Pharmacokinetics of picloram in male volunteers
Toxicology and Applied Pharmacology, 1984The 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.

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

The pesticide picloram affects biomembrane models made with Langmuir monolayers.
Colloids and Surfaces B: Biointerfaces, 2019Cell membrane models are useful to obtain molecular-level information on the interaction of biologically-relevant molecules such as pesticides whose activity is believed to depend on its effects on the membrane.

Photochemical Degradation of Picloram
Pesticide Science, 1982AbstractThe 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.

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, 1973AbstractGas 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, 1968Summary. 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, 1989Abstract 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 ...

A gas-chromatographic determination of residues of Picloram
The Analyst, 1967A method is described for the gas-chromatographic determination of Picloram herbicide in soils and plant material by using an electron-capture detector. The method described for soil has a sensitivity of 0·02 p.p.m. By the use of more rigorous clean-up procedures Picloram can be detected in other plant material at a level of 0·005 p.p.m., and ...
