The acute toxicity of picloram, picloram potassium salt, and picloram triisopropanolamine salt to aquatic organisms

Environmental Toxicology and Chemistry, 1984
Abstract The toxicity of technical picloram acid (93.8% active ingredient), picloram potassium salt (43.5% active ingredient) and picloram triisopropanolamine salt (65.2% active ingredient) to aquatic organisms was evaluated in static acute toxicity tests.

Pharmacokinetics of picloram in male volunteers

Toxicology and Applied Pharmacology, 1984
The fate of picloram (4-amino-3,5,6-trichloropicolinic acid), an active ingredient in TORDON brand herbicides, was defined in 6 healthy male volunteers following single po doses of 5.0 and 0.5 mg/kg, and a dermal dose of 2.0 mg/kg. Picloram was administered orally as the sodium salt in grape juice.

Carcinogenicity of picloram

Journal of Toxicology and Environmental Health, 1981
Two studies of the carcinogenicity of the herbicide picloram in animals were reviewed. Examination of histological sections showed that picloram is highly carcinogenic in rats and mice. Neoplasms at all sites, including malignant neoplasms, were increased in male and female rats given both low and high doses of picloram in the National Cancer Institute

Photochemical Degradation of Picloram

Pesticide Science, 1982
AbstractThe rate of photochemical degradation of aqueous solutions of picloram under ultraviolet light was measured by five different methods of analysis. These were chosen to assay the loss of picloram, dechlorination, alteration or loss of the aromatic amino group, loss of aromaticity, and decarboxylation.

Picloram Sorption by Soils

Soil Science Society of America Journal, 1974
Abstract Picloram (4‐amino‐3,5,6‐trichloropicolinic acid) adsorption‐desorption isotherms were derermined on six western USA soils. Adsorption isotherms were determined as a function of temperature, soil/solution ratio, and solution ionic strength.

Subcellular Distribution of Picloram

Physiologia Plantarum, 1973
AbstractGas chromatographic and radioisotopic analyses were made of cell wall, chloroplast, mitochondria and the remaining cytoplasm fractions of cowpea (Vigna sinensis Endl. cv. Southern Blackeye) trifoliates acropetal to primary leaves treated with the growth regulator 4‐amino‐3,5,6‐trichloro‐picolinic acid (picloram).

THE PHOTOLYTIC DEGRADATION OF PICLORAM

Weed Research, 1968
Summary. The effects of sunlight and ultraviolet light (253.7 nm) on 4‐amino‐3,5,6‐trichloropicolinic acid (picloram) in a basic aqueous solution were investigated. Electron‐capture gas chromatography determinations showed that approximately 20% of a 2 × 10−2 M concentration of picloram was degraded for each 48‐hr exposure to ultraviolet light of an ...

PHOTOLYSIS OF PICLORAM IN DILUTE AQUEOUS SOLUTION

Environmental Toxicology and Chemistry, 1989
Abstract The photolysis of [2,6-14C]pyridine-labeled picloram (4-amino-3,5,6-trichloro-2-pyridine carboxylic acid) was studied at 25°C in sterile, buffered water at pH 7 and in a natural water sample taken from a forest ecosystem. The first-order half-life for picloram photodegradation was the same in both systems, averaging 2.6 d at 25 ...

Dietary toxicity of picloram herbicide in rats

Journal of Toxicology and Environmental Health, 1987
The toxicity of orally administered technical-grade picloram was evaluated in male and female Fischer 344 rats. Dietary dose levels were up to 2000 mg/kg body weight (bw) X d for 2 wk, 500 mg/kg bw X d for 13 wk, or 200 mg/kg bw X d for 12 mo. Routine indices of toxicity were evaluated at all of the respective time periods.
