The oral LD50 is 3.75, 1.5 and 2.0 g/kg in rats,
mice and rabbits respectively.
Also it was concluded that picloram is not carcinogenic.
Picloram is a systemic herbicide used for general woody plant control.
Chemical name: 4-amino-3,5,6-trichloro-2-pyridinecarboxylic acid
Chemical class/use: chlorobenzoic acid herbicide
Solubility in water: 430 mg/l (salt. 200,000 mg/l)
Solubility in other solvents: acetone 1.98 g/100 g; ethanol 1.05 g/100 g; benzene 0.02 g/100 g
Melting Point: 218-219 °C
Vapor Pressure: 6.16 x 10 to the minus 7 mm Hg at 35 °C
Picloram is a slightly toxic herbicide and therefore requires the signal word CAUTION on its label. It is of moderate toxicity to the eyes and only mildly toxic on the skin. There is no documented history of human intoxication by picloram so symptoms of acute exposure are difficult to characterize. A possible symptom from massive amounts would be nausea.
The oral LD50 for picloram is 8,200 mg/kg in rats, between 1,061-4,000 mg/kg for mice, between 1,922-3,000 mg/kg for guinea pigs, and between 2,000- 3,500 mg/kg for rabbits. The rabbit dermal LD50 is greater than 4,000 mg/kg, a level which produced no mortality or toxic signs. Inhalation by a rat of a formulated product failed to achieve an LC50 and no adverse effects were observed for two weeks following the administration of the compound.
Mice fed large quantities (1,000 to 2,000 mg/kg/day) of picloram for 13 weeks experienced no clinical or blood changes. Females did show decreased body weight and increased liver weights. Over a wide range of doses (30-1,000 mg/kg/day) for 32 days, no effects were seen in rat livers. Dogs, sheep and beef cattle fed low levels of picloram for a month experienced no toxic effects.
Ducks, pheasant, and quail had picloram related LD50 values of greater than 2,000-5,000 mg/kg, with no mortality seen at even the highest levels. This indicates that the compound is practically non-toxic to wildfowl.
Picloram is moderately to slightly toxic to fish. Rainbow trout had a picloram related 96-hour LC50 of 19.3 mg/l, while it was 6.3 mg/l for the technical material in channel catfish. The isooctylester was more toxic. The LD50 for the isooctylester in rainbow trout is 4 mg/l, and in channel catfish is 1.4 mg/l. With LC50 values ranging from 10 to 68 mg/l, picloram is only slightly toxic to aquatic invertebrates The compound is non- toxic to bees .
The U.S. Fish and Wildlife service has determined that the compound, because of its persistence, mobility and toxicity to plants, may pose a threat to endangered plant species. The EPA is developing guidelines to reduce the potential of affecting these plants.
