PHYSICAL AND CHEMICAL PROPERTIES:
Paraquat dichloride forms colorless, hygroscopic crystals. Decomposing at 300 , v.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 dichloride
Acute oral LD50 for rats 150 mg/kg, for mice 104 mg/kg, for dogs 25-50 mg/kg, for sheep 70 mg/kg. Acute percutaneous LD50 for rabbits 236-500 mg paraquat ion/kg. Irritating to skin and eyes. 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. If inhaled, may cause nose bleeding. Other has serious delayed effects if absorbed. Fish toxicity: TLM (48 hrs.) is 62 ppm for rainbow trout, TLM (48 hrs.) is 40 ppm for carp. ADI : 0.004 mg/kg b.w.
