P. Negligible. Solubility, easily soluble in water, slightly soluble in short-China alcohol, practically insoluble in most other organic solvents. Stability stable in neutral and acidic media, but readily oxidized in alkaline media. Tech salts are corrosive to common metals.Toxicity: paraquat dichlorideReviews FAO/WHO 47, 49 (see part 2 of the Bibliography). Oral Acute oral LD50for rats 157-129, guinea pigs 30-58 mg/kg. Skin and eye Acute percutaneous LD50for rats 911 mg paraquat ion/kg. Irritating to skin and eyes (rabbits). Absorption through intact human skin is minimal; exposures can cause irritation and a delay in the healing of cuts and wounds; can cause temporary damage to nails. Not a skin sensitiser (guinea pigs). Inhalation No vapour toxicity. Extreme exposure to spray droplets may cause nose bleeding. NOEL (1 y) for dogs 0.65 mg/kg b.w. daily; (2 y) for rats 1.7 mg/kg b.w. daily. ADI (JMPR) 0.004 mg/kg b.w. (as paraquat ion) [1986]. Toxicity class WHO (a.i.) II; EPA (formulation) II (oral, a.i.); III (dermal, a.i.)
