.8. B.p. **5.0. V.p. 3.*5×***2 mPa (*5). Density 1.*3 (*2). In water *3mg/L(pH 7, *2). In ethyl acetate *4, acetone *1, dichloromethane *8, ethanol *5, toluene 4.0 (all in g/L, *5). Relatively stable in neutral, weakly acidic and weakly alkaline media. Rapidly hydrolysed to the hydroxy derivative in strong acid and alkalis, and at *0 in neutral media. Toxicity: Acute oral LD*0 for rats ********0 mg/kg, mice > ********2 mg/kg. Acute percutaneous LD*0 for rats > ***0 mg/kg. Mild skin irritant; non-irritating to eyes (rabbits). Skin sensitiser in guinea pigs, but not in humans. Inhalation LC*0 (4 h) for rats > 5.8 mg/L. Ecotoxicology: Acute oral LD*0 varies from **0 mg/kg for bobwhite quail to > ***0 mg/kg for mallard ducks and ***7 mg/kg for adult Japanese quail. Dietary LC*0 (8 d) for Japanese quail > ***0 mg/kg. LC*0 (*6 h) for rainbow trout 4.***1.0, bluegill sunfish *6, carp *6, mg/L. Daphnia LC*0 (*8 h) 6.9 mg/L. Algea EC*0 (*2 h) 0.**3 mg/L. Bees LD*0 (oral) > *7 ug/bee, (contact) > ?g/bee. Environmental fate: In animals, following oral administration, atrazine is rapidly and completely metabolised, primarily by oxidative dealkylation of amino group, and by reaction of the chlorine atom with endogenous thiols.Diaminochlorotriazine is the main primary metabolite, which readily conjugates with glutathione. More than *0% of the dose is eliminated in the urine and around *3% in the faeces within *4h. In tolerant plants, atrazine is readily metabolised to hydroxyatrazine and amino acid conjugates, with further decomposition of hydroxyatrazine by degradation of the side-chains and hydrolysis of the resulting amino acids on the ring., together with evolution of CO­2. In sensitive plants, unaltered atrazine accumulates, leading to chlorosis and death. Major metabolites under all conditions are desethylatrazine and hydroxyatrazine. Mode of action: Selective systemic herbicide, abdorbed principally through the roots, but also through the foliage, with translocation acropetally in the xylem and accumulation in the apical merstems and leaves.
